MOS INTEGRATED CIRCUIT
µPD78F9177, 78F9177Y
8-BIT SINGLE-CHIP MICROCONTROLLER
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.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.

Cautions 1. Connect the VPP pin directly to the VSS0 or VSS1 pin in normal operation mode.
2. Connect the IC0 (Internally Connected) pin directly to VSS0 or VSS1.
3. Leave the IC2 pin open.
4. Connect the AVDD pin to VDD0.
5. Connect the AVSS pin to VSS0.

5. FLASH MEMORY PROGRAMMING
The on-chip program memory in the µPD78F9177 and µPD78F9177Y is flash memory.
The flash memory can be written with the µPD78F9177 and µPD78F9177Y mounted on the target system (on-
board). Connect the dedicated flash programmer (Flashpro III (part number: FL-PR3, PG-FP3)) to the host machine
and target system to write the flash memory.
Remark FL-PR3 is made by Naito Densei Machida Mfg. Co., Ltd.
5.1 Selecting Communication Mode
The flash memory is written by using Flashpro III and by means of serial communication. Select a communication
mode from those listed in Table 5-1. To select a communication mode, the format shown in Figure 5-1 is used. Each
communication mode is selected by the number of VPP pulses shown in Table 5-1.
