The ST92F120 Microcontroller
is developed and manufactured by STMicroelectronics using a pro- prietary n-well HCMOS process. Its performance derives from the use of a flexible 256-register pro- gramming 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 criti- cal application tasks to get the maximum use of core resources. The new-generation ST9 MCU devices now also support low power consumption and low voltage operation for power-efficient and low-cost embedded systems.
