S3P7565

S3C7565/P7565 PRODUCT OVERVIEW 1 OVERVIEW PRODUCT OVERVIEW The S3C7565/P7565 single-chip CMOS microcontroller is designed for high performance in the application for Caller-ID, Telephone using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangable Microcontrollers). Featuring a DTMF generator, up-to-960-dot LCD direct drive capability, one 8-bit timer/counter and flexible two 8-bit timer/counters, and serial I/O interface, the S3C7565/P7565 offer an excellent design solution for a wide variety of applications requiring DTMF, LCD support. Up to 43 (including COM/SEG) pins in the 100-pin QFP package can be dedicated to I/O. Nine vectored interrupts provide a fast response to internal and external events. In addition the advanced CMOS technology a of the S3C7565/P7565 ensures low power consumption with a wide operating voltage range. OTP The S3C7565 microcontroller is also available in OTP (One Time Programmable) version, S3P7565. S3P7565 microcontroller has an on-chip 16 K-byte one-time-programmable EPROM instead of masked ROM. The S3P7565 is comparable to S3C7565, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW S3C7565/P7565 FEATURES SUMMARY Memory 16K × 8-bit ROM 5,120 × 4-bit RAM (excluding LCD RAM) 8-bit Serial I/O Interface 8-bit transmit/receive mode 8-bit receive mode LSB-first or MSB-first transmission selectable I/O Pins Input only: 4pins (Not including COM/SEG) 6pins (Including COM/SEG) I/O: 15pins (Not including COM/SEG) 43...
