Cache

• MCXA14x/15x features 4 KB Low-Power Cache Controller (LPCAC) RAM, which provides low-latency access to the instructions or data. The LPCAC RAM is placed on the core code bus. It can be configured as code tightly coupled memory (TCM) SRAM when LPCAC is disabled.

Flash

• MCXA14x/15x features up to 1 MB flash array, which is implemented as a single array. The flash array supports ECC on every 128 bits. It also supports the flash-swapping feature. The size of the smallest flash programming phrase is 16 bytes.
• The flash subsystem also includes a Memory Block Checker (MBC), Flash Memory Controller (FMC), and Flash Memory Module (FMU).
• FMC implements a 128-bit entry buffer and a 128-bit prefetch buffer. These buffers allow program code execution at a higher clock frequency than the frequency supported by flash memory. It accelerates flash memory transfers.

SRAM

• MCXA14x/15x features up to 128 KB SRAM, which is divided into several SRAM sections, including SRAM X0, X1, A0, A1, A2, A3, B0, B1, and B2.
• Therefore, different SRAM sections can be retained independently in a low-power mode to reduce power consumption.
• On every 32-bit aligned field, the 8 KB SRAM A0 section supports 2-bit error correction code (ECC) detection and 1-bit ECC correction. In addition, for functional safety diagnostic (self-test) purposes, MCXA14x/15x offers the Error Injection Module (EIM).
• The EIM module can be used to induce artificial errors in the RAM ECC. It can inject single-bit or multi-bit inversions into the data.
• To get 128 KB continuous SRAM addressing, the SRAM remap feature can be enabled, by remapping SRAM X0 right after SRAM B2.

Package options

• The MCXA14x/15x devices are available in different package options, including:
  • Traditional leaded packages (QFP) and non-leaded packages (QFN)
  • Advanced ball grid array (BGA) packages
• The variety of package options helps customers achieve reliable mechanical and thermal performance for their hardware designs.

Table 10 shows the package options available for the MCXA14x/15x devices.

Table 10. MCXA14x/15x package options

Package| Pin count| Number of GPIOs| Dimensions (length x width x thickness)| Pitch| Package drawing document number
---|---|---|---|---|---
VFBGA112 (PJ)| 112| 82| 7 x 7 x 0.86 mm| 0.5 mm| 98ASA02081D
LQFP100 (LL)| 100| 81| 14 x 14 x 1.4 mm| 0.5 mm| 98ASS23308W
LQFP64 (LH)| 64| 52| 10 x 10 x 1.4 mm| 0.5 mm| 98ASS23234W
LFBGA64 (MP)| 64| 50| 5 x 5 x 1.2 mm| 0.5 mm| 98ASA02085D
HVQFN48 (FT)| 48| 41| 7 x 7 x 0.9 mm| 0.5 mm| 98ASA01637D
HVQFN32 (FM)| 32| 26| 5 x 5 x 0.9 mm| 0.5 mm| 98ASA02110D

As shown in Table 10, the MCXA14x/15x devices are available in packages with pin counts as low as 32 (HVQFN32) to as high as 112 (VFBGA112). The low-pin- count packages allow the devices to be used for simple, low-cost PCB designs.

BGA packages

Ball grid array (BGA) is a popular packaging option for devices with high I/O requirements, especially for devices used in small form factor designs. The MCXA14x/15x device is available in the following two BGA packages:

• Very thin, fine pitch, ball grid array (VFBGA112)
• Low-profile, fine pitch, ball grid array (LFBGA64)

Figure 3 shows the MCXA156 device in a 5×5 mm, 0.5 mm pitch LFBGA64 package.

The ball pattern has been designed in such a manner that vias can be placed in the depopulated regions for easier fanout. The VDD and VSS signals are grouped conveniently, providing several options for fanning out the chip without requiring the via-in-pad technology. The MCXA14x/15x device in the LFBGA64 package can be used easily with low-cost 2-layer technology. Figure 4 shows an example layout for the MCXA14x/15x device in the LFBGA64 package.

LQFP packages

A low-profile, quad-flat package (LQFP) is a QFP package with reduced body thickness. The MCXA14x/15x device is available in the following two LQFP packages:

• LQFP100
• LQFP64

An MCXA14x/15x LQFP package does not have an exposed pad underneath the package that could act as an aground connection and/or heat sink.

HVQFN packages

A heat sink, very thin, quad flat package, non-leaded (HVQFN) is equipped with electrode contacts (instead of leads) around all four sides of the chip. It allows an HVQFN package to have a smaller mounting area and lower height, as compared to a QFP package. An exposed thermal pad on the bottom side of a QFN package can be soldered directly to the system PCB to increase heat emission from the die.

