78F9177 Datasheet Upd78f9177

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET µPD78F9177, 78F9177Y 8-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED CIRCUIT The µPD78F9177 and µPD78F9177Y are µPD789177, 789177Y Subseries (small, general-purpose) in the 78K/0S Series. The µPD78F9177 replaces the internal ROM of the µPD789176 and µPD789177 with flash memory, while the µPD78F9177Y replaces the ROM of the µPD789176Y and µPD789177Y with flash memory. Because flash memory allows the program to be written and erased electrically with the device mounted on the board, this product is ideal for the evolution stages of system development, small-scale production and rapid development of new products.

General Description

s are provided in the following user’s manuals.

Be sure to read them before designing.
