INTRODUCTION

Description
The Lepton7 (Model R7100C), an embedded reader of the easy2read© product line, is an ultra compact reader for low power, high performance RAIN RFID applications.
With programmable output power from 10dBm to 30dBm, the reader can detect tags at more than 5 mt of distance (depending on antenna and tag dimensions).
Due to its low power consumption, the module is specifically designed to be easily integrated in battery powered devices. The radio frequency core of the module is based on the Impinj E710 IC that permits to achieve fast reading speed and to be used in dense reader and dense tag environments for top-class rated performances. The compactness of the device and the surface mount technology allow to embed the Lepton7 inside the new small form factor industrial handhelds, smartphone accessories and other compact form factor devices. The Lepton7 complies with and can operate in both European and US regulatory environments and, thanks to its multiregional capabilities, it’s ideal for integration in devices requiring compliance to different geographical regions. The Lepton7 is pin-to-pin compatible with the Impinj RS1000 and RS500 modules making it a perfect replacement for these devices.

HARDWARE INTERFACE

Introduction
An example Lepton7 R7100C system-level block diagram for an embedded system is shown in Fig. 3.1: Lepton7 R7100C – Example of Block Diagram. This figure shows the electrical connections that may and must be made to control the Lepton7 R7100C. In the figure, the required connections are illustrated with solid lines. Recommended and optional connections are illustrated with different dotted and dashed line patterns. More details for each connection are listed in the following paragraphs.

Required connections:

• VDC_IN and GND are required to power the Lepton7 R7100C.
• RF is required to connect to the UHF RFID antenna.
• UART1 Tx and Rx are required to communicate with the system host.

Recommended connections:

• nRST is used to reset the Lepton7 R7100C if UART communication is not available. This connection is highly recommended. This pin is internally driven strong low during software resets, so it should only be driven externally by an open drain signal. It must not be driven strong high.
• TST and BSL_SEL shall be used for the FW recovery/upgrade procedure.
  In order to start the Boot Strap Loader of Lepton7 internal microcontroller NRST, TST and BSL_SEL signals shall be driven as in the picture below:

BSL sequence
The BSL program execution starts when TST pin has received a minimum of two positive transitions and if TST is high while /RST rises from low to high. BSL_SEL shall be at high level before BSL starts. Pulses length and distance between edges of all signals shall be 10ms at least.

Optional connections:

• GPIOs allow interaction with the Lepton7 R7100C as both digital inputs and outputs. They may be used to trigger inventory, generate events based on inventory activity, or provide general-purpose user-controlled digital I/O.
• WKUP provides a mechanism to wake up the Lepton7 R7100C from the low power Sleep mode. If unused, this pin should be tied to logic low.
• UC_ADC allows use of an ADC to convert an analog input voltage into a digital value.
• UC_DAC allows use of a DAC to generate an analog output voltage from a digital value.
• RFU is a GPIO reserved for future use.

Power Supply

The Lepton7 R7100C is powered by a voltage applied to the VDC_IN pin (pin 11) relative to the GND pins. The supply voltage operating range is 4.75 V to 5.25 V. Current consumption varies from about 1400 mA to about 5mA depending on the operating mode. The power supply is internally bypassed and regulated, and no external bypass or bulk storage capacitance is required, as long as the input voltage is stable. If Lepton7 R7100C activity is not required at all times, and power reduction is desired, the VDC_IN supply voltage may be externally gated to remove power to the device.

RF Connection

The Lepton7 R7100C has a single RF pin (pin 1) which should be connected to a 50 Ω antenna via 50 Ω controlled impedance connection. This connection could simply be a microstrip transmission line to a PCB antenna or SMT antenna, or it could include a connector and coaxial cable. The RF connection is single ended, referenced to ground.
For more information about impedance matching, see PCB Layout for RF page 17.

UART Communication

The Lepton7 R7100C has two full-duplex UART standard interfaces, accessible using pins UART1-RX, UART1-TX, UART2-RX, and UART2-TX. UART1 implements the host communication interface via easy2read©, and UART2 implements the debug interface (RFU). The Tx pins are outputs from the Lepton7 R7100C, and the Rx pins are inputs to the Lepton7 R7100C. Both UART interfaces are 921,600 baud, with 8 data bits, 1 stop bit, and no parity bit (8-n-1 configuration). Each of the UART interfaces signals at 3.3 V relative to GND. The specific VIH, VIL, VOH and VOL specifications may be found in the § Device Input and Output Specifications paragraph page 15. The TX pins are driven strong high and low with a sink/source current of about 8 mA. If the load on a pin draws more than the 8 mA sink and source current, the pin is not guaranteed to meet the VOH and VOL specs listed in § Device Input and Output Specifications paragraph page 15. Excessive current sunk or sourced on the GPIO pins can also cause electrical damage to the device.
Warning: Voltages outside of the maximum IO operating voltage range of -0.3 to 4.0 V should not be applied to the UART pins. This can cause permanent damage to the device.

