NXP Semiconductors PS32K144UAT0VLLA

Overview

PS32K144UAT0VLLA from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN operation, and integrated CSEc security engine. It supports CAN-FD, FlexCAN, LPUART/LIN, LPSPI, LPI2C, FlexIO, and dual 12-bit ADCs. Designed for body control modules, gateway ECUs, and battery management systems requiring ASIL-B compliance.

For engineers reviewing the PS32K144UAT0VLLA datasheet, PS32K144UAT0VLLA pinout, PS32K144UAT0VLLA application, or PS32K144UAT0VLLA equivalent, key selection considerations include its 144-pin LQFP package, -40 °C to +105 °C ambient rating (V-grade), 2.7–5.5 V supply range, HSRUN/RUN power mode switching requirement for CSEc/EEPROM operations, and pin-to-pin compatibility within the S32K14x family.

Technical Context

The PS32K144UAT0VLLA implements a dual-core architecture with Arm Cortex-M4F as primary core and optional M0+ for low-power co-processing. Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with configurable clock gating across peripherals including FlexCAN, LPUART, and LPIT.

Power management uses PMC with five modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc cryptographic operations and EEPROM emulation require explicit transition from HSRUN (112 MHz) to RUN (80 MHz) mode. Memory subsystem includes ECC-protected flash/SRAM, QuadSPI with HyperBus™ support, and FlexRAM configurable as SRAM or EEPROM.

Key Specifications

Pinout & Package

PS32K144UAT0VLLA is housed in a 144-pin LQFP package (16 × 16 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow the S32K14x family standard layout, supporting full peripheral mapping including three FlexCAN interfaces, two 12-bit ADC modules, and 156 GPIOs (with interrupt capability).

FAQ

What is the maximum operating frequency of the PS32K144UAT0VLLA and under what conditions?

The PS32K144UAT0VLLA operates at up to 112 MHz in HSRUN mode, which requires VDD ≥ 2.7 V and ambient temperature ≤ +105 °C. In RUN mode, it runs at 80 MHz and supports wider voltage (2.7–5.5 V) and temperature (-40 °C to +125 °C) ranges. The device must switch to RUN mode to execute CSEc security functions or EEPROM emulation - HSRUN mode disables these operations to prevent timing violations.

Does the PS32K144UAT0VLLA support CAN-FD, and how many interfaces are available?

Yes, the PS32K144UAT0VLLA supports CAN-FD on all three FlexCAN modules. Each module is compliant with ISO 11898-1 and supports bit rates up to 5 Mbps in FD mode. The 144-pin LQFP package routes all CAN_TX/CAN_RX signals to dedicated pins, enabling concurrent operation of multiple CAN-FD networks without resource contention.

What memory protection mechanisms are implemented in the PS32K144UAT0VLLA?

The PS32K144UAT0VLLA implements NXP's system-level Memory Protection Unit (MPU) at the Crossbar Switch, allowing independent access rights per master (CPU, DMA, Ethernet) to protected memory regions. It also includes ECC on 2 MB flash and 256 KB SRAM, CRC module for data integrity checks, and dual watchdogs (WDOG and EWM) - collectively meeting ASIL-B requirements per ISO 26262.

Can the PS32K144UAT0VLLA execute cryptographic operations while running at 112 MHz?

No. The PS32K144UAT0VLLA cannot execute CSEc cryptographic operations or EEPROM writes/erases while in HSRUN mode (112 MHz). Attempting such operations triggers error flags. The device must transition to RUN mode (80 MHz) first - this is a hardware-enforced restriction documented in the S32K1xx Data Sheet Rev. 15 to ensure timing closure and functional safety compliance.

What development tools and IDEs are officially supported for the PS32K144UAT0VLLA?

NXP officially supports PS32K144UAT0VLLA with S32 Design Studio (based on Eclipse and GCC), IAR Embedded Workbench, Green Hills MULTI, Arm Keil MDK, Lauterbach TRACE32, and iSystems winIDEA. SDKs include AUTOSAR-compliant drivers, MCAL libraries, and safety packages certified to ISO 26262 ASIL-B - all accessible via NXP's S32 Platform ecosystem.
