General Description
KS88C8432 General Description
The KS88C8424 microcontroller has a 24-Kbyte on-chip program memory and the KS88C8432 has a 32-Kbyte. Both chips have a 272-byte general-purpose internal register file. The interrupt structure has nine interrupt sources with nine interrupt vectors. The CPU recognizes seven interrupt priority levels.
Using a modular design approach, the following peripherals were integrated with the SAM87 core to make the KS88C8424/C8432/P8432 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)
- 4-bit resolution A/D converter (4 channels)
- 14-bit PWM output (Two channels: push-pull type, open-drain type)
- Basic timer (BT) with watchdog timer function
- One 8-bit timer/counter (T0) with interval timer and PWM mode
- One 8-bit general-purpose timer/counter (TA) with prescalers
- On-screen display (OSD) with a wide range of programmable features, including halftone control signal output
The KS88C8424 and the KS88C8432 are available in versatile 42-pin SDIP package.
