Description

The KS57C5532/P5532 single-chip CMOS microcontroller has been designed for high-performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). The KS57P5532 is a microcontroller which has 32-kbyte one-time-programmable EPROM but its functions are same to KS57C5532.

With its DTMF generator, 8-bit serial I/O interface, and versatile 8-bit timer/counters, the KS57C5532/P5532 offers an excellent design solution for a wide variety of telecommunication applications.

Up to 55 pins of the 64-pin SDIP or QFP package can be dedicated to I/O. Seven vectored interrupts provide fast esponse to internal and external events. In addition, the KS57C5532/P5532's advanced CMOS technology provides for low power consumption and a wide operating voltage range.
