Product details

16-bit HCS12X MCU for automotive and industrial control

The NXP S912XD128F2MAL-FR is a 16-bit microcontroller built around the HCS12X core, running at 80 MHz. It carries 128 KB of Flash program memory, 8K x 8 of RAM, and 2K x 8 of EEPROM — enough for moderate firmware loads in body control, sensor fusion, or motor drive applications. The -40°C to 125°C temperature grade and CANbus/LINbus connectivity make it a natural fit for automotive under-hood and industrial field-node designs.

Lifecycle and sourcing

It is ROHS3 compliant.

Frequently asked questions

What is the S912XD128F2MAL-FR's core speed?

The HCS12X core runs at 80 MHz. That is the headline throughput for this 16-bit MCU; bus timing and peripheral clock dividers are derived from it.

What are the equivalent or replacement parts for S912XD128F2MAL-FR?

A functional peer is the NXP MK51DX128CMC7, a 32-bit ARM Cortex-M4 MCU with 128 KB Flash and 72 MHz core. The architecture differs (ARM vs HCS12X), so code is not portable, but the memory density and peripheral set overlap for similar control applications.

How do I program the S912XD128F2MAL-FR microcontroller?

Programming is done via the standard HCS12 background debug module (BDM) interface. Most NXP toolchains and third-party programmers (PEmicro, Segger) support the HCS12X family. The 128 KB Flash is organized as 128K x 8 and can be programmed in-page or mass-erase mode.
