GENERAL DESCRIPTION

INTRODUCTION

The ST9216x family brings the enhanced ST9 register-based architecture to a new range of high performance microcontrollers specifically designed for USB (Universal Serial Bus) applications. Their performance derives from the use of a

flexible 256-register programming model for ultrafast context switching and real-time event response. The intelligent on-chip peripherals offload the ST9 core from I/O and data management processing tasks allowing critical application tasks to get the maximum use of core resources.
