Freescale Semiconductor TWR-S12G64 Scalable Platform for Automotive Applications TWR-S12G64-KIT TWR-S12G64-KIT 信息指南

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.
