If a memory read is attempted using an invalid address, then the EERR bit will be set to 1b and the RRDY bit should be set to
0b. Actual behavior in I
RRDY bit is 1b before the read, then it remains 1b. The ATAES132 operates correctly in SPI Interface mode.
This problem will be fixed in future revisions of ATAES132.
I
interface mode.
The random command does not support Mode Bit 2. This revision of the device can only generate random numbers for
external use using the random command. Nonce values can only be generated with the nonce command. If the host attempts
to use this mode with the ATAES132 first silicon, an error code will be generated.
The EncRead command does not support the key memory signature generation mode or the configuration memory signature
generation mode. Any attempt to read the configuration memory or key memory using the EncRead command generates an
error code
The absolute maximum operating voltage is 4.0V. The temperature sensor will be permanently damaged if the V
excess of 4.0V is applied to the device. Overvoltage damage to the temperature sensor will result in a permanent increase in
the power consumption of the device.
This problem will be fixed in future revisions of ATAES132.
If the rise time of V
device may not load the ChipConfig register correctly, causing the device to enter the wrong power state at power up. The
device may not load the I
device address; as a result it may be impossible for the host microcontroller to communicate with the ATAES132. Selection of
the wrong interface mode at power up could result in permanent damage to the ATAES132.
This problem will be fixed in future revisions of the ATAES132.
Pre-Production Errata (INFO DeviceNum = 0x0A04)
Pre-production version, not fully qualified.
SPI Mode 3 communication is not supported in this revision of the device. This problem will be fixed in future revisions of the
ATAES132.
The temperature sensor is non-functional and the TempSense command should not be executed. Execution of the
TempSense command will result in the part reseting.
