ST6280B Datasheet - STMicroelectronics

GENERAL DESCRIPTION
INTRODUCTION
The ST62T80B and ST62E80B devices are low cost members of the ST62xx 8-bit HCMOS family of microcontrollers, which is 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 ST62E80B is the erasable EPROM version of the ST62T80B device, which may be used to emulate the ST62T80B device, as well as the respective ST6280B ROM devices.
