µPD75518(A)
4 BIT SINGLE-CHIP MICROCOMPUTER
The µPD75518(A) is a 75X series four-bit single-chip microcomputer which enables data processing
equivalent to that performed by an eight-bit microcomputer. It is a high-performance product, whose
minimum instruction execution time is 0.67 µs, shorter than 0.95 µs for the conventional µPD75516. The ROM
and RAM capacities are also larger, and the throughput of the 75X series is further increased. The µPD75517(A)
www.DataSheiest4sUu.citoemd to controllers of electric parts of automobiles.
FEATURES
Higher reliable than the µPD75518
Capacities of program memory, ROM: 32640 × 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 µs (when the main system clock operates at 6.0 MHz)
• 0.95 µs/1.91 µs/3.82 µs/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
• Built-in NEC serial bus interface (SBI)
Clock operable with ultra-low power consumption (when 5-µA TYP. operates on 3 V.)
Product with a built-in PROM available: µPD75P518
APPLICATIONS
Controller of electric parts of automobiles
