2. Description
The AT88SC0104CA member of the CryptoMemory® family is a high-performance secure memory providing 1 Kbit of user memory with advanced security and cryptographic features built in.
The user memory is divided into four 32-byte zones, each of which may be individually set with
different security access rights or effectively combined together to provide space for 1 to 4 data
files. The AT88SC0104CA features an enhanced command set that allows direct communication with microcontroller hardware 2-Wire interface thereby allowing for faster firmware
development with reduced code space requirements.
3. Smart Card Applications
The AT88SC0104CA provides high security, low cost, and ease of implementation without the
need for a microprocessor operating system. The embedded cryptographic engine provides for
dynamic, symmetric-mutual authentication between the device and host, as well as performing
stream encryption for all data and passwords exchanged between the device and host. Up to
four unique key sets may be used for these operations. The AT88SC0104CA offers the ability to
communicate with virtually any smart card reader using the asynchronous T = 0 protocol (Gemplus Patent) defined in ISO 7816-3.
4. Embedded Applications
Through dynamic, symmetric-mutual authentication, data encryption, and the use of cryptographic Message Authentication Codes (MAC), the AT88SC0104CA provides a secure place for
storage of sensitive information within a system. With its tamper detection circuits, this information remains safe even under attack. A 2-wire serial interface running at speeds up to 1.0 MHz
provides fast and efficient communications with up to 15 individually addressable devices. The
AT88SC0104CA is available in industry standard 8-lead packages with the same familiar pin
configuration as AT24CXXX serial EEPROM devices.

5. Pin Descriptions
5.1
Supply Voltage (VCC)
The VCC input is a 2.7V to 3.6V positive voltage supplied by the host.
5.2
Clock (SCL/CLK)
When using the asynchronous T = 0 protocol, the CLK (SCL) input provides the device with a
carrier frequency f. The nominal length of one bit emitted on I/O is defined as an “elementary
time unit” (ETU) and is equal to 372/f.
When using the synchronous protocol, data clocking is done on the positive edge of the clock
when writing to the device and on the negative edge of the clock when reading from the device.
5.3
Reset (RST)
The AT88SC0104CA provides an ISO 7816-3 compliant asynchronous Answer-To-Reset (ATR)
sequence. Upon activation of the reset sequence, the device outputs bytes contained in the 64bit Answer-To-Reset register. An internal pull-up on the RST input pad allows the device to operate in synchronous mode without bonding RST. The AT88SC0104CA does not support an
Answer-To-Reset sequence in the synchronous mode of operation.
5.4
Serial Data (SDA/IO)
The SDA/IO pin is bidirectional for serial data transfer. This pin is open-drain driven and may be
wired with any number of other open-drain or open-collector devices. An external pull-up resistor
should be connected between SDA/IO and VCC. The value of this resistor and the system capacitance loading the SDA/IO bus will determine the rise time of SDA/IO. This rise time will
determine the maximum frequency during read operations. Low value pull-up resistors will allow
higher frequency operations while drawing higher average power supply current. SDA/IO information applies to both asynchronous and synchronous protocols.

7. Device Operations for Synchronous Protocols
7.1
Clock and Data Transitions
The SDA pin is normally pulled high with an external device. Data on the SDA pin may change
only during SCL low time periods (see Figure 7-3 on page 6). Data changes during SCL high
periods will indicate a start or stop condition as defined below.
7.1.1
Start Condition
A high-to-low transition of SDA with SCL high defines a START condition which must precede all
commands (see Figure 7-4 on page 7).
7.1.2
Stop Condition
A low-to-high transition of SDA with SCL high defines a STOP condition. After a read sequence,
the STOP condition will place the EEPROM in a standby power mode (see Figure 7-4 on page
7).
7.1.3
ACKNOWLEDGE
All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words.
The EEPROM sends a zero to acknowledge that it has received each word. This happens during the ninth clock cycle (see Figure 7-5 on page 7).
5
5200AS–CRYPT–7/08
7.2
Memory Reset
After an interruption in communication due protocol errors, power loss or any reason, perform
"Acknowledge Polling" to properly recover from the condition. Acknowledge polling consists of
sending a start condition followed by a valid CryptoMemory command byte and determining if
the device responded with an ACKNOWLEDGE.

