MC9S12151-4CG is an obsolete 8/16-bit microcontroller manufactured by Motorola/Freescale/NXP. It is based on the 68HC / HCS12 architecture and was typically used in embedded control, industrial automation, and legacy OEM designs. The device was offered in a TQFP package and qualified for commercial temperature operation. As an end-of-life component, production has ceased and procurement is generally limited to excess inventory, aftermarket suppliers, or authorized last-time-buy stock. Engineers typically evaluate form-fit-function replacements or redesigns when sourcing this device.
