GENERAL DESCRIPTION
INTRODUCTION
The ST62T45B and ST62E45B 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 devices are based on a building block approach: a common core is surrounded by a number of on chip peripherals.
The ST62E45B is the erasable EPROM version of the ST62T45B device, which may be used to emulate the ST62T45B device, as well as the respective ST6245B ROM devices.
■ 3.0 to 6.0V Supply Operating Range
