The PIC24F “GB2” MCU family from Microchip has 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.
Hardware crypto engine supports AES, DES and 3DES standards, reduces software overhead, lowers power consumption and enables faster throughput. 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. GB2 consumes 180 µA/MHz Run currents and 18 nA Sleep currents.
PIC24F “GB2” devices available in 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).
