S3C72H8

S3C72H8/P72H8 PRODUCT OVERVIEW 1 OVERVIEW PRODUCT OVERVIEW 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 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. 1-1 PRODUCT OVERVIEW S3C72H8/P72H8 FEATURES Architecture – SAM47 4-bit CPU core LCD Controller/Driver – – – – 26 segment and 4 common terminals Maximum 13-digit LCD direct drive capability Display modes: Static, 1/2, 1/3, 1/4 duty Voltage regulator and booster (1/3 bias: 1, 2, or 3V, 1/2 bias: 1.5, 3V) Memory – – Data Memory: 512 × 4 bits Program Memory: 8196 × 8 bits (Including LCD display RAM) Memory-Mapped I/O Structure – Data memory bank 15 Analog Comparator – 2 Ch Comparator (Each CnP, CnN, CnOUT pins) Interrupts – – – Three internal vectored interrupts Three external vectored interrupts Two quasi-interrupts Bit Sequentia...
