GENERAL DESCRIPTION
INTRODUCTION
The ST6380, ST6381, ST6382, ST6383, ST6388, ST6389 microcontrollers are members of the 8-bit HCMOS ST638x family, a series of devices specially oriented to TV applications. Different ROM size and peripheral configurations are available to give the maximum application and cost flexibility.
