1 Introduction
1.1 Overview
This M519 Starter Kit (SRK) has been designed to help developers to create NFC/RFID HF systems based on the SpringCard SpringSeed M519 OEM NFC/RFID HF Module. The SRK allows to connect and use the M519 either through its USB or Serial interfaces directly from a desktop/laptop system or from an embedded computer board, as well as from a low-end microcontroller-based system thanks to the breakout pads. To work on contactless smart card or NFC/RFID HF applications, the SRK comes with three antennas of assorted size and a set of contactless cards, making it easy for customers to observe the practical communication range that could be achieved with either antenna. To work on contact smart card applications, the SRK features 3 different expansion boards, that hold either one ID-000 slot for a SIM/SAM card, or one ID-1 / plain size plus 4 ID-000 slots. This document is the user manual for the M519-SRK. It will guide you through the process of setting up and operating the M519 and its Starter Kit, exploring their features, and beginning the development of your application.

3.6 Serial interface
J20 is a BM08B-SRSS-TB(LF)(SN) JST 8-position connector. It is dedicated to connecting the M519 with its host, using the Serial port as primary interface.
The VCC (5V) power input may be used to power the SRK and the M519 at once (VIN_3V3 for the module is generated from VCC by a DC/DC located on the mother board).

PMD23175-AA

Warnings:
– The SERIAL TX and SERIAL RX lines operate at TTL/CMOS level. Do not attempt to connect J20 to a computer’s RS-232 port, or to a RS-485 interface directly.
– The SERIAL TX and SERIAL RX are buffered between the J20 connector and the M519 (and the J17 header). Thanks to the buffers, RX and TX lines on J20 are 3V, 5V-tolerant, where M519’s RX and TX lines are limited to 3V only.
– The host Serial interface may be implemented either with J20 “UART-TTL”, or with the FTDI USB to Serial bridge that is available on the USB-mini B connector J6 “USB-UART”. Do not connect anything on “UART-TTL” when “USB-UART” is connected.

3.7 Antenna interface
As a NFC/RFID HF coupler (PCD/VCD), the M519 needs a coil antenna to communicate with the contactless cards using inductive coupling over a 13.56MHz carrier. Chapter 7 introduces the principles of antenna sizing/designing, and the precautions to be taken during the integration to ensure correct operation of the system. On the M519-SRK, there are three different options to connect the external antenna: J12, J11 and J16. All the three antennas supplied in the kit connect through J12.
Warnings: – Never connect more than one antenna at the same time. – Always totally unpower (unplug) the M519-SRK before changing the antenna to prevent damaging the M519 RF frontend. Note: J12, J11 and J16 accept only antennas that have no integrated filter separating the RX signals from the TX signals. Therefore, they have only two active RF lines: – HF_ANT_P, that is connected to both HF_TXP and HF_RXP on the M519, – HF_ANT_N, that is connected to both HF_TXN and HF_RXN on the M519, To ensure the connection of the P / N signals, jumpers JP10 and JP11 must always be closed (default configuration).

3.8 Smart card interface
Once associated to the appropriate physical interface (ID-1 or ID-000 slot), the M519 is a contact smart card coupler.
Chapter 8 introduces how the M519 recognizes and uses the physical smart card interfaces. Such interfaces should be connected through J14. The three smart card daughter boards provided with the kit can be directly plugged onto this header.
JP14 controls whether the power supply of the smart card daughter boards is taken from the VOUT output (3.3V) of the M519 module, or taken from its V_RF_IN input (default configuration).

3.8.2 Power supply for the smart card daughter boards
The smart card daughter boards require two power signals: · The “digital” power supply, that feeds the ICs that are on the board. · The “card” power supply, that is used by the smart card interface IC to power the smart card(s). The smart card interface ICs have DC/DC converters to cover all the smart card power classes (A: 5V, B: 3.3V, C:1.8V) and to switch easily along them.
The “digital” power supply always comes from the 3.3V / 100mA output of the M519 (VOUT signal). This ensure that the I2C bus is at the right voltage, and is OK because the interface ICs need only a few mA to power their digital core. On the other hand, the “card” power supply must be ready to provide at least 50mA per card (that’s 250mA for one ID-1 plus four ID-000 slots)2. Therefore, this power supply must directly be taken from the external power source — namely V_RF_IN on the module. The voltage level could be either 5V (operation with an USB host) or 3.3V (operation with a Serial host), this makes no difference because the interface ICs have their DC/DC converters. JP14 controls the “card” power supply. For normal operation, it shall always remain on the bottom (“V_RF”) position.

