DATA SHEET MOS INTEGRATED CIRCUITS PD78F9116B, 78F9116B(A) 8-BIT SINGLE-CHIP MICROCONTROLLERS DESCRIPTION The PD78F9116B is a PD789114A Subseries product of the 78K/0S Series. The PD78F9116B replaces the internal ROM of the PD789111A,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 NECs grade classification) is applied to the PD78F9116B(A), compared to the PD78F9116B, 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 users manuals. Be sure to read them before designing.
