ST92F250CV2QB Description
The ST92F124/F150/F250 microcontroller is developed and manufactured by STMicroelectronicsusing a proprietary n-well HCMOS process. Its performance derives from the use of a flexible256-register programming model for ultra-fast con-text 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-generationST9 MCU devices now also support low power consumption and low voltage operation for power-efficient and low-cost embedded systems.
