FS32K146HAT0MLHT Description

The 32-bit AEC-Q100 approved FS32K146HAT0MLHT MCU combines a series of scalable Arm? Cortex?-M based microcontrollers with a full complement of production-grade tools, supporting up to ASIL B functional safety automotive and industrial applications, and is built on long-lasting features.

The FS32K146HAT0MLHT MCU has low-power operating modes, a cryptographic security engine with NXP firmware, and an automotive-grade Software Development Kit (SDK) with the FreeRTOS? OS. There are three packaging options for the FS32K146HAT0MLHT MCU: QFN, LQFP, and MAPBGA.

FS32K146HAT0MLHT Features

• Power management

– Low-power Arm Cortex-M4F/M0+ core with excellent energy efficiency

– Power Management Controller (PMC) with multiple power modes: HSRUN, RUN, STOP, VLPR, and VLPS. Note: CSEc (Security) or EEPROM writes/erase will trigger error flags in HSRUN mode (112 MHz) because this use case is not allowed to execute simultaneously. The device will need to switch to RUN mode (80 MHz) to execute CSEc (Security) or EEPROM writes/erase.

– Clock gating and low power operation supported on specific peripherals.

• Memory and memory interfaces

– Up to 2 MB program flash memory with ECC

– 64 KB FlexNVM for data flash memory with ECC and EEPROM emulation. Note: CSEc (Security) or EEPROM writes/erase will trigger error flags in HSRUN mode (112 MHz) because this use case is not allowed to execute simultaneously. The device will need to switch to RUN mode (80 MHz) to execute CSEc (Security) or EEPROM writes/erase.

– Up to 256 KB SRAM with ECC

– Up to 4 KB of FlexRAM for use as SRAM or EEPROM emulation

– Up to 4 KB Code cache to minimize performance impact of memory access latencies

– QuadSPI with HyperBus? support

• Mixed-signal analog

– Up to two 12-bit Analog-to-Digital Converter (ADC) with up to 32 channel analog inputs per module

– One Analog Comparator (CMP) with internal 8-bit Digital to Analog Converter (DAC)

• Debug functionality

– Serial Wire JTAG Debug Port (SWJ-DP) combines

– Debug Watchpoint and Trace (DWT)