Reset Pin

The Lepton7 R7100C may be reset by a logic low voltage on the NRST pin (pin 9). Usage of this pin is recommended in all designs. It may be used to reset the part if an unexpected operating state is entered. The Lepton7 R7100C does have an internal watchdog circuit that will reset it if abnormal operation occurs, but the NRST pin provides a further level of reliability.
The NRST pin is pulled high (3.3 V) by an internal 51,1 kΩ nominal resistor. To reset the part, drive the pin strong low for at least the minimum reset pulse width as specified in § Device Input and Output Specifications paragraph page 15 (approximately 25 μs). This pin may be driven active low to reset the part, but should not be driven strong high. Driving the pin strong high prevents the Lepton7 R7100C from resetting itself in case user requested software reset. This pin should be driven using an “open drain drives low” drive mode, which creates either a strong low voltage or a floating voltage output.
Warning: Voltages outside of the maximum IO operating voltage range of -0.3 to 4.0 V should not be applied to the NRST pin. This can cause permanent damage to the device.

GPIO Pins

The Lepton7 R7100C’s GPIOs can be controlled using the easy2read© interface. Their drive mode, direction, and state are all controllable via easy2read©. There are two directions: input and output. In both input and output directions, there are three possible pin states: high, low, and float. For more details on using easy2read© to control the GPIOs, see the easy2read© protocol documentation. In the output direction, the GPIOs are driven strong high and low with a source and sink current of 8 mA, and in float mode the pin is not driven either high or low, leaving the pin floating, also known as “high impedance” or “high-Z”. The pins are driven to 3.3 V nominally. If the load on a pin draws more than the 8 mA sink and source current, the pin is not guaranteed to meet the VOH and VOL specs listed in the § Device Input and Output Specifications paragraph page 15.
Warning: Excessive current sunk or sourced on the GPIO pins can also cause electrical damage to the device.
In the input direction, the high and low states apply a pull-up or pull-down resistor, and in float mode the pin is not pulled either high or low, leaving the pin floating, also known as “high impedance” or “high-Z”. The pull-up and pull-down resistors are about 35 kΩ nominal. See the § Device Input and Output Specifications paragraph page 15 for more specific ratings. The inputs logic levels are proportional to 3.3 V. Specific VIH and VIL specs may be found in the § Device Input and Output Specifications paragraph page 15.
Warning: Voltages outside of the maximum IO operating voltage range of -0.3 to 4.0 V should not be applied to the pins, no matter their configuration. This can cause permanent damage to the device.

Wakeup Pin

The WKUP pin is used to wake the device when it is in the Standby or Sleep operating modes. This pin is edge sensitive and will wake the device on a rising edge. The WKUP pin must be logic low in order for the device to re- enter Idle mode after a Sleep wakeup, so it should only be pulsed high to wake up the part.
The WKUP pin operates at a 3.3 V logic level. It has a 35 kΩ typical pull-down resistor inside the Lepton7 R7100C. Voltages outside of the maximum IO operating voltage range of -0.3 to 4.0 V should not be applied to the WKUP pin. This can cause permanent damage to the device.
If the WKUP pin is not used, it should be left floating or tied to logic low (ground).

LAYOUT AND COMPONENTS

Introduction
This section describes hardware aspects of embedded RAIN RFID readers based on the Lepton7 R7100C.

PCB Layout for RF
50 Ohm Characteristic Impedance As discussed in paragraph RF Connection page 10, a properly matched RF connection is critical to achieving high performance with Lepton7 R7100C. An improperly matched RF connection will reduce performance in multiple ways, by both reducing the transmitted RF power, and also increasing the reflected power that interferes with Lepton7 R7100C’s receive circuitry. When impedance is improperly matched across a node, a signal’s reflection coefficient will be proportional to the difference between the characteristic impedances on both sides of the node divided by their sum, as shown in the following equation.

