8-BIT HCMOS MCUs FOR TV FREQUENCY & VOLTAGE SYNTHESIS WITH OSD

STMicroelectronics 

ST63140,142,126,156

GENERAL DESCRIPTION

The ST63140, 142, 126, 156 microcontrollers are

members of the 8-bit HCMOS ST631xx family, a

series of devices specially oriented to TV applica-

tions. Different ROM size and peripheral configura-

tions are available to give the maximum application

and cost flexibility. All ST631xx members are

based on a building block approach: a common

core is surrounded by a combination of on-chip pe-

ripherals (macrocells) available from a standard li-

brary. These peripherals 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 ST631xx family are: two Timer

peripherals each including an 8-bit counter with a

7-bit software programmable prescaler (Timer), a

digital hardware activated watchdog function

(DHWD), a 14-bit voltage synthesis tuning periph-

eral, a Serial Peripheral Interface (SPI), up to four

6-bit PWM D/A converters, an AFC A/D converter

with 0.5V resolution, an on-screen display (OSD)

with 15 characters per line and 128 characters (in

two banks each of 64 characters). In addition the

following memory resources are available: pro-

gram ROM (7K), data RAM (256 bytes), EEPROM

(128 bytes).

Refer to pin configuration figures and to ST631xx

device summary (Table 1) for the definition of

ST631xx family members and a summary of differ-

ences among the different types.
