Microcontroller with integrated hardware encryption
Microchip Technology’s PIC24F "GB2" microcontrollers (MCUs) are designed to enable secure data transfer and storage in portable embedded applications. They 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. 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.
