DESCRIPTION

The μPD75008 is one of the 75X Series 4-bit single-chip microcomputer.

In addition to high-speed operation with 0.95 μs minimum instruction execution time for the CPU, the μPD75008 employs a serial bus interface with standard NEC format, the μPD75004 is a powerful product with a high cost/performance ratio.

The μPD75P008 with PROM, which is provided with μPD75008, is applicable for evaluating systems under development, or for small-scale production of developed systems.

FEATURES

? 0.95 μs, 1.91 μs, 15.3 μs (Main system clock: operating at 4.19 MHz)

? 122 μs (Subsystem clock: operating at 32.768 kHz)

? 75X architecture comparable to that for an 8-bit microcomputer is employed

? Built-in NEC standard serial bus interface (SBI)

? Clock operation at reduced power dissipation (5 μA TYP. : operating at 3 V)

? Enhanced timer function (3 channels)

? Interrupt functions especially enhanced for applications, such as remote control receiver

APPLICATIONS

VCRs, CD players, telephones, cameras, blood pressure gauges, etc.
