Overview

  • Higher reliable than the µPD75517 Capacities of program memory, ROM: 24448 × 8 bits Capacity of data memory, RAM: 1024 × 4 bits Function for specifying the instruction execution time (useful for high-speed operation and saving power)
  • 0.67 µs/1.33 µs/2.67 µs/10.7 µ s (when the main system clock operates at 6.0 MHz)
  • 0.95 µs/1.91 µs/3.82 µ s/15.3 µs (when the main system clock operates at 4.19 MHz)
  • 122 µs (when the subsystem clock operates at 32.768 kHz)
  • Built-in A/D converter operable on low voltage
  • 8-bit resolution × 8 channels (Successive approximation system)
  • VDD = 2.7 to 6.0 V
  • Many I/O lines: 64
  • Enhanced timer function: 4 channels
  • Built-in 8-bit serial interface: Two channels
