INTRODUCTION
The ST62T42B and ST62E42B 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 ST62E42B is the erasable EPROM version of the ST62T42B device, which may be used to emulate the ST62T42B device, as well as the respective ST6242B ROM devices.

■ 3.0 to 6.0V Supply Operating Range
