Hardware Crypto Engine for Secure Data Industrial ■ Security door locks ■ Access control systems ■ Security cameras ■ POS terminals ■ Smart card readers ■ Heat/gas meters ■ IoT sensor nodes Computer ■ PC peripherals ■ Printers ■ Portable accessories Medical/Fitness ■ Pedometers ■ Wearable fi tness ■ Handheld devices 16-bit Embedded Control Solutions 7 Hardware Crypto Engine With the Internet of Things growing at a rapid rate, protecting embedded data and extending battery life are not an option, but a necessity. Devices in Microchip’s PIC24F “GB2” family are the first PIC® MCUs to offer an integrated hardware crypto engine along with eXtreme low power performance. This new family also features a True Random Number Generator (RNG) and One-Time- Programmable (OTP) key storage for protecting data in embedded 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 smart card applications. Key Features Cryptographic Engine ■ AES engine with 128, 192 or 256-bit key ■ DES/Triple DES (TDES) engine ■ Encryption, decryption and authentication ■ True Random Number Generator (RNG) ■ Achieve a higher level of data security with unique key ■ One-Time-Programmable (OTP) memory for secure key storage ■ Once written, keys cannot be read or overwritten by software ■ Core Independent Peripheral – offl oads CPU to save power and headroom eXtreme Low Power Features ■ 18 nA sleep, 180 μA/MHz Run ■ Enables integrity of data without sacrifi cing power consumption ■ VBAT allows the device to transition to a backup battery Connection to USB or Wireless Protocols ■ Integrated USB 2.0 device, host, OTG ■ Easy connection to certifi ed modules for Wi-Fi®, ZigBee®, Sub-GHz and Bluetooth® Low Energy Alternatively, you can add crypto functions in software to any PIC24 or dsPIC33 device using the free software found in the Microchip Libraries for Applications (MLA) download at www.microchip.com/MLA. Target Applications Application Note AN1861: Bluetooth Smart Communication Using Microchip’s RN4020 Module and 16-bit PIC Microcontroller Learn how low-power Bluetooth connectivity is an ideal match with the XLP PIC24 microcontrollers, especially those with integrated crypto engine for adding another layer of data protection for internet-connected applications. Bluetooth Low Energy or Bluetooth Smart has evolved to support applications that need simple command and control or quick status from a sensor. This lowpower protocol is ideal for connecting local embedded applications to the cloud through a smartphone or tablet. Development Tools The PIC24FJ128GB204 Plug-In Module (MA240037) plugs into the Explorer 16 Development Board (DM240001). To add low-power Bluetooth Smart connection, simply add the RN4020 Bluetooth Low Energy PICtail™/PICtail Plus Daughter Card (RN-4020-PICTAIL). This flexible development system makes it easy to customize for various other wired or wireless connectivity options including USB, Wi-Fi or ZigBee.
