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. With its internally provided A/D converter and serial interfa.
• 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
· 8-bit timer/event counter
