UPD75117H

DATA SHEET MOS INTEGRATED CIRCUIT µPD75116H,75117H 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75117H is a 75X Series 4-bit single-chip microcomputer. The µPD75117H is a product which has the same functions as those of the µPD751××F, with the minimum operating voltage reduced from the previous 2.7 V to 1.8 V, and achieving 1.91 µs operation at 1.8 V. Therefore, it facilitates low-voltage operation for a set requiring high-speed operation. Functions are described in detail in the following User’s Manual, which should be read when carrying out design work. µPD75117H User’s Manual : IEU-799 FEATURES Memory capacity ROM : 24448 × 8 bits (µPD75117H) : 16256 × 8 bits (µPD75116H) RAM : 768 × 4 bits High-speed low voltage operation Minimum instruction execution time : Operating voltage range Input/output ports : 58 Timer/counter : 3 channels Timer/event counter × 2 channels Basic interval timer × 1 channel 8-bit serial interface on chip Programmable threshold port On-chip PROM product available : 1.91 µs (VDD = 1.8 V) 0.95 µs (VDD = 2.7 V) 1.8 to 5.5 V (Ta = –40 to +60 °C) 5 : : 4-bit resolution × 4 channels µPD75P117H (One-time PROM) APPLICATIONS Cordless telephone subsets, portable radio equipment, pager, etc. "Unless there are any particular functional differences, the µ PD75117H is described in this document as a representative product."
