Overview

The µPD75512(A) is a 4-bit single-chip microcomputer which employs 75X series architecture, and its performance is comparable to that of an 8-bit microcomputer. In addition to its high-speed processing capabilities, the µPD75512(A) is also capable of processing data in units of 1, 4, or in 8-bits.

  • Higher reliability than µPD75512
  • Adequate I/O lines: 64 (can be provided with pull-up/pull-down resistors: 47)
  • Built-in 8-bit serial interface: 2-ch NEC standard serial bus interface (SBI) internally provided
  • Built-in 8-bit A/D converter: 8-ch
  • Variable instruction execution time function which is convenient for high-speed operation and power saving
  • 0.95 µs/1.95 µs/15.3 µs (at 4.19 MHz operation),
  • 122 µs (at 32.768 kHz operation)
  • Program memory (ROM) size: 12,160 × 8 bits
  • Data memory (RAM) size: 512 × 4 bits
  • High-performance timer function: 4-ch
