Description

The KS57C5204single-chip CMOS microcontroller has been designed for highperformance using SAM 47 (Samsung Arrangeable Microcontrollers). SAM 47, Samsung's newest 4-bit CPU core is notable for its low energy consumption and low operating voltage.

You can select from three ROM sizes: 4K, 8K, or 12K bytes.

Except for the difference in ROM size, the features and functions of the KS57C5204 and the KS57C5208 are identical and the KS57C5304, KS57C5308, and the KS57C5312 are identical.

With it's DTMF generator, watchdog timer function, and versatile 8-bit timer/counters, the  S57C5204 offers an excellent design solution for a wide variety of telecommunication applications.

Up to 35 pins of the available 42-pin SDIP or 44-pin QFP package for the KS57C5204/C5208, and up to 23 pins of the available 30-pin SDIP or 32-pin SOP package for the KS57C5304/C5308/C5312 can be assign to I/O. Six ectored interrupts for KS57C5204/C5208 and four vectored interrupts for KS57C5304/C5308/C5312 provide fast esponse to internal and external events. In addition, the KS57C5204advanced CMOS technology provides for low power consumption and a wide operating voltage range.
