1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST62T00C,T01C,T03C and ST62E01C de-
vices are low cost members of the ST62xx 8-bit
HCMOS family of microcontrollers, which is target-
ed 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 ST62E01C is the erasable EPROM version of
the ST62T00C,T01C,T03C and
may be used to emulate the ST62T00C,T01C and
T03C
ST6200C,01C and 03C 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-

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 A/D Converter with up to
4 analog inputs and a Digital Watchdog timer,
making them well suited for a wide range of auto-
motive, appliance and industrial applications.
