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 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/P5532's 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 develop-
ment 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.
