OVERVIEW
PRODUCT OVERVIEW
The KS57C21832 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). With an up-to-896-dot LCD direct drive capability, 8-bit timer/counter 0, 16-bit timer/counter 1, and serial I/O, the KS57C21832 offers an excellent design solution for a wide variety of applications which require LCD functions. Up to 39 pins of the 100-pin QFP package can be dedicated to I/O. Eight vectored interrupts provide fast response to internal and external events. In addition, the KS57C21832's advanced CMOS technology provides for low power consumption and a wide operating voltage range.
OTP
The KS57C21832 microcontroller is also available in OTP (One Time Programmable) version, KS57P21832. KS57P21832 microcontroller has an on-chip 32 K-byte one-time-programable EPROM instead of masked ROM. The KS57P21832 is comparable to KS57C21832, both in function and in pin configuration.

OVERVIEW
KS57P21832 OTP
The KS57P21832 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the KS57C21832 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data format. The KS57P21832 is fully compatible with the KS57C21832, both in function and in pin configuration. Because of its simple programming requirements, the KS57P21832 is ideal for use as an evaluation chip for the KS57C21832.
