Description

The PCE84C886 is a member of the 84CXXX CMOS microcontroller family. PCE84C886 is suitable for use in 14", 15" and 17" auto-sync monitors for OSD and auto-sync applications. The device uses the PCE84CXX processor core and has 8 kbytes of ROM and 192 bytes of RAM. I/O requirements are adequately catered for with 12 general purpose bidirectional I/O lines plus 16 function combined I/O lines. 9 PWM analog outputs are provided specifically PCE84C886 for analog control purposes and also three 4-bit ADCs. The device has an 8-bit counter, suitable for use in pulse counting applications; an 8-bit timer/counter with programmable clock and an on-chip programmable PLL oscillator that generates the OSD clock. In addition to all these features a master-slave I2C-bus interface, 2 directly testable lines and an enhanced OSD facility for flexible screen format (64 character types) are also provided.

The block diagram of the PCE84C886 is shown in Fig.1.
