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,
multiple code versions or last minute programma-
bility 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 8 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.
