INTRODUCTION

The ST10F269 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS microcontrollers. It combines high CPU performance (up to 20 million instructions per second) with high peripheral functionality and enhanced I/O-capabilities. It also provides on-chip high-speed single voltage Flash memory, on-chip high-speed RAM, and clock generation via PLL.

ST10F269 is processed in 0.35µm CMOS technology. The MCU core and the logic is supplied with a 5V to 3.3V on chip voltage regulator. The part is supplied with a single 5V supply and I/Os work at 5V.
