STMicroelectronics ST10F280

INTRODUCTION

The ST10F280 is a new derivative of the ST Microelectronics 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.
