Description
The Atmel ATAES132 is a high-security Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM)
providing authentication, confidential, nonvolatile data storage capabilities. Access restrictions for the sixteen user zones
are independently configured, and any key can be used with any zone. Keys can also be used for standalone
authentication. This flexibility permits the ATAES132 to be used in a wide range of applications.
The AES-128 cryptographic engine operates in AES-CCM mode to provide authentication, stored data
encryption/decryption, and message authentication codes. Both internally stored data and/or small quantities of external
data can be protected by the ATAES132 device.
The ATAES132 pinout is compatible with standard Serial EEPROMs to allow placement on existing PC boards. The
Serial EEPROM portion of the ATAES132 instruction set is identical to the Atmel Serial EEPROM instruction set. The
ATAES132’s extended security functions are accessed by sending command packets to the ATAES132 using standard
Write instructions and reading responses using standard Read instructions. The ATAES132 Secure Serial EEPROM
architecture allows it to be inserted into existing applications.
The ATAES132 device incorporates multiple physical security mechanisms to prevent release of the internally stored
secrets. Secure personalization features are provided to facilitate third-party product manufacturing.

1.
Security
1.1
Advanced Encryption Standard (AES)
The ATAES132 cryptographic functions are implemented with a hardware cryptographic engine using the Advanced
Encryption Standard (AES) in the CCM (Counter mode Cipher block chaining Message authentication code) mode with
128-bit keys. AES-CCM mode provides both confidentiality and integrity checking with a single key. The integrity MAC
includes both the encrypted data and additional authenticate-only data bytes, as described in each command definition.
Each MAC is unique due to inclusion of a nonce and an incrementing MacCount register in the MAC calculation.
1.2
Hardware Security Features
The ATAES132 device contains physical security features to prevent an attacker from determining the internal secrets.
The ATAES132 includes tamper detectors for voltage, temperature, frequency, and light, as well as an active metal
shield over the circuitry, internal memory encryption, and various other features. The ATAES132 physical design and
cryptographic protocol are architected to prevent or significantly complicate most algorithmic, timing, and side-channel
attacks.
2.
Device Internal Regions
Seven distinct regions make up the internal organization of the ATAES132: User Memory, Information Region,
Configuration Memory, Counters, Key Memory, SmallZone, and the I/O Support regions.
Figure 2-1. Device Internal Regions

Information Region (36 bytes)
Configuration Memory (165 bytes)
Counters (2Kb)

Small Zone (32 bytes)
Free Space (96 bytes)
I/O Support SRAM
2.1
User Memory
The User Memory is comprised of 32Kb of nonvolatile memory, segmented into 16 zones. Access to the zones is
independently configurable to offer access restrictions, from open access, as in any standard Serial EEPROM, to full
restrictions that preclude Read/Write operations and will only permit internal, authenticated use for such data as security
keys.
2.2
Information Region
The Information Region holds read-only identification information, such as unique die serial numbers and other
information pertaining to the ATAES132.

2.3
Configuration Memory
The Configuration Memory offers the ability to customize access rights to different resources of the device as a means to
tailor the various security features of the device to one’s specific application. This customizing, formally known as
personalization, grants the application owner the ability to define custom access rights to device resources, from
counters and key usage to memory. After personalization, the application owner issues lock commands to render the
configuration permanent and to forever seal security keys and information in user zones configured to be confidential.
The Configuration Memory supports multi-step workflows to support the use of third-party services like programming
without compromising the content or application security. In addition, Atmel offers optional, value-add programming
services through the use of hardware security modules, which allow application owners to virtually inject their secrets into
the ATAES132.

1.
Changes to most of the configuration registers take effect immediately which allows the functionality to be
tested during the personalization process. Changes to the I2C Addr register take effect at the next Reset,
Power-Up, or Wake-Up from the Sleep state.
Counters
The Counters region contains 16 nonreversible monotonic counters. The Counter operation is customized during
personalization in the Configuration Memory to permit such features as free use, authenticated-only increments, and
control of key usage.
2.5
Key Memory
Key Memory holds sixteen 128-bit keys targeting various AES and AES-CCM operations. Key usage is customized
during personalization in the Configuration Memory to permit custom features like authentication-only, limited-use,
counter increment, user zone access, key permissions, and many other uses. The Key Memory is writeable only during
personalization and is never readable under any circumstances. One may only use an authentication procedure to
validate the content of a key; however, the ATAES132 offers a set of commands which, when so configured during
personalization, permits secure key creation, imports, and transfer of content from a confidential User Memory to key
space.
2.6
SmallZone
SmallZone is a 32-byte, general-purpose memory separate from the 32Kb user memory and with special features to aid
multi-step workflows. Configuration at personalization may make portions of this zone a mandatory input into
cryptographic calculations.
2.7
I/O Support
The I/O Support regions contains a FIFO and other registers, which together provide a means to send the ATAES132
commands and receive responses, including status information.
3.
Commands
The ATAES132 extends the command set of a standard Serial EEPROM to offer additional commands that solve various
security challenges. Unrestricted memory regions are accessible using standard Serial EEPROM I2C commands.
Restricted user memory regions, as well as security features, are still accessible by using standard I2C commands to

less than 250nA in the Sleep state to 10mA 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.
