OVERVIEW
The KS57C4104/KS57C4204/KS57C4304 single-chip CMOS microcontroller has been designed for very high performance using Samsungs newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontroller).
With an A/D converter, LED direct drive pins, an 8-bit serial I/O interface, and an 8-bit timer/counter, the KS57C4104/KS57C4204/KS57C4304 offers you an excellent design solution for a wide variety of home appliance applications — electric fans, cookers, boilers, and air conditioners, for example.
Up to 35 pins of the 42-pin SDIP or 44-pin QFP package can be dedicated to I/O. Seven vectored interrupts provide fast response to internal and external events.
In addition, the KS57C4104/KS57C4204/KS57C4304s advanced CMOS technology provides for low power consumption and a wide operating voltage range.

OTP
The KS57C4104/KS57C4204/KS57C4304 microcontroller is also available in OTP (One Time Programmable) version, KS57P4104/KS57P4204/KS57P4304. KS57P4104/KS57P4204/KS57P4304 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The KS57P4104/KS57P4204/KS57P4304 is comparable to KS57C4104/KS57C4204/KS57C4304, in function, in D.C. electrical characteristics and in pin configuration.

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.
