The D78F9177 is an 8-BIT SINGLE-CHIP MICROCONTROLLER made by NEC, supplied in a QFP 44 Pin Type package. The absolute maximum ratings table on this page lists the 7 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the D78F9177 maximum ratings, with the full datasheet PDF to preview below or download.
The mPD78F9177 and mPD78F9177Y are mPD789177, 789177Y Subseries (small, general-purpose) in the 78K/0S Series.
The mPD78F9177 replaces the internal ROM of the mPD789176 and mPD789177 with flash memory, while the
mPD78F9177Y replaces the ROM of the mPD789176Y and mPD789177Y 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.
Pin compatible with mask ROM version (except VPP pin)
Flash memory: 24 Kbytes
