µPD78F9116B, 78F9116B(A)
8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD78F9116B is a µPD789114A Subseries product of the 78K/0S Series.
The µPD78F9116B replaces the internal ROM of the µPD789111A,789112A and 789114A with flash memory, which
enables the writing/erasing of a program while the device is mounted on the board.
A stricter quality assurance program (called special grade in NEC’s grade classification) is applied to the
µPD78F9116B(A), compared to the µPD78F9116B, which are classified as standard grade.
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 evaluation stages of system development, small-scale production, and rapid
development of new products.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
