ST62T80B/E80B
1 GENERAL DESCRIPTION
1.1 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 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 ST62E80B is the erasable EPROM version of
the ST62T80B device, which may be used to em-
ulate the ST62T80B device, as well as the respec-
tive ST6280B ROM devices.
