S3P72F5 Datasheet | Samsung Semiconductor

OVERVIEW PRODUCT OVERVIEW OVERVIEW The S3C72F5 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 and 16-bit timer/counter, and serial I/O, the S3C72F5 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 S3C72F5's advanced CMOS technology provides for low power consumption and a wide operating voltage range. The S3C72F5 microcontroller is also available in OTP (One Time Programmable) version, S3P72F5. S3P72F5 microcontroller has an on-chip 16K-byte one-time-programable EPROM instead of masked ROM. The S3P72F5 is parable to S3C72F5, both in function and in pin configuration.