2 Most smart cards will never require that amount of power (today’s cards have a typical consumption under 20mA), but the system must be designed to comply with the standards and be sized to cope with all situations.

4 Selecting the host interface
The M519 operates differently depending on which interface the host uses to communicate with it. The module knows which is its primary host interface by probing the power source upon reset:
· If a voltage is present on VBUS (USB 5V line), then the host interface is USB, · Otherwise, the M519 selects its Serial port as host interface. The power source for the RF interface must be set in coherence with the host interface: · If the host interface is USB, the RF interface shall be powered at 5V (i.e. VIN_RF
shall be connected to VBUS), · If the host interface is Serial, the RF interface shall be powered at 3.3V (i.e. VIN_RF
shall be connected to VIN_3V3). There are plenty of jumpers to move on the SRK board to set the host interface and the level of VIN_RF. Please follow the detailed instructions in the next paragraphs. Warning: Always totally unpower (unplug) the M519-SRK before changing the power configuration to prevent damaging the M519 or the SRK.

5 Selecting the operating mode
The M519 supports different operating modes: PC/SC Coupler (CCID protocol), Smart Reader, RFID Scanner (same Smart Reader but using HID keyboard protocol), etc. The module knows which is its operating mode by probing its MODE0 and MODE1 pin upon reset, and by reading the configuration stored in its non-volatile memory:
· If a specific configuration is assigned by MODE0, MODE1, the M519 activates the corresponding profile(s) and protocol(s),
· Otherwise, the M519 uses the profile(s) and protocol(s) selected in register H02C0.
5.1 Operating mode selected by HW

5.2 Operating mode selected in NVM
1. Write the expected operating mode in register H02C0: https://docs.springcard.com/books/SpringCore/Non_volatile_memory/Configuration/
Main_configuration/Profile See § 6.1 and 6.2 on how to write a new configuration in the M519. Alternatively, you may use the shell (“human console”) to alter a configuration.
2. Set both “MODE0” and “MODE1” switches to the OFF position, 3. Press the “RESET” button to activate the new configuration.
5.3 Bootloader
To M519 features a bootloader. The bootloader may be activated by driving the /FLASH pin of the M519 to low level, e.g. placing the SW2 switch of the SRK to the ON position. The bootloader is activated only when the M519 performs a cold reset (press S1 to do so or cycle power). For normal operation, the SW2 switch shall always be kept on the OFF position. Remark: most operating modes allow the host application to write a new firmware into the M519 through its “normal” communication protocol. This allows to flash the device without using the bootloader (hence without having to drive its /FLASH input).

6 Configuration and firmware upgrade
The M519 is a versatile device. In most use cases, it shall be configured carefully before being able to deliver the expected service to the host application.
The flexibility of the configuration covers:
· The main operating mode of the module (has seen in § 5.2 ), · The behaviour of the NFC/RFID HF interface: enabled protocols, allowed bitrates,
power level, compliance with the standards (ISO, EMV, CEN/TS 16794 or RCTIF, NFC Forum) and many options for fine-tuning the digital (protocol-level) and analog (RF) behaviours,
· The behaviour of the smart card interface(s): allowed bitrates, power class, compliance with the standards (ISO, EMV),
· The behaviour of the host interface: keyboard layout and typing speed for HID keyboard, protocol for Smart Reader operation, optimization of the CCID subsystem for different hosts/drivers,
· And more. All configuration registers are listed and detailed here:
https://docs.springcard.com/books/SpringCore/Non_volatile_memory/Configuration
The two preferred options for setting the configuration are SpringCard Companion and SpringCoreConfig.
This chapter also covers the firmware upgrade procedure, that could be performed with SpringCard Companion and SpringCoreFlash.

6.1.2 Using SpringCard Companion with an USB device
The Companion service is able to enumerate all the compliant USB devices. If the M519SRK is connected through USB, it appears immediately on the “Online” screen.
6.1.3 Using SpringCard Companion with a Serial device
Since Serial devices are not plug’n’play, the Companion service is not able to enumerate automatically. More than that, on USB the concept of compound devices makes it possible for the Companion service to communicate with the module using the Direct protocol even if another profile has been selected, but that is impossible with serial devices. Therefore, if the M519-SRK is connected through a serial port, you must
1. Enforce the Direct protocol, fail-safe mode. Refer to § 5.1.4 to do so,
