CP2403-GMR

Display Drivers Overview

The CP2403-GMR is a liquid crystal display driver manufactured by Silicon Labs, belonging to the CP240x device family. It supports up to 64 segments and 8 commons for driving LCD panels. The component operates on a single supply voltage ranging from 1.8V to 3.6V and features an I2C/SMBus interface for communication. Key electrical parameters include a maximum clock frequency of 25 MHz and a typical operating current of 790 µA. It is housed in a 32-lead QFN package with a temperature range spanning from -40°C to +85°C.

Display Drivers Feature Summary

• Supports flexible segment and common configurations for various LCD panel sizes
• Integrates an I2C/SMBus compatible serial interface for simplified system connectivity
• Designed for low power consumption suitable for battery-operated applications

Display Drivers Applications

• Smart home control panels
• Industrial instrumentation displays
• Medical device user interfaces

Display Drivers Procurement Notes

Verify the specific suffix 'GMR' indicates the reel packaging variant when ordering. Confirm the I2C address configuration matches your system design requirements. Ensure the PCB footprint aligns with the 32-lead QFN package dimensions provided in the official datasheet. Check for RoHS compliance status if required by your manufacturing standards.

Display Drivers Selection Notes

Select this model if your application requires an I2C interface rather than SPI. Compare segment counts against other CP240x variants like the CP2400 or CP2401 to ensure sufficient drive capability. Consider the thermal performance within the specified operating temperature range. Evaluate the power supply constraints to ensure compatibility with the 1.8V to 3.6V operating range.

Display Drivers Part Context

This part belongs to the CP240x LCD Driver Family from Silicon Labs. The family includes variants with different segment capacities and interface options such as SPI and I2C. These drivers are designed to replace traditional discrete logic solutions for LCD control, offering integrated multiplexing and bias generation capabilities in a compact form factor.

Display Drivers Replacement Considerations

Check for direct pin-compatible alternatives within the CP240x family that may offer different interface types or segment counts. Verify if older revisions of the CP2403 series are still available if legacy support is needed.
