Note:
Stresses above those listed as "absolute maximum ratings" may cause permanent damage to the device. This is  a stress rating only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. All voltages are referenced to VSS=0.

The ST92F120 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 onchip peripherals offload the ST92F120 core from I/O and data management processing tasks allowing critical application tasks to get the maximum use of core resources. The new-generation ST92F120 MCU devices now also support low power consumption and low voltage operation for power-efficient and low-cost embedded systems.
