OVERVIEW
The KS57C2302/C2304 single-chip CMOS microcontroller has been designed for high performance using Samsungs newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).
With features such as, LCD direct drive capability, 8-bit timer/counter, and watch timer, the KS57C2302/C2304 offers an excellent design solution for a wide variety of applications that require LCD functions.
Up to 16 pins of the 64-pin QFP package, it can be dedicated to I/O. Four vectored interrupts provide fast response to internal and external events. In addition, the KS57C2302/C2304 s advanced CMOS technology provides for low power consumption and a wide operating voltage range.

OTP
The KS57C2302/C2304 microcontroller is also available in OTP (One Time Programmable) version, KS57P2304 . The KS57P2304 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The KS57P2304 is comparable to KS57C2302/C2304, both in function and in pin configuration.
