UPD75116F - NEC

UPD75116F 4-BIT SINGLE-CHIP MICROCOMPUTER

The µPD75116F offers high-speed operation (tCY = 1.91 µ s) at a low supply voltage (VDD = 2.7 V) which is not possible with the µPD75116. It has the same functions as, and is pin compatible with, the µPD75116, allowing low voltage sets to be developed by making efficient use of previously developed and used software resources. Note, however, that the operati.
