1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST62T53C, ST62T60C, ST62T63C and
ST62E60C devices are low cost members of the
ST62xx 8-bit HCMOS family of microcontrollers,
which is targeted at low to medium complexity ap-
plications. All ST62xx devices are based on a
building block approach: a common core is sur-
rounded by a number of on-chip peripherals.
The ST62E60C is the erasable EPROM version of
the ST62T60C device, which may be used to em-
ulate the ST62T53C, ST62T60C and ST62T63C
devices, as well as the respective ST6253C,
ST6260B and ST6263B 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 ST62T53C), a
serial port communication interface, an 8-bit A/D
Converter with 7 analog inputs and a Digital
Watchdog timer, making them well suited for a
wide range of automotive, appliance and industrial
applications.
