Description

The KS57C21632 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).

With an up-to-896-dot LCD direct drive capability, and flexible 8-bit timer/counters, the KS57C21632 offers an excellent design solution for a high-end LCD game.

Up to 12 pins of the 100-pin QFP package can be dedicated to I/O. Seven vectored interrupts provide fast response to internal and external events. In addition, the KS57C21632's advanced CMOS technology provides for low power consumption.
