The PIC24F “GB2” devices offer up to 128 KB Flash and 8 KB RAM in small 28- or 44-pin packages for battery-powered or portable applications such as sensor nodes for the Internet of Things, access control systems, and door locks.
The PIC24F “GB2” family integrates several security features to protect embedded data. The full hardware cryptographic engine supports AES, DES, and 3DES standards, reduces software overhead, lowers power consumption, and increases operating speed. This is another example of Microchip's Core Independent Peripherals (CIPs), which can operate without CPU supervision. A random number generator (RNG) creates random keys for data encryption, decryption, and authentication to provide a higher level of security. For added protection, one-time programmable key storage prevents the encryption key from being read or overwritten. These security features enhance the integrity of embedded data without sacrificing power efficiency. Using XLP technology, the “GB2” family achieves operating currents of 180 µA/MHz and sleep currents of 18 nA for very long battery life in portable applications.
In terms of connectivity, the “GB2” family integrates USB for device or host connections, as well as a UART with ISO7816 support, which is practical for smart card applications. Thanks to these features, PIC24F “GB2” devices protect embedded data, consume less power, and maximize battery life, all in packages as small as the 28-pin QFN for medical and fitness applications such as pedometers, wearable devices, and portable devices; computer applications such as PC peripherals, printers, and portable accessories; and industrial applications such as security door locks, access control systems, security cameras, POS systems, smart card readers, heat/gas meters, and sensor nodes for the Internet of Things. Microchip also offers a flexible range of certified wireless modules for Wi-Fi®, ZigBee®, Bluetooth®, and Bluetooth Low Energy, making it easy to add wireless connectivity to a PIC24 “GB2” application.
The combination of the PIC24F “GB2” family and Microchip’s embedded wireless solutions enables low-power wireless connectivity to Internet-connected objects, as well as faster operation and lower bill of materials costs.
The PIC24F “GB2” family is supported by Microchip’s standard suite of premium development tools, including the Explorer 16 Development Board (DM240002) priced at $129.99; the PIC24FJ128GB204 USB Plug-in Module (MA240037) at
