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)
