INTRODUCTION

The ST10R167 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS microcontrollers. It combines high CPU performance (up to 12.5 million instructions per second) with high peripheral functionality and enhanced I/O capabilities.

It also provides on-chip high-speed RAM and clock generation via PLL.
