Pin No. Symbol Level Description
1 GND P Ground Pin
2 V16 I This is the most positive voltage supply pin of the chip. It can be supplied externally or generated internally by using internal DC-DC voltage converter.
3 VCI P DCDC buffer Power Supply
4 GND P Ground Pin
5 VCC P Power Pin
6 BVR I Brightness control pin. It should be connected to VCC.
7 DVR I Pre charge time control. It should be connected to VCC.
8 VBREF O This pin is the internal voltage reference of DCDC1 circuit. A stabilization capacitor should be connected between this pin and GND
9 RESE I NMOS source input pin:
This pin connects to the source current pin of the external NMOS of the booster circuit.
10 GDR O Gate drive pulse output pin:
This output pin drives the gate of external NMOS of the booster circuit.
11 FB I Feedback voltage input pin:
This pin is the feedback resistor input of the booster circuit. It is used to adjust the booster output voltage level.

15 RESETB I Reset pin
16 RS I Register Select Input Pin
When this pin is set to "0", it is used as an Instruction Register.
When this pin is set to "1", it is used for as the Data Register.
17 CSB I Chip select input pins
Data / instruction I/O is enabled only when CSB is “L”.
18 RDB I Read / Write execution control pin
MPU Type RDB Description
6800-series E Read / Write control input pin
- RW = “H”: When E is “H”, DB0 to DB7 are in an output status.
- RW = “L”: The data on DB0 to DB7 are latched at the falling edge the E signal.
8080-series RDB Read enable clock input pin
When / RDB is “L”, DB0 to DB7 are in an output status.
19 WRB I Read / Write execution control pin
MPU Type WRB Description
6800-series RW Read / Write control input pin
- RW = “H” : read
- RW = “L” : write
8080-series WRB Write enable clock input pin.
The data on DB0 to DB7 are latched at the rising edge of the /WRB signal.
20 SDA I/O SDA is the serial data input for I2C.
21 SDC I/O SDC is the serial clock input/output for I2C.
22~25 DB7~DB4 I/O High Order Bidirectional Data I/O Pins
These pins are used for data transfer and reception between the MPU and WS0012.
When SPI is selected, DB5 will be the serial clock input: SCL
DB7 will be the serial data input: SDI.
DB6 will be the serial data output: SDO.
26~29 DB3~DB0 I/O Low Order Bidirectional Data I/O Pins
These pins are used for data transfer and reception between the MPU and WS0012.
These pins are not used during a 4-bit operation.
30 GND P Ground Pin
