KS57P5532 Overview
KS57C5532/P5532 PRODUCT OVERVIEW 1 PRODUCT OVERVIEW OVERVIEW 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...
