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.
