COG Module Specifications

Interface Pin Function

Pin No.	Symbol	Pin Type	Description
1	VSS	P	Ground pin.
2	VDD	P	Power supply for core logic operation. A capacitor should be connected between VDD and VSS under all circumstances.
3	NC		No connection
4	D/C#	I	This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data. When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
5	R/W#	I	This pin is read / write control input pin connecting to the MCU interface. When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW.
6	E	I	This pin is MCU interface input. When 6800 interface mode is selected, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH and the chip is selected.
7~14	DB0~ DB7	I/O	These pins are bi-directional data bus connecting to the MCU data bus. Unused pins are recommended to tie LOW.
15	NC		No connection
16	NC		No connection

FAQ

Q: What is a COG Module?

A: COG modules have the LCD driver mounted directly on an overlapping edge of one of the glass plates that make up the LCD. The resulting module is an integrated display, less than 3 mm thick, with all connections from the LCD driver to the LCD completely isolated from the environment.

Q: Can I get samples?

A: Yes, please give us sample orders.

Q: How can you guarantee the quality mass production?

A: Our products quality follow ISO9000 standard system, stable design team, more than years experience of technology team and strictly quality control system guarantee the quality of our products.

Q: When will you ship the items?

A: Samples ( in stock) will be take 5-7 days after receiving your payment, but it can be negotiated.

Q: Are COG Modules compatible with touchscreen functionality?

A: Yes, they can be integrated with touchscreen technology for interactive displays.
