OVERVIEW
PRODUCT OVERVIEW
The KS57C5616/P5616 single-chip CMOS microcontroller is designed for high performance in the application for Caller-ID, Telephone using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangable Microcontrollers). Featuring a DTMF generator, up-to-960-dot LCD direct drive capability, one 8-bit timer/counter and flexible two 8-bit timer/counters, and serial I/O interface, the KS57C5616/P5616 offer an excellent design solution for a wide variety of applications requiring DTMF, LCD support. Up to 43 (including COM/SEG) pins in the 100-pin QFP package can be dedicated to I/O. Nine vectored interrupts provide a fast response to internal and external events. In addition the advanced CMOS technology a of the KS57C5616/P5616 ensures low power consumption with a wide operating voltage range.
OTP
The KS57C5616 microcontroller is also available in OTP (One Time Programmable) version, KS57P5616. KS57P5616 microcontroller has an on-chip 16K-byte one-time-programmable EPROM instead of masked ROM. The KS57P5616 is comparable to KS57C5616, both in function and in pin configuration.

OVERVIEW
KS57P5616 OTP
The KS57P5616 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the KS57C5616 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data format. The KS57P5616 is fully compatible with the KS57C5616, both in function and in pin configuration. Because of its simple programming requirements, the KS57P5616 is ideal for use as an evaluation chip for the KS57C5616.
