8位OTP / EPROM微控制器与A / D转换器，国家外汇管理局复位，自动重装定时器和EEPROM 8-BIT OTP/EPROM MCUs WITH A/D CONVERTER, SAFE RESET, AUTO-RELOAD TIMER AND EEPROM
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.
The ST62E62C is the erasable EPROM version of the ST62T62C device, which may be used to emulate the ST62T52C and ST62T62C devices as well as the ST6252C and ST6262B ROM devices.
