S3C8625/C8627/C8629/P8629 single-chip 8-bit microcontrollers are based on the powerful SAM8 CPU architecture. The internal register file is logically expanded to increase the on-chip register space. S3C8625/C8627/C8629/P8629 contain 16/32 K bytes of on-chip program ROM. In line with Samsungs modular design approach, the following peripherals are integrated with the SAM8 core:

— Four programmable I/O ports (total 27 pins)

— One 8-bit basic timer for oscillation stabilization and watchdog functions

— One 8-bit general-purpose timer/counter with selectable clock sources

— One 12-bit counter with selectable clock sources, including Hsync or Csync input

— One interval timer

— PWM block with seven 8-bit PWM circuits

— Sync processor block (for Vsync and Hsync I/O, Csync input, and Clamp signal output)

— DDC and normal Multi-master IIC-bus

— 4-channel A/D converter (8-bit resolution)
