MC9S08GT16ACFBE

MC9S08GT16ACFBE is an 8‑bit microcontroller from NXP Freescale, in the HCS08/GT family. It combines on‑chip flash memory (16 KB) with a small RAM area and a rich peripheral set, including ADC, timers, a watchdog, and communication interfaces (SCI/UART, SPI, I2C), plus PWM outputs and a real‑time counter. It runs from about 1.8–5.5 V and can operate up to roughly 25 MHz, with low‑power modes and built‑in debugging/boot features. The ACFBE suffix encodes package type, temperature/voltage grade, and related specs. Typical applications: automotive control modules, motor control, and general embedded control tasks.

MC9S08GT16ACFBE is an HCS08 GT16 MCU with 16 KB flash. There isn’t a direct one-to-one cross‑vendor equivalent. Within NXP, closest options are other GT16 variants in different packages/temperature grades (e.g., MC9S08GT16 with alternate suffixes). For a true drop‑in, use NXP’s cross‑reference tool. If a substitute from another vendor is acceptable, you’d pick a different 8‑bit HCS08/ST8 part, but it won’t be pin‑for‑pin compatible.
