5 / 86 page 5/86 ST62T55C ST62T65C/E65C 1 GENERAL DESCRIPTION 1.1 INTRODUCTION The ST62T55C, ST62T65C and ST62E65C devic- es are low cost members of the ST62xx 8-bit HC- MOS family of microcontrollers, which is targeted at low to medium complexity applications. All ST62xx devices are based on a building block ap- proach: a common core is surrounded by a number of on-chip peripherals. The ST62E65C is the erasable EPROM version of the ST62T65C device, which may be used to em- ulate the ST62T55C and ST62T65C device, as well as the respective ST6255C and ST6265C ROM devices. OTP and EPROM devices are functionally identi- cal. The ROM based versions offer the same func- tionality selecting as ROM options the options de- fined in the programmable option byte of the OTP/ EPROM versions. OTP devices offer all the advantages of user pro- grammability at low cost, which make them the ideal choice in a wide range of applications where frequent code changes, multiple code versions or last minute programmability are required. These compact low-cost devices feature a Timer comprising an 8-bit counter and a 7-bit program- mable prescaler, an 8-bit Auto-Reload Timer, EEPROM data capability (except ST62T55C), a serial port communication interface, an 8-bit A/D Converter with 13 analog inputs and a Digital Watchdog timer, making them well suited for a wide range of automotive, appliance and industrial applications.
