INTRODUCTION

The ST92F124/F150/F250 microcontroller is developed and manufactured by STMicroelectronics

using a proprietary n-well HCMOS process. Its performance derives from the use of a flexible 256-register programming model for ultra-fast 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. The new-generation ST9MCU devices now also support low power consumption and low voltage operation for power efficient and low-cost embedded systems.
