6 / 72 page 6/72 ST62T40B/E40B INTRODUCTION (Cont’d) 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 programmability at low cost, which make them the ideal choice in a wide range of applications where frequent code changes, mul- tiple code versions or last minute programmability are required. These compact low-cost devices feature two Tim- ers comprising an 8-bit counter and a 7-bit pro- grammable prescaler, EEPROM data capability, a serial synchronous port interface (SPI), an 8-bit A/D Converter with 12 analog inputs, a Digital Watchdog timer, and a complete LCD controller driver, making them well suited for a wide range of automotive, appliance and industrial applications.