The MCXA14x/15x device is available in the following two HVQFN packages:

• HVQFN48
• HVQFN32

The MCXA14x/15x HVQFN48 package has some inner exposed leads, as shown in Figure 5. While designing the hardware, do not solder these exposed leads to the PCB. Cover this area with a solder mask for easier signal routing.

To find a package drawing, go to nxp.com. and perform a search operation using the package drawing document number as the search keyword. To find the document number of a package drawing, see Table 10.

Pin compatibility

The MCXA14x/15x family devices are mostly pin-to-pin compatible except for a few pins, such as ISP (ISPMODE_N). The ISP pin determines whether to boot from the internal flash memory or to run into ISP mode, after reset.

Table 11 compares the ISP pin assignment across the MCXA14x/15x family devices.

Table 11. MCXA14x/15x family ISP pin assignment comparison

Minimum system

While designing the hardware, one of the initial steps is to determine the minimum system components required to run the MCU. For the MCXA14x/15x family devices, the key system components include reset, ISP, debug, power, and optionally, clock. The state of the ISP pin at reset determines the boot source of the MCXA14x/15x MCU. If the ISP pin is pulled down, the MCU enters ISP boot mode; otherwise, it boots from the internal flash memory. Figure 6 shows the minimum system for an MCXA14x/15x device.

Power supplies

MCXA14x/15x operates in the power supply range from 1.71 V to 3.6 V. It has multiple power domains that can be put into different power modes independent of each other, for power efficiency. Multiple power supplies are available to supply power to the power domains and I/O ports. Figure 7 shows the MCXA14x/15x power supply scheme.

The input power supplies shown in Figure 7 are explained below:

• Digital power supply (VDD): The VDD supply is used for the following purposes:
  • It supplies power to the system power domain and I/O ports except port 3. The system power domain mainly includes System Power Control (SPC), High-Voltage Detect (HVD) / Low-Voltage Detect (LVD), Wake-Up Unit (WUU), and Low-Power Timer (LPTMR).
  • It supplies power to the core power domain through an internal LDO. The core power domain supports the dynamic voltage and frequency scaling (DVFS) feature. This feature allows you to scale up/down the voltage depending on the desired MCU core frequency. For example, if you want to run the core clock at the maximum frequency (96 MHz), the core voltage must be kept at 1.1 V. However, if your application can tolerate running at a lower frequency (even for a short period), decrease the core voltage. Decreasing the core voltage reduces the power consumption.
• Analog power supply (VDD_ANA): The VDD_ANA supply is used to power up the analog power domain, including the ADC module. Usually in hardware designs, VDD_ANA is connected to VDD. If you want to improve ADC accuracy, you can use an independent power supply to power up VDD_ANA. However, ensure that the voltage difference between VDD_ANA and VDD is within ±0.1 V, as specified in the MCXA14x/15x data sheets.
• USB power supply (VDD_USB): The VDD_USB supply is used to power up the USB domain. For VDD_USB, the voltage must be kept within the range from 3 V to 3.6 V. If the USB domain is not used, VDD_USB can be tied to the ground through a 10 kΩ resistor.
• Optional (independent) port 3 power supply (VDD_P3): On some MCXA14x/15x parts, an independent power supply VDD_P3 is used to power up I/O port 3 for 1.2 V I/Os. VDD_P3 operates in the voltage range from 1.14 V to 3.6 V.

Bulk and decoupling capacitors

Bulk and decoupling capacitors help the MCU chip operate properly:

• A bulk capacitor is used to provide a local power supply to an MCU pin.
• A decoupling capacitor, if shorted to the ground, helps in preventing noise from entering the MCU chip.

Figure 8 shows an example circuit diagram with bulk and decoupling capacitors.

Follow these recommendations when using bulk and decoupling capacitors in your hardware design:

• Use decoupling capacitors that exhibit low reactance in the desired frequency ranges.
• For each power pin, use a decoupling capacitor with a capacitance value of 0.1 μF.
• For each power domain, use a bulk capacitor with a capacitance value in the range from 2.2 μF to 10 μF.
• Place the decoupling and bulk capacitors as near as possible to their respective MCU pins.

Power supply considerations
While designing the hardware, follow these power supply considerations:

• The VDD_ANA supply must be at the same voltage level as the VDD supply, and both supplies must be ramped up together.
• The VDD_P3 supply (I/O supply of port 3) must be ramp up together with or after VDD. If you want to shut down VDD_P3, assert the isolation in the SPC EVD_CFG register before shutting down VDD_P3 in active mode.

Clock

The MCXA14x/15x MCU includes an external oscillator module — a system oscillator (SOSC) with an external 8–50 MHz crystal. Figure 9 shows an example system oscillator circuit diagram.

