A-1-2 Basic Connection of Parallel I/F
A-1-3 Other Application for FPC
Figure A-3 is an example for RA8816 COG die that connect to FPC for basic parallel interface.
The Figure A-4 is another example that uses 3-wires MPU I/F, 3-times VDD, internal RC Oscillator,
EL driving, 2 I/O signals and 2x2 Key-scan. In this case, the FPC only uses 27pins. Some
configure pin are connect to VDD or GND through ITO resistance, such as C86, BIT4, P/ S ,
CLK_SEL and EXT_CLK. The unused parallel signals of MPU and KIN have to tie to VDD.
The RA8816 also provides two common outputs for Icon that let the panel layout easier to meet
their application.
The pad number 75, 76, 120, 121, 122, 123 are VDD or GND. Their purposes are used to pull-up
or pull-down for some signals on panel. They do not need to connect to FPC.
