CP2401-GQ

Display Drivers Overview

The CP2401-GQ is a fixed-function LCD driver from the Silicon Labs CP240x family, housed in a TQFP-48 package. It supports up to 128 LCD segments and includes 256 bytes of general-purpose RAM for system expansion. The device operates on a single 3.3 V supply with a maximum clock frequency of 25 MHz. It features an SMBus/I2C interface for communication with host microcontrollers. Operating temperatures range from -40°C to +85°C, with a maximum power consumption of 790 µA.

Display Drivers Feature Summary

• Supports driving up to 128 LCD segments via a dedicated controller interface.
• Integrates 256 bytes of general-purpose RAM to extend available system memory.
• Enables low-power operation with ultra-low standby current modes.
• Provides digital I/O pin voltage tolerance compatible with 5 V systems.

Display Drivers Applications

• Development and testing of LCD driver applications using CP2401 firmware libraries
• Integration with C8051F9xx microcontrollers via SMBus interface
• Systems requiring extended GPIO capabilities through the LCD controller

Display Drivers Procurement Notes

Verify component status as the CP2401-GQ is listed as End-of-Life (EOL). Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and design-in requirements before procurement. Check for RoHS compliance documentation specific to the manufacturing batch.

Display Drivers Selection Notes

Select this component when a fixed-function LCD driver with SMBus connectivity is required. It is suitable for designs needing up to 128 segments and additional RAM expansion. Consider the TQFP-48 package constraints and 3.3 V operating voltage. Evaluate alternatives if active production status is mandatory for long-term supply.

Display Drivers Part Context

Part of the CP240x LCD controller family, which offers low-power solutions for segment-based displays. The series includes variants with SPI or SMBus interfaces and different segment capacities. These devices are designed to reduce system size and power consumption by offloading LCD control tasks from the main MCU.
