LC86F3G64A
On-board writing system
The LC86F3G64A has the On-board writing system. The program is renewable by using SANYO Flash On-board
System after the LSI has been installed on the application board.
This system is composed of 4 types divided by the combination of the mode setting pin and communication pin.
Each type system has to connect the 6 pins (VDD, VSS, RES, communication pins) with the interface board of SANYO
Flash On-board System.
It is necessary that the pins to be used for the rewriting system should be able to be separated from the application board
properly.
The system type is selected by the option setting program (Su86K.exe).

• Type 3 or 4 is selected: P00 is exclusive for the on-board system.
This pin must always be pulled-down, so this pin can’t be used for other applications.
Please set P00 pin N-channel open drain output.(option setting)
In the user program, “0” is always set to the P00 latch (bit 0 in the Port 0 latch (140h)) because
the P0 interrupt must not be requested on the P00 pin .
• The loader program must be written into the ROM to use On-board writing system.
The loader program should be written into the ROM before the LSI has been installed on the board by the general
purpose PROM programs.
When the option setting selects the this system to use, the loader program automatically links to the extended ROM
field (14000h-147FFh) on the user program linking.
Please ask to our sales persons before using On-board writing system.
