GENERAL DESCRIPTION
The PCE84C486 and PCE84C487 are low-cost
microcontrollers and have been designed for use with
auto-sync monitors, handling mode detection, digital
control and Voltage Synthesized Tuning (VST). These
microcontrollers have no on-chip OSD function.
The term PCE84C48X is used throughout this data sheet
to refer to both devices. Differences between the
PCE84C486 and the PCE84C487 are highlighted
throughout the document.
The PCE84C48X is a member of the 84CXXX CMOS
microcontroller family. The device uses the PCE84CXX
processor core and has 4 kbytes of ROM and 128 bytes of
RAM. I/O requirements are catered for with 11 general
purpose bidirectional I/O lines (the PCE84C487 has 12)
plus 12 function combined I/O lines (the PCE84C487 has
16). Nine PWM analog outputs (the PCE84C487 has 13)
are available for analog control purposes and also a two
channel 4-bit ADC. The device has an 8-bit counter (T3),
for use in pulse counting applications and also an 8-bit
timer/counter (T1) with programmable clock. A Watchdog
timer, a master-slave I
2
C-bus interface and 2 directly
testable lines are also available on-chip.
The block diagram of the PCE84C486 is shown in Fig.1;
the block diagram of the PCE84C487 is shown in Fig.2.
