The Atmel ATAES132A is a high-security, Serial Electrically-Erasable and Programmable Read-Only Memory
(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. This flexibility permits the ATAES132A to be used in a
wide range of applications.
It can be used as regular EEPROM also, but i am not sure what will be the device address.
The regular logic(8 address bits) 0x1-0-1-0-A2-A1-A0-R/W, didnt work. How to determine the address of the AES132A
1. What will be the device address if AES132A used as regular EEPROM?
2. And i wish to encrypt the external 16byte(from RAM) data to get converted into ciphertext with AES132 ccm engine, and store back in my ATMEGA Internal EEPROM.
The steps would be to send command and receive command on its buffer and continuously monitoring status register.
But then again the basic interface to send command is through I2C bus. And I am not sure what should be the device address?
can anyone help, who has worked with AES132A?
