ST62T35B/E35B

1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST62T35B and ST62E35B devices are low

cost members of the ST62xx 8-bit HCMOS family

of microcontrollers, which is targeted at low to me-

dium complexity applications. All ST62xx devices

are based on a building block approach: a com-

mon core is surrounded by a number of on-chip

peripherals.

The ST62E35B is the erasable EPROM version of

the ST62T35B device, which may be used to em-

ulate the ST62T35B device, as well as the respec-

tive ST6235B ROM devices.
