ST62T40B/E40B

1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST62T40B and ST62E40B devices are low

cost members of the ST62xx 8-bit HCMOS family

of microcontrollers, which are targeted at low to

medium complexity applications. All ST62xx de-

vices are based on a building block approach: a

common core is surrounded by a number of on-

chip peripherals.

The ST62E40B is the erasable EPROM version of

the ST62T40B device, which may be used to em-

ulate the ST62T40B device, as well as the respec-

tive ST6240B ROM devices.
