SPECIFICHE TECNICHE

Funzione dei Pin di Interfaccia  

No. Simbolo Funzione
1 C2P Positive Terminal of the Flying Inverting CapacitorNegative Terminal of the Flying Boost CapacitorThe charge-pump capacitors are required between the terminals. They must be floated when the converter is not used.
2 C2N
3 C1P
4 C1N
5 VBAT Power Supply for DC/DC Converter Circuit
This is the power supply pin for the internal buffer of the DC/DC voltage converter. It must be connected to external source when the converter is used. It should be connected to VDD when the converter is not used.
6 VSS Ground of Logic Circuit
This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground.
7 VDD Power Supply for Logic
This is a voltage supply pin. It must be connected to external source.
8 CS# Chip Select
This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low.
9 RES# Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low, initialization of the chip is executed.
10 D/C# Data/Command Control
This pin is Data/Command control pin..
When the pin is pulled high and serial interface mode is selected, the data at SDIN is treated as data. When it is pulled low, the data at SDIN will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection.
11 SCLK When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK.
12 SDIN
13 IREF Current Reference for Brightness Adjustment
This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 12.5μA.
14 VCOMH Voltage Output High Level for COM Signal
This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected between this pin and VSS.
15 VCC Power Supply for OEL Panel
This is the most positive voltage supply pin of the chip. A stabilization capacitor should be connected between this pin and VSS when the converter is used. It must be connected to external source when the converter is not used.
