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

device, which

may be used to emulate the ST62T00C,T01C and

T03C

device,

well

the

respective

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-

fined in the programmable option bytes 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 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.
