CP2400-GM

Display Drivers Overview

The CP2400-GM is a fixed-function LCD driver from the Silicon Labs CP240x family, housed in a QFN-48 package. It supports up to 128 LCD segments and includes 256 bytes of general-purpose RAM for system expansion. The device operates at a maximum clock frequency of 25 MHz with a supply voltage range of 3.3 V (min/max) and a maximum power consumption of 790 uA. It features an SPI interface and functions within a temperature range of -40°C to +85°C.

Display Drivers Feature Summary

• Drives up to 128 LCD segments via SPI interface
• Includes 256 bytes of expandable system RAM
• Digital pins tolerate 5 V voltage levels

Display Drivers Applications

• Battery-powered IoT devices requiring low power LCD control
• Systems needing GPIO expansion and timer functionality
• Embedded applications utilizing C8051F9xx microcontrollers

Display Drivers Procurement Notes

Verify component status as the CP2400-GM is listed as End-of-Life or Not Recommended for New Designs by major distributors. Confirm availability through authorized channels or secondary markets. Ensure compatibility with existing PCB footprints if replacing obsolete inventory. Check RoHS compliance details before final procurement decisions.

Display Drivers Selection Notes

Select this component when a fixed-function LCD controller with SPI interface is required for systems supporting up to 128 segments. It is suitable for designs needing integrated RAM expansion and 5 V tolerant digital I/O. Consider the QFN-48 package constraints and operating temperature range of -40°C to +85°C during board layout and thermal management planning.

Display Drivers Part Context

Part of the CP240x family of ultra-low power LCD controllers designed to reduce system size and power consumption. These devices connect easily to any microcontroller via SPI or I2C interfaces. The family allows designers to choose the optimal MCU while offloading LCD driving tasks, providing additional GPIOs and timers to enhance system capabilities.

Display Drivers Replacement Considerations

CP2400-GQ is a pin-compatible alternative within the same series but utilizes a TQFP48 package instead of QFN48.
