It must be connected to external source. 2 VSS G 3 SW I Ground for System This is a ground pin. It must be connected to external source. Terminal of Switch Normally Open 4 SW I Terminal of Switch Normally Open 5 6 BS1 BS2 I Communication Protocol Select These pins are MCU interface selection input. See the following table: BS1 BS2 68XX-parallel 0 1 80XX-paraelle 1 1 Serial 0 0 7 CS# I 8 RES# I 9 D/C# I 10 W/R# (R/W#) I 11 RD#(E) I 12 NC - Reserved Pin D0~D7 I 21 VSS G 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, D1 will be the serial data input SDIN and the D0 will be the serial clock input SCLK. Ground for System This is a ground pin. It must be connected to external source. 22 VCC-C TL I 23 NC - 24 VCC P 13~20 [email protected] Chip Select This is the chip select input. The chip is enable for MCU communication only when CS# is pulled low. Power Reset for Controller and Drive This is reset signal input. When the pin is low , initialization of the chip is executed. Data/ Command Control This pin is Data/Command control pin. When the pin is pulled high, the input at D0~D7 is treated as display data. When the pin is pulled low, the input at D0~D7 will be transferred to the command register. Write or Read/Write Select When 80xx interface mode is selected, the pin will be the Write (WR#) input. When interfacing to a 68xx-series microprocessor, the 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. Read or Read/Write Enable When 80xx interface mode is selected, the pin will be the Read (RD#) input. When interfacing to a 68xx-series microprocessor, the 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. OLED Driver Power Supply ON/ OFF Control When this pin is pulled high, the panel power supply will be turned ON. When this pin is pulled low, the panel power supply will be turned OFF. Reserved Pin Voltage Output High Level for COM Signal This pin is OLED driver power supply. When VCC-CTL is pulled high, the pin will be output about 14V voltage (Built in Panel Power Supply). www.greatecs.com 2 OLED Push Switches 96RGBx64 (0.95”) OLED Switches Snap-In Type YOD2B ABSOLUTE MAXIMUM RATINGS Parameter Symbol Min Max Unit Notes Supply Voltage VDD -0.3 4 V 1,2 Driver Supply Voltage Vcc 0 15 V 1,2 Vcc Supply Current Icc - 25 mA 1,2 Operating Temperature TOP -30 70 ɗ - Storage Temperature TSTG -40 80 ɗ - Note1烉All the above voltages are on the basis of “GND=0V” Note2烉When this module is used beyond the above absolute maximum ratings, permanent breakage of the module may occur.
