GENERAL DESCRIPTION
INTRODUCTION
The ST62T52C and ST62T62C devices is 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.
