INTRODUCTION
The ST6208C, 09C, 10C and 20C devices are low cost members of the ST62xx 8-bit HCMOS family of microcontrollers, which is targeted at low to medium complexity applications. All ST62xx devices are based on a building block approach: a common core is surrounded by a number of on-chip peripherals.
The ST62E20C is the erasable EPROM version of the ST62T08C, T09C, T10C and T20C devices, which may be used during the development phase for the ST62T08C, T09C, T10C and T20C target devices, as well as the respective ST6208C, 09C, 10C and 20C ROM devices.
