Description

The S3P7414 single-chip CMOS microcontroller has been designed for very high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontroller).

With an A/D converter, LED direct drive pins, an 8-bit serial I/O interface, and an 8-bit timer/counter, the S3P7414 offers you an excellent design solution for a wide variety of home appliance applications - electric fans, cookers, boilers, and air conditioners, for example.

Up to 35 pins of the 42-pin SDIP or 44-pin QFP package can be dedicated to I/O. Seven vectored interrupts of S3P7414 provide fast response to internal and external events.

In addition, the S3P7414's advanced CMOS technology provides for low power consumption and a wide operating voltage range.
