DATA SHEET www.DataSheet4U.com MOS INTEGRATED CIRCUITS 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. µPD789104A, 789114A, 789124A, 789134A Subseries User’s Manual: U14643E 78K/0S Series User’s Manual Instruction: U11047E FEATURES Pin-compatible with mask ROM version (excluding VPP pin) Flash memory: On-chip multiplier: 16 KB Internal high-speed RAM: 256 bytes 8 bits × 8 bits = 16 bits Minimum instruction execution time can be changed from high-speed (0.2 µs) to low-speed (0.8 µs) (@ 10.0 MHz operation with system clock, VDD = 4.5 to 5.5 V) I/O ports: 20 Serial interface: 1 channel: Switchable between 3-wire serial I/O and UART mo...
