5 / 84 page 5/84 ST62T28C/E28C 1 GENERAL DESCRIPTION 1.1 INTRODUCTION The ST62T28C and ST62E28C devices are low cost members of the ST62xx 8-bit HCMOS family of microcontrollers, which are 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 ST62E28C is the erasable EPROM version of the ST62T28C device, which may be used to em- ulate the ST62T28C device, as well as the respec- tive ST6228C 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 advan- tages of user programmability at low cost, which make them the ideal choice in a wide range of ap- plications 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, with 1 input capture channel, capability, a serial asyn- chronous port interface (UART), a synchronous serial port interface, an 8-bit A/D Converter with 12 analog inputs and a Digital Watchdog timer, mak- ing them well suited for a wide range of automo- Figure 1.
