UPD75004中文资料瑞萨数据手册PDF规格书

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

• Capable of high-speed operation and variable instruction execution time to power save

• 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.
