LCD MODULE DT032TFT / DT032TFT-TS Version: 3.0
LED Backlight Anode
LED Backlight Cathode
Ground
Power supply
When using the RGB interface, it is a input pin put the driver into sleep mode. A
sharp falling edge must be provided to such pin when IC power on.
Connect to VDDIO for sleep mode
Connect to VSS for normal operating mode
This pin has no effect in system interface and should be connected to VDDIO / VSS
Reset signal pin
Frame synchronization signal.
- Fixed to VDDIO or VSS if not used
Line synchronization signal.
- Fixed to VDDIO or VSS if not used
Dot-clock signal and oscillator source. A non-stop external clock must be provided
to that pin even at front or black porch non-display period.
Display enable pin from controller. Data will be treated as dummy regardless the
DEN status during front/back porch setting at registers R16 and R17.
Data bus
68 system: Enable (E)
80 system: Read signal (/RD)
Serial: Not used
68 system: Read when high, Write when low (/WR)
80 system: Write signal (WR)
Serial: Not used
