Description

The S3P72C8 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-96-dot LCD direct drive capability flexible 16-bit timer/counter, and 4-chanel comparator, the S3P72C8 offers an excellent design solution for a low CDP and a card reader.

Up to 28 pins of the 44-pin QFP or up to 26 pins of the 42-pin SDIP package can be dedicated to I/O. Eight vectored interrupts provide fast response to internal and external events. In addition, the S3P72C8's advanced CMOS technology provides for low power consumption.
