MCU for automotive body and industrial control — 112 MHz Cortex-M4F with 512 KB Flash
The NXP FS32K144UIT0VLHT is a 32-bit ARM Cortex-M4F MCU from the S32K series, clocked at 112 MHz with a single core. It carries 512 KB of Flash program memory, 64 KB of SRAM, and 4 KB of on-chip EEPROM — enough for a full automotive body controller or a multi-axis industrial motor drive firmware stack without external storage. The part is rated for -40°C to 105°C ambient. Supply range spans 2.7 V to 5.5 V. On-chip peripherals include a 16-channel 12-bit SAR ADC and one 8-bit DAC for analog sensor and actuator interfaces, plus CANbus, LINbus, I²C, SPI, and UART/USART connectivity for both automotive and industrial fieldbuses. The 58 general-purpose I/O pins in a 64-LQFP (10x10 mm) package give enough headroom for a typical body controller or I/O module.
112 MHz core — what it buys you on a CAN bus or motor drive
At 112 MHz, the Cortex-M4F can execute a PID loop, read the ADC, and update a PWM duty cycle within a few microseconds. The 64 KB SRAM supports moderate data buffering.
512 KB Flash + 4 KB EEPROM — firmware and calibration storage
The 512 KB Flash holds a full AUTOSAR stack or a custom application with room for bootloader, application image, and a small over-the-air update buffer. The 4 KB EEPROM is mapped into the memory space and can store calibration tables, fault codes, and production parameters without an external serial EEPROM. Write endurance is typical of on-chip EEPROM — adequate for infrequent parameter updates, not for high-frequency data logging.
Lifecycle and compliance — current production, ROHS3
No last-time-buy or end-of-life notice applies. The part is ROHS3 compliant, meeting the latest EU RoHS exemption-free requirements.
