PIC24F ‘GU/GL’ Family of Microcontrollers

Low Power | Segment LCD | USB | Secure IoT | Safety | Sensor Interfacing

The PIC24F ‘GU/GL’ family of eXtreme Low Power (XLP) microcontrollers (MCUs) enables the development of an array of innovative applications, both with and without displays. Packed with more than 14 types of Core Independent Peripherals (CIPs) that can function in power-saving modes, the PIC24F ‘GU/GL’ MCUs offer ultra-low power operation for battery-powered and other power-conscious designs. They also feature an integrated segment LCD display driver that offers display segments ranging from 42 to 480 pixels to support a variety of display sizes.  

Securing your connected or stand-alone system is critical to protect it from attacks. The PIC24F ‘GU/GL’ MCUs include code protection features and work with our CryptoAuthentication™ devices to simplify adding security to your application. The CryptoAuthLib™ Library, which is supported by MPLAB® Code Configurator (MCC), eliminates the complexities of developing secure designs. MCC is a free and easy-to-use graphical programming environment that also simplifies your overall code development and speeds up your time to market.

Featured Core Independent Peripheral: LCD with Autonomous Animation

Most display applications involve a few common animations like blinking, periodically alternating between displays and blanking of pixels. By using the integrated LCD driver with autonomous animation, you can offload most of these animation routines from the CPU. This allows you to enable animation in power-saving modes while the CPU is in doze, idle or sleep mode.

Quickly Design a Display Interface with MPLAB Code Configurator (MCC)

Reduce your display design time to minutes with the help of MCC. It eliminates the meticulous and time-consuming task of mapping the pins and segments and allows you to import display icons to easily customize your display design.
