Microchip Technology PIC24FJ-GU4/GL4 16-Bit Microcontrollers

Microchip Technology PIC24FJ-GU4/GL4 16-Bit Microcontrollers (MCUs) offer up to 512KB of Dual Partition Flash supporting real-time Over-The-Air (OTA) updates and EEPROM Emulation. Along with several Core Independent Peripherals (CIPs), the PIC24FJ-GU4/GL4 MCUs include a full-speed USB and a segmented LCD controller with animation support. With high memory and sleep current down to a few hundred nA while retaining the complete RAM content, these devices are perfect for IoT, industrial, consumer, and medical applications.

The PIC24FJ-GU4/GL4 MCUs are supported in the MPLAB® Code Configurator (MCC) tool, reducing development time by allowing developers to configure the devices and libraries with just a few clicks. To address the evolving focus on safety and security, these MCUs offer hardware safety features and secure protection schemes, simplifying the design of smart, safe, secure, and connected applications. These MCUs feature protection schemes such as Flash OTP by ICSP™ Write Inhibit, which allows the entire Flash to be configured as One-Time-Programmable (OTP) memory, and CodeGuard™ Flash Security, which facilitates segmenting the memory and implementation access restrictions. These features, together with Microchip Technology's CryptoAuthentication™ ICs, ease the implementation of security into applications.

Offering an extended operating temperature of up to +125°C with AEC Q100 Grade 1 qualification, the PIC24FJ-GU4/GL4 MCUs are also well-suited for automotive and industrial applications. With a high level of analog integration, these devices simplify sensor interfacing and analog measurement while reducing the overall system BOM cost.
