Features, Applications

The S3C72P9 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, flexible 8-bit and 16-bit timer/counters, and serial I/O interface, the S3C72P9 offers an excellent design solution for a wide variety of applications which require LCD functions. 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 S3C72P9's advanced CMOS technology provides for low power consumption and a wide operating voltage range. The S3C72P9 is made by shrinking the KS57C21516. The S3C72P9 is comparable to KS57C21516, both in function and in pin configuration except that S3C72P9 have 32,768 8-bit ROM, 10564-bit RAM, 12 common selectable and LCD contrast control function.

The S3C72P9 microcontroller is also available in OTP (One Time Programmable) version, S3P72P9. S3P72P9 microcontroller has an on-chip 32K-byte one-time-programmable EPROM instead of masked ROM. The S3P72P9 is comparable to S3C72P9, both in function and in pin configuration.
