STMicroelectronics ST9294
The ST9294 is a ROM member of the ST9 family of microcontrollers, completely developed and produced by SGS-THOMSON Microelectronics using a proprietary n-well HCMOS process. The ROM parts are fully compatible with their EPROM versions, which may be used for the prototyping and pre-production phases of development. The nucleus of the ST9294 is the advanced Core which includes the Central Processing Unit (CPU), the Register File, a 16-bit Timer/Watchdog with 8bit Prescaler, a Serial Peripheral Interface supporting S-bus, I2C-bus and IM-bus Interface, plus two 8-bit I/O ports.
