- Industrial instrumentation panels
Display Drivers Procurement Notes
Verify the specific suffix GQR corresponds to the 48-pin TQFP package configuration. Confirm that the I2C interface requirements align with the host microcontroller's capabilities. Ensure the operating temperature range meets the environmental specifications of the final assembly. Check for any RoHS compliance documentation if required by regional regulations.
Display Drivers Selection Notes
Select this component when driving up to 128 segments is required with minimal power usage. The I2C interface simplifies wiring compared to parallel interfaces. Consider the TQFP-48 package size constraints during PCB layout. Verify that the bias requirements of the LCD panel are compatible with the internal driver capabilities.
Display Drivers Part Context
The CP2401-GQR belongs to the CP240x family of fixed-function LCD drivers. These devices also offer GPIO expansion and timekeeping functions. They are designed to increase available system RAM by offloading display management tasks from the main processor.
Display Drivers Replacement Considerations
The CP2401-GM is a QFN-48 variant within the same series. Other members like CP2400 or CP2402 may offer different segment counts or pinouts. Verify pin compatibility before substituting.
