8-BIT OTP/EPROM MCU WITH LCD DRIVER, EEPROM AND A/D CONVERTER

STMicroelectronics 

ST62T46B/E46B

1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST62T46B and ST62E46B 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 ST62E46B is the erasable EPROM version of

the ST62T46B device, which may be used to em-

ulate the ST62T46B device, as well as the respec-

tive ST6246B ROM devices.
