7 / 86 page  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. ® ST63140,142,126,156 3/82 |
