S3P7048

S3C7044/C7048/P7048 PRODUCT OVERVIEW 1 PRODUCT OVERVIEW The S3C7044/C7048 single-chip CMOS microcontroller has been designed for very high-performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). The S3P7048 is the microcontroller which has 8K-bytes one-time-programmable ROM and the functions are same to S3C7044/C7048. With two 8-bit timer/counters, an 8-bit serial I/O interface, and eight software n-channel open-drain I/O pins, the S3C7044/C7048 offers an excellent design solution for a wide variety of general-purpose applications. Up to 36 pins of the 42-pin SDIP or 44-pin QFP package can be dedicated to I/O. Seven vectored interrupts provide fast response to internal and external events. In addition, the S3C7044/C7048's advanced CMOS technology provides for low power consumption and a wide operating voltage range. 1-1 PRODUCT OVERVIEW S3C7044/C7048/P7048 FEATURES SUMMARY Memory 512 × 4-bit RAM 4096 × 8-bit ROM: S3C7044 8192 × 8-bit ROM: S3C7048 Bit Sequential Carrier Supports 16-bit serial data transfer in arbitrary format Interrupts 3 external interrupt vectors 4 internal interrupt vectors 2 quasi-interrupts 36 I/O Pins Input only: 4 pins I/O: 24 pins N-channel open-drain I/O: 8 pins Power-Down Modes Idle: Only CPU clock stops Stop: System clock stops Memory-Mapped I/O Structure Data memory bank 15 8-Bit Basic Timer 4 interval timer functions Oscillation Sources Crystal or Ceramic for ...
