Overview
MC9S12GC128MFUE from NXP (formerly Freescale) is a 16-bit HCS12 microcontroller featuring 128 KB on-chip Flash, 8 KB RAM, and integrated CAN 2.0A/B controller, PWM, ATD10B8C 10-bit ADC (8-channel), and BDM debug interface. It operates at up to 25 MHz core frequency with internal PLL, supports automotive-grade temperature range (–40°C to +125°C), and targets engine control units, body electronics, and industrial motor control.
For engineers reviewing the MC9S12GC128MFUE datasheet, MC9S12GC128MFUE pinout, MC9S12GC128MFUE application, or MC9S12GC128MFUE equivalent, key selection criteria include its 80-pin LQFP package, S12 CPU core compatibility, CAN bus integration, Flash endurance (10k erase/write cycles), and qualification per AEC-Q100 Grade 1.
Technical Context
The MC9S12GC128MFUE implements the S12 CPU core with 16-bit data path and 24-bit address space, executing instructions in single-cycle (most) or two-cycle (indexed) modes.
