S3C72I9

S3C72I9/P72I9 PRODUCT OVERVIEW 1 OVERVIEW PRODUCT OVERVIEW The S3C72I9 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-896-dot LCD direct drive capability, 8-bit timer/counter 0, 16-bit timer/counter 1, and serial I/O, the S3C72I9 offers an excellent design solution for a wide variety of applications which require LCD functions. Up to 39 pins of the 100-pin QFP package can be dedicated to I/O. Eight vectored interrupts provide fast response to internal and external events. In addition, the S3C72I9's advanced CMOS technology provides for low power consumption and a wide operating voltage range. OTP The S3C72I9 microcontroller is also available in OTP (One Time Programmable) version, S3P72I9. S3P72I9 microcontroller has an on-chip 32 K-byte one-time-programable EPROM instead of masked ROM. The S3P72I9 is comparable to S3C72I9, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW S3C72I9/P72I9 FEATURES SUMMARY Memory 8,192 × 4-bit RAM (excluding LCD display RAM) 32,768 × 8-bit ROM 39 I/O Pins I/O: 35 pins Input only: 4 pins Interrupts LCD Controller/Driver 56 segments and 16 common terminals 8 and 16 common selectable Internal resistor circuit for LCD bias All dot can be switched on/off Bit Sequential Carrier Supports 16-bit serial data transfer in arbitrary format Four internal vectored interrupts Four external ...
