KS57C3204/P3204 PRODUCT OVERVIEW
1 PRODUCT OVERVIEW
OVERVIEW
The KS57C3204 single-chip CMOS microcontroller has been designed for high performance using Samsung's
newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).
With features such as LCD direct drive capability, 4-channel A/D converter, 24-bit AM/FM frequency counter and
watch timer, the KS57C3204 offers an excellent design solution for a wide variety of applications that require
LCD functions and audio applications.
Up to 32 pins of the 64-pin QFP package, it can be dedicated to I/O. Five vectored interrupts provide fast
response to internal and external events. In addition, the KS57C3204 's advanced CMOS technology provides for
low power consumption and a wide operating voltage range.
OTP
The KS57C3204 microcontroller is also available in OTP (One Time Programmable) version, KS57P3204 . The
KS57P3204 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM.
The KS57P3204 is comparable to KS57C3204, both in function and in pin configuration.

OVERVIEW
The KS57P3204 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the
KS57C3204microcontroller. It has an on-chip EPROM instead of masked ROM. The EPROM is accessed by a
serial data format.
The KS57P3204 is fully compatible with the KS57C3204, both in function and in pin configuration. Because of its
simple programming requirements, the KS57P3204 is ideal for use as an evaluation chip for the KS57C3204.
