FS32K144UAT0VLLT Description

A scalable family of 32-bit Arm? Cortex?-M4F and Cortex-M0+ based MCUs with AEC-Q100 qualification, the FS32K144UAT0VLLT is designed for general-purpose automotive and high-reliability industrial applications. With different performance, memory, and feature options, FS32K144UAT0VLLT provides scalability with hardware and software compatible families. These FS32K144UAT0VLLT MCUs provide ISO, CAN FD, CSEc hardware security, ASIL-B ISO26262 functional safety, and ultra-low power performance.

FS32K144UAT0VLLT Features

? Operating characteristics

– Voltage range: 2.7 V to 5.5 V

– Ambient temperature range: -40 °C to 105 °C for

HSRUN mode, -40 °C to 150 °C for RUN mode

? Arm? Cortex-M4F/M0+ core, 32-bit CPU

– Supports up to 112 MHz frequency (HSRUN mode)

with 1.25 Dhrystone MIPS per MHz

– Arm Core is based on the Armv7 Architecture and

Thumb?-2 ISA

– Integrated Digital Signal Processor (DSP)

– Configurable Nested Vectored Interrupt Controller

(NVIC)

– Single Precision Floating Point Unit (FPU)

? Clock interfaces

– 4 - 40 MHz fast external oscillator (SOSC) with up

to 50 MHz DC external square input clock in

external clock mode

– 48 MHz Fast Internal RC oscillator (FIRC)

– 8 MHz Slow Internal RC oscillator (SIRC)

– 128 kHz Low Power Oscillator (LPO)

– Up to 112 MHz (HSRUN) System Phased Lock

Loop (SPLL)

– Up to 20 MHz TCLK and 25 MHz SWD_CLK

– 32 kHz Real Time Counter external clock

(RTC_CLKIN)

? 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.
