DATA SHEET
MOS INTEGRATED CIRCUIT
µPD75004, 75006, 75008
4-BIT SINGLE-CHIP MICROCOMPUTER
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.
Detailed functions are described in the following user’s manual. Be sure to read it for designing.
µPD7500X Series User’s Manual: IEM-5033
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.
Unless otherwise specified, µPD75008 is treated as the representative model throughout this manual.

To connect the crystal/ceramic oscillator to the
main system clock generator. When inputting the
external clock, input the external clock to pin X1,
and the reverse phase of the external clock to pin
X2.
To connect the crystal oscillator to the subsystem
clock generator.
When the external clock is used, pin XT1 inputs
the external clock. In this case, pin XT2 must be
left open.
