OVERVIEW
The KS57C5532/P5532 single-chip CMOS microcontroller has been designed for high-performance using Samsungs 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 response to internal and external events. In addition, the KS57C5532/P5532s advanced CMOS technology provides for low power consumption and a wide operating voltage range.

DEVELOPMENT SUPPORT
The Samsung Microcontroller Development System, SMDS, provides you with a complete PC-based development environment for KS57-series microcontrollers that is powerful, reliable, and portable. In addition to its window-based program development structure, the SMDS toolset includes versatile debugging, trace, instruction timing, and performance measurement applications.
The Samsung Generalized Assembler (SAMA) has been designed specifically for the SMDS environment and accepts assembly language sources in a variety of microprocessor formats. SAMA generates industry-standard hex files that also contain program control data for SMDS compatibility.
