UPD75117H Datasheet (NEC) - 4-BIT SINGLE-CHIP MICROCOMPUTER

UPD75117H, 4-BIT SINGLE-CHIP MICROCOMPUTER

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-volta
