CP2401-GQR

The CP2401-GQR from Silicon Labs is an integrated circuit designed for driving Liquid Crystal Displays (LCDs). It supports up to 128 segments and features a flexible interface compatible with both I2C and SMBus protocols, operating at speeds up to 400 kHz. This device is suitable for applications requiring precise timekeeping with its SmaRTClock functionality and offers expanded GPIO capabilities.

Key electrical characteristics include a supply voltage range of 1.8V to 3.6V and a low supply current of 620 µA. It also boasts ultra-low power modes, with LCD operation consuming less than 3 µA and shutdown current at a mere 0.05 µA. The component includes two general-purpose 16-bit timers and 256 bytes of RAM for general-purpose use.

Designed for surface mounting, the CP2401-GQR comes in a 48-TQFP package with dimensions of 7x7 mm. It operates across a wide temperature range of -40°C to +85°C, making it suitable for various environmental conditions. The device also features 5V tolerant I/O pins and an internal 20 MHz oscillator.

Example applications for this LCD driver include handheld equipment, utility meters, thermostat displays, and home security systems. Its combination of features, low power consumption, and interface flexibility makes it a versatile choice for embedded display solutions.
