S MSUNG KS57C2408A/2416A 4-BIT CMOS Microcontroller www.datasheet4u.com Product Specification OVERVIEW The KS57C2408A/2416A single-chip CMOS microcontroller is designed for very high performance using Samsung's newest 4-bit product development approach, SAM4 (Samsung Arrangeable Microcontrollers). Its main features are an up-to-12-digit LCD direct drive capability, 8-bit × 6-channel A/D converter, and versatile 8-bit and 16-bit counter/ timers. The "2408A/2416A" gives you an excellent design solution for a variety of LCD-related applications. Up to 50 pins of the available 80-pin QFP packages can be dedicated to I/O. And eight vectored interrupts provide fast response to internal and external events. In addition, the 2408A/2416A's advanced CMOS technology ensures low power consumption and a wide operating voltage range.
