OVERVIEW
The KS57C5404 single-chip CMOS microcontroller is designed for high-performance using Samsung’s newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).
With a versatile 8-bit timer/counter and a D/A converter, the KS57C5404 offers an excellent design solution for a wide variety of telecommunication applications.
Up to 17 pins of the 24-pin SDIP package can be dedicated to I/O. Four vectored interrupts provide fast response to internal and external events. In addition, the KS57C5404’s advanced CMOS technology has realized substantially lower power consumption with a wide operating voltage range — all at a substantially lower cost.
OTP
The KS57C5404 microcontroller is also available in OTP (One Time Programmable) version, KS57P5404. KS57P5404 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The KS57P5404 is comparable to KS57C5404, both in function and in pin configuration.
