GENERAL DESCRIPTION

The ST63E140/T140, E142/T142, E126/T126,

E156/T156 microcontrollers are members of the 8-

bit HCMOS ST631xx family, a series of devices

specially oriented to TV applications. Different pe-

ripheral configurations 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 com-

bination of on-chip peripherals (macrocells) avail-

able from a standard library. 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 ap-

plications.

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

peripheral, a Serial Peripheral Interface (SPI), up

to four 6-bit PWM D/A converters, an AFC A/D con-

verter with 0.5V resolution, an on-screen display

(OSD) with 15 characters per line and 128 charac-

ters (in two banks each of 64 characters). In addi-

tion the following Memory resources are available:

program EPROM (8K), 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.