Reflection Coefficient of a Load:

In this equation, ZL represents the characteristic impedance of the transmission line, and Z0 represents the characteristic impedance of the Lepton7 R7100C, 50 Ohms. For example, if a 40 Ohm transmission line is used, the reflection coefficient will be = 10 / 90 = 11.1%, thus 11.1% of the power will be reflected back into the Lepton7 R7100C, and only 88.9% of the power will be transmitted. Lepton7 R7100C is designed to connect to a 50-Ohm characteristic impedance load. The connection between the Lepton7 R7100C module and its antennas should all be designed for a 50 Ohm characteristic impedance. Because the RF connection is made via PCB traces, this requires carefully designing the PCB layout.
PCB trace characteristic impedance depends on quite a few variables, only some of which can easily be controlled by the PCB designer. The two main categories of variables are the PCB geometry, and material properties. PCB geometry includes both the transmission line type, be it microstrip, stripline, or others, and also the specific dimensions of the forward and return paths and the adjacent dielectrics. Transmission line styles are shown in Fig. 4.1: PCB Transmission Line Types page 17. Material properties to note include the dielectric constant of the dielectrics in the PCB, and the conductivity of the conductor used.

In most PCB designs, many of the parameters of the PCB are already set, such as dielectric thickness and constant, trace conductivity and weight, etc. Usually, the only variables that can be easily modified are the style of transmission line, and its dimensions. The most common, and recommended PCB transmission line scheme is to use a microstrip on the top or bottom layer of the PCB, with a ground plane on the layer immediately adjacent as a return path. The width of this microstrip can then be varied to achieve the desired characteristic impedance. Care should be taken to ensure that the microstrip trace has enough current carrying capacity. This requires designing a trace that is heavy enough to withstand the heat generated by power losses due to the resistance of the trace.
There are many online resources and tools designed to assist in designing PCB transmission lines with the correct characteristic impedances. For example, the TXLine tool from National Instruments is very useful for performing these calculations automatically. There is also an online calculator on eeweb.com. These tools will require information about the PCB layout and also PCB characteristics, which should be obtained from the PCB manufacturer.

SMT Reflow Information

The solder manufacturer’s recommended reflow profile is shown in the following figure:

Moisture Sensitive Level 3 (MSL 3)
CAEN RFID srl follows JEDEC standards for moisture classifications. The Lepton7 R7100C RFID reader is classified as MSL 3.

Warning: The damaging effects of moisture absorbed in semiconductor packages during SMT assembly are known. Pay attention to the next paragraphs and follow the instructions to avoid  problems.

MSL 3 Handling at PCB Assembly
The Lepton7 R7100C package is moisture sensitive and needs to be handled within proper MSL 3 guidelines to avoid damage from moisture absorption and exposure to solder reflow temperatures that can result in yield and reliability degradation.

1. During PCB Assembly
2. Devices are baked and dry-packed before shipment from CAEN RFID. The packing uses a Moisture Barrier Bag (MBB). A Humidity Indicator Card (HIC) and drying desiccant are included inside the MBB. A MSL 3 label is attached to caution that the bag contains moisture sensitive devices.
3. Shelf life of devices in a sealed bag is 12 months at <40ºC and <90% room humidity (RH).
4. Upon opening of MBB, the HIC should be checked immediately; devices require baking before board mounting if the HIC is >10% when read at 23ºC ± 5ºC.
5. After MBB is opened, devices should go through reflow for board assembly within 168 hours at factory conditions of <30ºC/60% RH, or stored at <10% RH. If both conditions are not met, baking is required before board mounting.
6. If baking is required, devices should be baked for a minimum of 48 hours at 125ºC or 24 hours at 150°C.
7. Handling Unused Devices
8. Any unused devices after the MBB have been opened for more than 168 hours or not stored at <10% RH should be baked before any subsequent reflow and board assembly.
9. Re-baking should be done for a minimum of 48 hours at 125ºC or 24 hours at 150°C.
10. Unused devices can either be baked and dry-packed first before storage, or they can be baked just before the next board assembly. It is recommended that the former be practiced as it helps to prevent operator error from re-using devices without baking. In both cases, the re-packed materials should follow the guidelines in section A.C.
11. Reworking a Device on a PCB
12. Before a device is removed from the module, the module must first be baked.
13. Baking should be done for a minimum of 48 hours at 125ºC or 24 hours at 150°C.
14. It is recommended that during removal, localized heating be used, and the maximum body temperature of device should not exceed 200ºC.
15. The replacement device should not exceed the specified floor life of 168 hours.
