A Comprehensive Guide To S9S12G128AMLHR Microcontroller IC 16-Bit 25MHz 128KB (128K x 8) FLASH 64-LQFP (10x10)

12V1 HCS12 Microcontroller IC 16-Bit 25MHz 128KB (128K x 8) FLASH 64-LQFP (10x10)

Overview

The Freescale Semiconductor MC9S12G family is a feature-rich 16-bit microcontroller product line

focused on low cost, high performance and low pin count for automotive applications. This

family bridges the gap between high-end 8-bit microcontrollers and high-performance 16-bit

microcontrollers, such as the MC9S12XS family. The MC9S12G family is targeted at generic

automotive applications requiring CAN or LIN/SAE J2602 communication and is used in applications

such as body controllers, door modules, occupant detection and lighting modules.

The MC9S12G family uses many of the same features found on the MC9S12XS and MC9S12P

family, including error correction code (ECC) on flash memory, a fast analog-to-digital converter

(ADC) and a frequency modulated phase locked loop (IPLL) that improves the EMC performance. In

order to make using the MC9S12G family easier in your embedded designs, it features an EEPROM

with a small erase sector size.
