4. Pin Descriptions
Pin Name I/O Descriptions
P68 I
8080/6800 MCU Interface mode selection.
P68=’1’: select 6800-MCU parallel interface
P68=’0’: select 8080-MCU parallel interface
If not used, please fix this pin at GND level.
IM2 I
MCU Parallel interface bus and Serial interface select
IM2=’1’;Parallel Interface
IM2=’0’;Serial Interface
IM1, IM0 I
MCU parallel interface type selection
IM1 IM0 Parallel interface
0 0 MCU 8-bit Parallel
0 1 MCU 16-bit Parallel
1 0 MCU 9-bit Parallel
1 1 MCU 18-bit Parallel
SPI4W I
SPI interface selection pin
SPI4W=’0’: 3-wire SPI. (default)
SPI4W=’1’: 4-wire SPI.
This pin is internal pull low.
RESX I
Chip reset pin (“Low Active”).
This signal low will reset the device and must be applied to properly initialize the
chip.
CSX I
Chip select input pin (“Low” enable).
This pin can be permanently fixed “Low” in MCU interface mode only.
D/CX
(SCL)
I
Display data / Command selection pin in parallel and SCL in 3-pin SPI interface.
D/CX=’1’: Display data.
D/CX=’0’: Command data.
If not used, please connect this pin to GND.
RDX
(E)
I
Read enable in 8080-parallel interface and Read/ Write operation enable pin in
6800-parallel interface.
In 8080-parallel interface, if not used, please connect this pin to VDDI.
In 6800-parallel interface, if not used, please connect this pin to VDDI or GND.
WRX
(R/WX)(D/CX)
I
Write enable in parallel interface.
WRX: for 8080 MCU
R/WX: for 6800 MCU
D/CX: for 4-wire SPI
If not used, please connect this pin to VDDI or GND.
D[17:1]
D[0]/SDIO
I/O
When RCM1=’0’ (MCU I/F), D[17:0] are used to MCU parallel interface data bus,
and D0 is also the serial input/ output signal in SPI interface mode. In serial
interface, D[17:1] are not used and should be connected to ground.
When RCM1=’1’ (RGB I/F), D[17:0] are used to RGB interface data bus.