Debug and programming interface

Reset system

• Resetting the MCU provides a way to start processing from a known set of initial conditions. When a system reset begins:
  • The on-chip regulator gets full control over the power supplies
  • The system clock gets generated from an internal reference clock

External reset pin (RESET_B)

The RESET_B pin is a bidirectional open-drain pin with an internal pull-up resistor. Asserting RESET_B wakes the MCU from any mode. In MCXA14x/15x, the RESET_B function is multiplexed on the GPIO pin P1_29, and this function is the default function of the pin.

The RESET_B pin works in the following two manners:

• During active and low-power modes, the RESET_B pin can be asserted externally to force the chip into pin reset condition.
• During reset, the RESET_B pin drives low until the chip has completed hardware initialization. At this point, the RESET_B pin is released. If the pin is asserted externally, the MCU remains in reset until the RESET_B input is pulled high.
• The RESET_B pin implements a digital filter for filtering out glitches from the pin. You can configure the filter through software to filter out glitches that are less than 1–32 cycles of the Core Mode Controller (CMC) clock. The filter is bypassed in low-power modes if the CMC clock is disabled.

JTAG/SWD interface

The MCXA14x/15x MCU supports a JTAG / serial wire debug (SWD) debug interface using a low-cost, 10-pin, 0.05″ connector. Because the connector supports both JTAG and SWD signals; therefore, you can configure an external debugger in either JTAG or SWD mode to debug an MCXA14x/15x MCU. The JTAG/SWD connector offers Instruction Trace Macrocell (ITM) and Data Watchpoint and Trace (DWT) trace information.
In SWD mode, the following two pins are used for debugging:

• Bidirectional SWDIO pin, which is used for data transfer
• SWDCLK pin, which is used for clocking the data
• A third pin SWO delivers the trace data at a low system cost. The JTAG and SWD pins are shared.

Table 12 shows the MCXA14x/15x debug pin assignments.

Table 12. MCXA14x/15x debug pin assignments

Pull-up
RESET| RESET| Reset MCU| P1_29| Pull-up
GND| GND| Ground| VSS| –

As shown in Table 12, the MCXA14x/15x debug pins have internal pull-up/down resistors, by default. To make the debugger connection more robust, you can add external pull-up/down resistors for the JTAG/SWD signals. NXP also recommends adding electrostatic discharge (ESD) diodes for critical pin connections.

Figure 10 shows an example debug interface circuit diagram.

MCXA14x/15x also allows using JTAG and boundary scans for performing probe- less device connectivity tests. For details, refer to How To Perform Boundary Scan On MCXA Series Using μTrace And Trace32 (AN14209).

ISP programming

Besides an external JTAG/SWD debugger, you can also use in-system programming (ISP) to program the MCXA14x/15x MCU. During MCU reset, the state of the MCU ISP pin (ISPMODE_N) determines whether to enter normal boot flow or enter ISP mode. In ISP mode, you can program the MCU through the ISP boot peripherals. Depending on the device part, the default ISP pin is P0_6 or P3_29. For more details on ISP pin assignment, see Table 11.

Table 13 shows the default ISP boot peripherals and corresponding pin assignments.

Table 13. MCXA14x/15x ISP boot peripherals

Figure 11 shows an example circuit diagram for the MCXA156 MCU with an ISP push button SW3 for entering ISP mode. Pressing the ISP button asserts the MCXA156 MCU pin P0_6 (ISPMODE_N), which forces the MCU extended bootloader to run in ISP mode.

Unused pins

Table 14 provides recommendations for terminating the unused pins of the MCXA14x/15x MCU.

Table 14. Recommendations for terminating unused pins

Pins| Default state| Recommended way for terminating unused pins
---|---|---
Digital/analog pins| Disabled| Leave unconnected. Configuring the multiplexing mode of a pin as disabled or analog (PCRn[MUX] = 0) disables the input buffer of the pin. It results in reduced power consumption.
P1_29/RESET_B| Input with default internal pull-up resistor| If the RESET_B pin is not used, it can be left unconnected and:

•   Configured as GPIO by setting PCR9[MUX] = 0

•   Disabled by setting PCR9[IBE] = 0

P3_29/ISPMODE_N, P0_6/ISPMODE_N| Input with default internal pull-up resistor| Leave unconnected. Configuring the multiplexing mode of a pin as disabled or analog (PCRn[MUX] = 0) disables the input buffer of the pin. It results in reduced power consumption.
P130/XTAL48M, P1 31/EXTAL48M| Disabled| Leave unconnected
VDD_USB|  | Tie the unused VDD_USB pin to the ground through a 10 kΩ resistor.
USB_DP|  | Leave unconnected
