Secure 2 click PID MIKROE-2760 Secure 2 click carries the ATAES132A, a cryptographic coprocessor with secure hardwarebased key storage from Microchip. The click is designed to run on either 3.3V or 5V power supply. Secure 2 click communicates with the target microcontroller over SPI and I2C interface, with additional functionality provided by the INT pin on the mikroBUS line. The click comes with stackable headers so you can put another click on the top of it. NOTE The click comes with stacking headers which allow you to combine it with other clicks more easily by using just one mikroBUS socket. ATAES132A features The ATAES132A is a high-security, Serial Electrically-Erasable and Programmable Read-Only Memory Serial EEPROM providing both authentication and confidential nonvolatile data storage capabilities. Access restrictions for the 16 user zones are independently configured, and any key can be used with any zone. In addition, keys can be used for standalone authentication. The AES-128 cryptographic engine operates in AES-CCM mode to provide authentication, stored data encryption/decryption, and Message Authentication Codes. Data encryption/decryption can be performed for internally stored data or for small external data packets, depending upon the configuration. Data encrypted by one ATAES132A device can be decrypted by another, and vice versa.
