S3C72C8

S3C72C8/P72C8 PRODUCT OVERVIEW 1 OVERVIEW PRODUCT OVERVIEW The S3C72C8 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 S3C72C8 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 S3C72C8's advanced CMOS technology provides for low power consumption. OTP The S3C72C8 microcontroller is also available in OTP (One Time Programmable) version, S3P72C8. S3P72C8 microcontroller has an on-chip 8K-byte one-time-programable EPROM instead of masked ROM. The S3P72C8 is comparable to S3C72C8, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW S3C72C8/P72C8 FEATURES Memory 512 × 4-bit RAM (including LCD display RAM) 8,192 × 8-bit ROM Interrupts Four internal vectored interrupts Five external vectored interrupts Two quasi-interrupts 28 I/O Pins I/O: 26 pins (44-pin QFP, 42-pin SDIP) Output only: 2 pins (44-pin QFP) Bit Sequential Carrier Supports 16-bit serial data transfer in arbitrary format LCD Controller/Driver 12 segments and 8 common terminals (3, 4, and 8 common selectable) Internal resistor circuit for LCD bias ...
