Appendix F. Key Memory Map
Table F-21. The key memory map.The ATAES132 key memory is located at address 0xF200.
The VolatileKey (KeyID = 0xFF) does not exist in EEPROM. It is a temporary key that resides in the internal SRAM memory.
The internal SRAM cannot be accessed directly. See section 4.3 for VolatileKey information.
Prior to locking the key memory, it can be written with either encrypted or cleartext data. Encrypted writes are performed using
the EncWrite command (see Section 7.11). Cleartext writes are performed using the standard SPI or I
Section 5.3). The key memory can never be read with the BlockRead command, or the EncRead command, or with standard
I
