| 1 | VDDA | Power Supply (Analog) | ||||||||||||
| 2 | VDDI | Power Supply (Digital) | ||||||||||||
| 3 | GND | Ground | ||||||||||||
| 4 | RSTB | Reset input pin. When RSTB is “L”, internal initialization procedure is executed. | ||||||||||||
| 5 | NC(VPP) | No connect (The programming power supply of the built-in NVM. Apply external power 7.5V here when programming (> 8mA for successful programming). If not used, left this pin open.) |
||||||||||||
| 6 | A0 | When using 8080. It determines whether the access is related to data or command. A0 = "H": Indicates that D[7:0] are display data; A0 = "L": Indicates that D[7:0] are control data. |
||||||||||||
| 7 | NC(WR) | No connect (When using 8080 Write enable in 8080 parallel interface. ) |
||||||||||||
| 8 | NC(RD) | No connect (Read enable in 8080 interface. This pin is not used in serial interfaces and should be connected to VDDI.) |
||||||||||||
| 9 | CSB | Chip select input pin. CSB=“L”: This chip is selected and the MPU interface is active. CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance). |
||||||||||||
| 10 | SCLK(D0) | When using 8-bit parallel interface: 8080 mode 8 bit bi-directional data bus. Connect to the data bus of 8-bit microprocessor. When CSB is “H”, D[7:0] are high impedance. When using serial interface: 4-line SPI, 3-line SPI. D[7:4] : fix to “H” by VDDI. D[3:2] : serial output data (SDA_OUT). D[1] : serial input data (SDA_IN). D[0] : serial input clock (SCLK). D1 to D3 must be connected together (SDA) When CSB is “H”, D[7:0] are high impedance. |
