OVERVIEW
PRODUCT OVERVIEW
The KS57C4104/KS57C4204/KS57C4304 single-chip CMOS microcontroller has been designed for very high
performance using Samsung's 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/KS57C4304's 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 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.
