For engineers reviewing the MCXA155VPJ datasheet, MCXA155VPJ pinout, MCXA155VPJ application, or MCXA155VPJ equivalent, key selection criteria include its 96 MHz Cortex-M33 core with FPU and DSP extensions, -40 °C to 125 °C operating range, Deep Power Down current of 412 nA, 5V-tolerant I/O capability on P3_27/P3_28, and support for CAN FD and I3C interfaces.

Technical Context

The MCXA155VPJ implements a single-core Arm Cortex-M33 CPU without TrustZone or MPU, operating at 96 MHz with 1.1 V core supply and full FPU/DSP instruction support. It integrates a 4 KB cache engine, 16 KB ROM bootloader, and hardware security monitoring including Code Watchdog and GLIKEY register protection.

Its power architecture includes an integrated LDO_CORE regulator, configurable IO supply (1.2 V on P3 port), and five low-power modes - Deep Sleep (32.26 μA), Power Down (8.2 μA), and Deep Power Down (412 nA) - with wake-up sources active down to the deepest state.

FAQ

What is the maximum operating frequency and core voltage for MCXA155VPJ?

The MCXA155VPJ operates at a maximum core frequency of 96 MHz with a core supply voltage of 1.1 V. This is delivered by the integrated LDO_CORE regulator, which supports normal and low-drive strength modes. The device maintains full peripheral functionality and timing accuracy across its -40 °C to 125 °C operating range at this speed. All performance specifications, including CoreMark score (396 @ 96 MHz), are validated at this configuration.

Does MCXA155VPJ support CAN FD, and what are its physical layer requirements?

Yes, MCXA155VPJ includes one FlexCAN module supporting CAN FD protocol with bit rates up to 5 Mbps and payloads up to 64 bytes. It requires an external CAN transceiver connected to CAN0_TX and CAN0_RX pins. The MCU provides programmable timing registers, loopback mode for self-test, and error counters compliant with ISO 11898-1:2015. No external oscillator is needed - the internal FRO192M serves as the clock source.

How many ADC channels does MCXA155VPJ support, and what is their resolution and speed?

The MCXA155VPJ integrates two independent 16-bit SAR ADCs. Each supports up to 32 input channels (multiplexed across GPIOs), 3.2 Msps sampling rate in 16-bit mode, and 4 Msps in 12-bit mode. Each ADC includes an integrated temperature sensor. Conversion results are accessible via DMA or CPU polling, and both ADCs can operate concurrently in low-power modes including Deep Sleep.

What package type and pin count does MCXA155VPJ use, and are there thermal or moisture sensitivity considerations?

MCXA155VPJ uses a VFBGA-112 package (7 mm × 7 mm, 0.5 mm pitch, 0.86 mm height) with JEDEC-standard MSL 3 moisture sensitivity rating. Its thermal handling supports lead-free reflow up to 260 °C peak, and storage temperature ranges from -55 °C to +150 °C. The package exposes 82 GPIOs and supports 50 MHz I/O speeds on P1/P3/P4 ports - critical for high-speed sensor or display interfaces.

Is MCXA155VPJ compatible with NXP's MCUXpresso SDK and development tools?

Yes, MCXA155VPJ is fully supported by the NXP MCUXpresso SDK, IDE, and configuration tools. The SDK includes device-specific drivers for all peripherals (FlexCAN FD, USB FS, FlexPWM, ADC), middleware for FreeRTOS and lwIP, and example projects for motor control, USB audio, and low-power sensing. MCUXpresso Config Tools generate initialization code directly from graphical peripheral setup - accelerating development for MCXA155VPJ-based designs.
