Details are subject to change without notice. 1/4 1.1GENERAL DESCRIPTION The ST9293 is a ROM member of the ST9 family of microcontrollers, pletely developed and produced by SGS-THOMSON Microelectronics using a proprietary n-well HCMOS process. The ROM parts are fully patible with their EPROM versions, which may be used for the prototyping and pre-production phases of development, and can be configured as standalone microcontrollers with 48K/32K/24K/16 bytes of onchip ROM. The nucleus of the ST9293 is the advanced Core...
