Description
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.
Features
- 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).
