5. μ-Controller Chip On-board writing system
The LC87F33C8A 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 has to connect the 6 pins (communication (CLK, DATA × 2), power supply (CpuVDD, CpuGND) and RES#, 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.
Please ask to our sales persons before using On-board writing system.
