This is a monitor microcontroller product with DDC interface, auto-sync detection and sync processing function.
The Philips P83Cx80; P87C380 are monitor microcontrollers based on the 80C51 family. They include an on-chip oscillator with a maximum frequency of 16 MHz and support various DDC protocols including DDC1, DDC2B, DDC2B+, and DDC2AB (ACCESS.bus).
Key features include automatic mode detection for HSYNC and VSYNC frequencies and polarity, as well as an on-chip sync processor for composite sync separation. The devices offer multiple analog outputs via a 4-bit DAC and digital control through ten 8-bit PWM outputs plus one 14-bit PWM output.
