Description

The S3C880A/S3F880A microcontroller has 48-Kbytes of on-chip program memory. This chips have a 336-byte generalpurpose internal register file. The interrupt structure has 9 interrupt sources with 9 interrupt vectors. The CPU recognizes seven interrupt priority levels.

Using a modular design approach, the following peripherals were integrated with the SAM88LP core to make the S3C880A/S3F880A microcontrollers suitable for use in color television and other types of screen display applications:

- Four programmable I/O ports (26 pins total: 16 general-purpose I/O pins; 10 n-channel, open-drain output pins)
- Four Channel A/D converter (8-bit resolution)
- Two 14-bit PWM output and four 8-bit PWM output.
- Basic timer (BT) with watchdog timer function
- One 8-bit general-purpose timer/counter (T0) with interval timer Mode and PWM Output Mode
- One 8-bit timer/counters (TA) with prescalers and interval timer mode
- On-screen display (OSD) with a wide range of programmable features, including halftone control signal output

The S3C880A/S3F880A is available in a versatile 42-pin SDIP, 44-pin QFP package.
