Hi,
MK22_120MHz产品包括多款细分芯片，通常模块没有什么区别，一般只是Flash和SRAM大小之分。
KSDK软件提供MK22产品的模块驱动，可以通过下面链接中下载：
Software Development Kit for Kinetis MCUs|Freescale
目前基于MK22_120MHz的开发板有两款：
FRDM-K22F: FRDM-K22F|Freedom Development Board|Kinetis|Freescale
TWR-K22F120M: TWR-K22F120M|Tower System Module|Kinetis|Freescale
Have a great day,
Ma Hui
