PIC24F GB Family of Microcontrollers

USB, Low Power, Dual Partition Flash, Segment LCD and Scalable

With the Internet of Things (IoT) market continuing to grow by billions of devices each year, designers increasingly need lower-power microcontrollers (MCUs) that will enable these applications. PIC24F GB MCUs are low-power, high-performance devices that offer up to 1 MB of dual-partition Flash memory with live update capabilities. In addition to ultra-low-power performance, these MCUs feature Full-Speed USB host and device, high-speed Direct Memory Access (DMA), 12-bit Analog-to-Digital Converters (ADCs), cryptographic engine, built in op amps and much more.

Many embedded hardware systems, such as industrial and medical systems, handle extremely critical applications that cannot go offline for any reason. However, even the most well-designed systems will require bug fixes and the implementation of additional features. The ability to update the firmware on these systems without taking them offline is an essential requirement. Devices with dual-partition Flash with Live Update capability allow execution from one part of the memory while updating your code from the other, enabling you to update your firmware Over-The-Air (OTA) remotely or in the field without having to shut down your application. Select PIC24F ‘GB’ devices enable you to implement this capability in your application.

Target Applications

  • Internet of Things (IoT)
  • Medical fitness devices
  • Industrial automation
  • Battery powered devices
  • USB digital audio
  • White goods
  • HVAC control
  • Electricity metering
  • Security panels
  • Touch controllers
  • Fingerprint scanners
  • Embedded security

Key Features of the PIC24F GB Family

Key Feature Description
USB On-The-Go (OTG) compliant, dual-role capable; can act as either host or peripheral
Low Power Features eXtreme Low Power (XLP) technology with sleep currents as low as 30 nA, flexible wake-up sources and run currents down to 150 μA/MHz to create power-efficient applications
Segment LCD Integrated display controller with up to 512 segments and able to operate in sleep mode
Flexible Peripherals Wide range of basic and specialized peripherals including Crypto Engine, CLC, Real-Time Clock/Calendar (RTCC) and Pulse-Width Modulators (PWMs) designed to take the load off the CPU and reduce power consumption
Dual Partition Flash with Live Update Capable of storing two independent software applications, including bootloader, to enable programming of one partition while executing application code from the other and allow run-time switching between active partitions
Direct Memory Access (DMA) Dedicated DMA controller supporting both memory and peripheral data transfers to reduce CPU workload
Scalable Flash memory densities range from 16 KB to 1024 KB and RAM ranging from 4–32 KB with packages ranging from 28- to 121-pin options

Looking Beyond Low-Power MCUs

As more wearables, wireless sensor networks and other Internet of Things (IoT)-enabled smart devices are being powered by batteries, energy conservation is essential. Connected applications must minimize power consumption and, in extreme cases, last for up to 20 years while running from a single battery. Our devices with eXtreme Low Power (XLP) technology offer the industry’s lowest run and sleep currents for these applications.
