符号 | I/O | 功能说明 | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | VSS | P | Ground. | ||||||||||
| 2 | VDD | P | Power Supply for Core Logic Circuit Power supply pin for core logic operation. A capacitor is required to connect between this pin and VSS |
||||||||||
| 3 | N.C. | P | Reserved Pin The N.C. pin between function pins are reserved for compatible and flexible design. |
||||||||||
| 4 | D/C# | I | Data/Command Control This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the content at D[7:0] will be interpreted as data. When the pin is pulled LOW, the content at D[7:0] will be interpreted as command. |
||||||||||
| 5 | R/W# (WR#) |
I | Read/Write Select or Write This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it to “Low” for write mode. When 80XX interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled low and the CS# is pulled low. When serial mode is selected, this pin must be connected to VSS. |
||||||||||
| 6 | E/RD# | I | Read/Write Enable or Read This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low. When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low. When serial mode is selected, this pin must be connected to VSS. |
||||||||||
| 7~14 | DB0 | I/O | Host Data Input/Output Bus These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial mode is selected, DB1 will be the serial data input SDIN and DB0 will be the serial clock input SCLK. |

| 16 | RES# | I | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. |
||||||||||
| 17 | CS# | I | Data/Command Control This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW. |
