User Interface

LCD module

Maxwell is using a 130 * 130 dot LCD display with 4096 colors. The illumination is inte-
grated into the LCD module.
Baseband LCD interface
The LCD display is connected to the transceiver PWB by 10-pin board-to-board connec-
tor.
DC characteristics
Display is using 3-wire serial interface. Signals for LCD panel are shown in table below.
The chip-select XCS (active low) enables and disables the serial interface. RESX (active
low) is external reset signal. The SCL is serial data clock. SI data-length is 8 bits + D/C-
bit. First bit is D/C-bit which indicates the status of following 8 bit data. In case of com-
mand data D/C-bit is low ('0'). VDDI is logic voltage supply for the display. VDD is supply
voltage for high voltage generation. GND is system ground for display.
