Microchip announces PIC24F GB2 microcontroller with encryption

June 30, 2014 - Microchip Technology announced PIC24F PIC microcontrollers (MCUs) with an integrated hardware crypto engine, a Random Number Generator (RNG) and One-Time-Programmable (OTP) key storage for protecting data in embedded applications. The PIC24F "GB2" devices offer up to 128 KB Flash and 8 KB RAM in small 28- or 44-pin packages, for battery-operated or portable applications such as "Internet of Things" (IoT) sensor nodes, access control systems and door locks.

Several security features are integrated into the PIC24F "GB2" family, to protect embedded data. The fully featured hardware crypto engine, supporting the AES, DES and 3DES standards, reduces software overhead, lowers power consumption and enables faster throughput. This is another example of Microchip's Core Independent Peripherals, which can run with no CPU supervision. Also, a Random Number Generator creates random keys for data encryption, decryption and authentication, to provide a higher level of security. For additional protection, the One-Time-Programmable (OTP) key storage prevents the encryption key from being read or overwritten. These security features increase the integrity of embedded data without sacrificing power consumption. With XLP technology, the "GB2" family achieves 180 µA/MHz Run currents and 18 nA Sleep currents, for very long battery life in portable applications.

For connectivity, the "GB2" family integrates USB for device or host connections, as well as a UART with ISO7816 support, which is helpful for smartcard applications. With these features, the PIC24F "GB2" devices protect embedded data while conserving power and maximising battery life, all in packages as small as 28-pin QFN for medical/fitness applications (e.g., pedometers, wearable fitness, handheld devices), computer applications (e.g., PC peripherals, printers, portable accessories) and industrial applications (e.g., security door locks, access control systems, security cameras, POS terminals, smart card readers, heat/gas meters, IOT sensor nodes). Microchip also has a flexible range of certified wireless modules for Wi-Fi, ZigBee, Bluetooth and Bluetooth Low Energy, making it easy to add wireless connections to a PIC24 "GB2" application.
 
Development support
The PIC24F "GB2" family is supported by Microchip's standard suite of development tools, including the Explorer 16 Development Board (part # DM240002), PIC24FJ128GB204 Plug In Module for USB (part # MA240037), PIC24FJ128GA204 Plug In Module for non-USB (part # MA240036) and USB PICtail Plus Daughter Board  (part # AC164131). In addition, wireless connections can be added using one of Microchip's Wireless PICtail Daughter Boards, including the WiFi PICtail Development Board (part # RN-171-PICtail), and Bluetooth LE PICtail/PICtail Plus (part # RN-4020-PICtail).
