1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST6365,67,75,77,85,87 microcontrollers are
members of the 8-bit HCMOS ST638x family, a
series of devices specially oriented to TV applica-
tions. Different ROM size and peripheral configu-
rations are available to give the maximum applica-
tion and cost flexibility. All ST638x 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 ST638x 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 (DH-
WD), a 14-bit voltage synthesis tuning peripheral,
a Serial Peripheral Interface (SPI), up to six 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 fol-
lowing memory resources are available: program
ROM (up to 20K), data RAM (256 bytes), EEP-
ROM (384 bytes). Refer to pin configurations fig-
ures and to ST638x device summary (Table 1) for
the definition of ST638x family members and a
summary of differences among the different types.
