20-Pin Parallel Interface
The modules use an 8-bit bidirectional data bus. Review the exact datasheet pin table and timing limits before PCB release.
Data and Control
DB0-DB7 carry display data, commands, and status. /WR, /RD, /CE, C/D, and /RESET control bus access and controller initialization.
Power and LCD Bias
VDD and VSS provide logic power and ground. VO is the LCD-driver supply/contrast input, while VEE is the negative-voltage output used by the contrast-adjustment circuit.
Font Selection
FS high selects a 6×8 character format; FS low selects an 8×8 character format.
Timing Limits
C/D setup: 100 ns minimum; C/D hold: 10 ns minimum; /CE, /RD, /WR pulse width: 80 ns minimum; data setup: 80 ns minimum; data hold: 40 ns minimum.
Technical Documents
Use the datasheet for the exact selected SKU. The RA6963 controller specification is a separate reference for controller commands, timing, and display-memory operation.
