Engineering Change Notification - NHD-C128128BZ-FSW-GBW: 9/1/26
This notice is to inform you of a change to the following COG LCD:
- NHD-C128128BZ-FSW-GBW
The ST7528 controller IC used in this display has been discontinued by the IC manufacturer. The controller IC in the new revision of the LCD has been upgraded to ST75160i. The new IC’s instruction set and initialization sequence are different than the previous IC. Details of the changes are described in the Product Transition Guide.
The new LCD version adds support for I2C interface which can be selected by using the interface select signals. There is a small change to the mechanical dimensions of the FPC, which is detailed in the Product Transition Guide.
The new version of the display does not require external capacitors to be added by the user. These capacitors have been added on the FPC cable as a design improvement. The pins that previously required a capacitor have been changed to no-connects. Details of the pinout change are described in the Product Transition Guide.
The new displays will be labeled with a different revision control number after the part number. See example below.
