4. Power Management Features
The ATAES132 supports four power states that offer great flexibility in reducing its power consumption, especially in
low-power embedded systems. These are the Active, Standby, Sleep, and Off sates. Power consumption ranges from
less than 250nA in the Sleep state to10mA in the Active state. The ATAES132 can power-up into any of the powered
states, if so configured. It can also enter the standby or sleep states after receipt of a Sleep command from the Host.
0x02 Random Returns a 128-bit random number from the internal random number generator.
0x00 Reset Resets the device, clearing the cryptographic status.
0x11 Sleep Places the device in the sleep state or standby state to reduce power consumption.

5. Electrical Characteristics
5.1 Absolute Maximum Ratings*
5.2 Reliability
The ATAES132 is fabricated with Atmel high reliability CMOS EEPROM manufacturing technology. The reliability ratings
in Table 5-1 apply to each byte of the EEPROM memory.

*Notice: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent
damage to the device. This is a stress rating only,
and functional operation of the device at these or
any other condition beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.

5.3 DC Characteristics
5.3.1 Supply Voltage and Current Characteristics
Notes: 1. Typical values are at 25C, and are for reference only. Typical values are not tested or guaranteed
2. On power-up, V
CC
must rise continuously from V
SS
to the operating voltage, with a rise time no faster than
1V/μs.
3. All input pins must be held at either V
SS
or V
CC
during this measurement
4. Measurement is performed at the maximum serial clock frequency
5. The ATAES132 does not support hot swapping or hot plugging. Connecting or disconnecting this device to a
system while power is energized can cause permanent damage to ATAES132
