Product details
Overview
S9S12G64AMLF from NXP Semiconductors (formerly Freescale) is a 16-bit automotive microcontroller featuring 64 KB flash, 4 KB SRAM, 2 KB EEPROM with ECC, one MSCAN module, two SCI/LIN interfaces, two SPI modules, and a 12-channel 10-bit ADC - deployed in body control modules and door modules requiring CAN/LIN communication and space-constrained PCB layouts.
For engineers reviewing the S9S12G64AMLF datasheet, S9S12G64AMLF pinout, S9S12G64AMLF application, or S9S12G64AMLF equivalent, key selection considerations include its 64-pin LQFP package, IPLL-based 25 MHz bus clock, integrated voltage regulator, and support for stop-mode wake-up via GPIO interrupts - critical for low-power automotive body electronics.
Technical Context
The S9S12G64AMLF implements the S12 CPU core with zero-wait-state 16-bit memory/peripheral access and an internal PLL (IPLL) that multiplies input clock to achieve a 25 MHz bus frequency while improving EMC performance. It integrates error correction code (ECC) on both flash and EEPROM for enhanced reliability in automotive environments.
Its peripheral set includes one MSCAN controller compliant with CAN 2.0A/B, two LIN-capable SCI modules supporting SAE J2602, and a 12-channel 10-bit successive-approximation ADC with precision fixed voltage reference - all mapped to dedicated registers accessible via standard S12 memory-mapped I/O space.
