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 µ s minimum instruction execution time for the CPU, the µ PD75008 employs a serial bus interface with standard NEC format, the µPD75004 is a powerful product with a high cost/performance ratio. The µ PD75P008 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 architec [ … ]
