UPD75117H Description
The µPD75117H is a 75X Series 4-bit single-chip microputer. 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.
