4 / 70 page 4/70 ST62T15C/T25C/E25C 1 GENERAL DESCRIPTION 1.1 INTRODUCTION The ST62T15C,T25C and ST62E25C 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 de- vices are based on a building block approach: a common core is surrounded by a number of on- chip peripherals. The ST62E25C is the erasable EPROM version of the ST62T15C,T25C device, which may be used to emulate the ST62T15C,T25C device, as well as the respective ST6215C,25C 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 bytes 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 A/D Converter with 16 analog inputs and a Digital Watchdog timer, mak- ing them well suited for a wide range of automo- tive, appliance and industrial applications.
