LCD MODULE DT028TFT / DT028TFT-TS Version: 5.0
Reset signal pin
Frame synchronous signal for RGB interface operation. Low active.
Line synchronous signal for RGB interface operation. Low active.
Dot clock signal for RGB interface operation. The data input timing is on the rising
edge of DOTCLK.
Data enable signal for RGB interface operation.
Data bus
Serial data output (SDO) pin in serial interface operation. The data is outputted on the
falling edge of the SCL signal.
Serial data input (SDI) pin in serial interface operation. The data is inputted on the
rising edge of the SCL signal.
Read strobe signal in 80-system bus interface operation and enables read operation
when RD* is low.
Write strobe signal in 80-system bus interface operation and enables write operation
when WR* is low. Synchronous clock signal (SCL) in serial interface operation.
Register select signal
Chip select signal
Frame head pulse signal, which is used when writing data to the internal RAM.
