1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST6380, ST6381, ST6382, ST6383, ST6388,

ST6389 microcontrollers are members of the 8-bit

HCMOS ST638x family, a series of devices spe-

cially oriented to TV applications. Different ROM

size and peripheral configurations are available to

give the maximum application and cost flexibility.

All ST638x members are based on a building

block approach: a common core is surrounded by

a combination of on-chip peripherals (macrocells)

available from a standard library. These peripher-

als are designed with the same Core technology

providing full compatibility and short design time.

Many of these macrocells are specially dedicated

to TV applications. The macrocells of the ST638x

family are: two Timer peripherals each including

an 8-bit counter with a 7-bit software programma-

ble prescaler (Timer), a digital hardware activated

watchdog function (DHWD), a 14-bit voltage syn-

thesis tuning peripheral, a Serial Peripheral Inter-

face (SPI), up to six 6-bit PWM D/A converters, up

to 7 8-bit A/D Converter, an on-screen display

(OSD) with 20 characters per line and 192 charac-

ters (in one bank). In addition the following memo-

ry resources are available: program ROM (up to

20K), data RAM (256 bytes), EEPROM (384

bytes). Refer to pin configurations figures and to

ST638x device summary (Table 1) for the defini-

tion of ST638x family members and a summary of

differences among the different types.
