ST92F250CV2QB [STMicroelectronics]

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.
