Description

The S3C72H8 single-chip CMOS microcontroller has been designed for very high performance using Samsung's state-of-the-art 4-bit product development approach, SAM47 (Samsung Arrangeable Microcontrollers). Its main features are an up-to-13-digit LCD direct drive capability, 2-channel comparator inputs and outputs, and versatile 8-counter/ timers and 16-bit frequency counter. The S3C72H8 gives you an excellent design solution for a variety of LCD-related applications, specially thermostat control application.

Up to 21 pins of the available 64-pin QFP packages of S3C72H8 can be dedicated to I/O. And six vectored interrupts provide fast response to internal and external events.

In addition, the S3C72H8's advanced CMOS technology provides for low power consumption and a wide operating  voltage range.