8. Device Architecture
8.1
User Zones
The EEPROM user memory is divided into 4 zones of 256 bits each. Multiple zones allow for
storage of different types of data or files in different zones. Access to user zones is permitted
only after meeting proper security requirements. These security requirements are user definable
in the configuration memory during device personalization. If the same security requirements are
selected for multiple zones, then these zones may effectively be accessed as one larger zone.

9. Control Logic
Access to the user zones occur only through the control logic built into the device. This logic is
configurable through access registers, key registers and keys programmed into the configuration
memory during device personalization. Also implemented in the control logic is a cryptographic
engine for performing the various higher-level security functions of the device.
10. Configuration Memory
The configuration memory consists of 2048 bits of EEPROM memory used for storage of passwords, keys, codes, and also used for definition of security access rights for the user zones.
Access rights to the configuration memory are defined in the control logic and are not alterable
by the user after completion of personalization.

10.1
Security Fuses
There are three fuses on the device that must be blown during the device personalization process. Each fuse locks certain portions of the configuration zone as OTP (One-Time
Programmable) memory. Fuses are designed for the module manufacturer, card manufacturer
and card issuer and should be blown in sequence, although all programming of the device and
blowing of the fuses may be performed at one final step.
11. Communication Security Modes
Communications between the device and host operate in three basic modes. Standard mode is
the default mode for the device after power-up. Authentication mode is activated by a successful
authentication sequence. Encryption mode is activated by a successful encryption activation following a successful authentication.

12. Security Options
12.1
Anti-Tearing
In the event of a power loss during a write cycle, the integrity of the device’s stored data is recoverable. This function is optional: the host may choose to activate the anti-tearing function,
depending on application requirements. When anti-tearing is active, write commands take longer
to execute, since more write cycles are required to complete them, and data is limited to a maximum of eight bytes for each write request.
Data is written first into a buffer zone in EEPROM instead of the intended destination address,
but with the same access conditions. The data is then written in the required location. If this second write cycle is interrupted due to a power loss, the device will automatically recover the data
from the system buffer zone at the next power-up. Non-volatile buffering of the data is done
automatically by the device.
During power-up in applications using Anti-Tearing, the host is required to perform ACK polling
in the event that the device needs to carry out the data recovery process.

AT88SC0104CA
5200AS–CRYPT–7/08
AT88SC0104CA
12.2
Write Lock
If a user zone is configured in the write lock mode, the lowest address byte of an 8-byte page
constitutes a write access byte for the bytes of that page. For example, the write lock byte at
$080 controls the bytes from $081 to $087.
Figure 12-1. Write Lock Example

$1
xxxx xxxx
locked
$2
xxxx xxxx
locked
$3
xxxx xxxx
$4
xxxx xxxx
$5
xxxx xxxx
locked
$6
xxxx xxxx
$7
xxxx xxxx
The Write-Lock byte itself may be locked by writing its least significant (rightmost) bit to “0”.
Moreover, when write lock mode is activated, the write lock byte can only be programmed – that
is, bits written to “0” cannot return to “1”.
In the write lock configuration, write operations are limited to writing only one byte at a time.
Attempts to write more than one byte will result in writing of just the first byte into the device.
12.3
Password Verification
Passwords may be used to protect READ and/or WRITE access of any user zone. When a valid
password is presented, it is memorized and active until power is turned off, unless a new password is presented or RST becomes active. There are eight password sets that may be used to
protect any user zone. Only one password is active at a time.
Presenting the correct WRITE password also grants READ access privileges.
12.4
Authentication Protocol
The access to a user zone may be protected by an authentication protocol. Any one of four keys
may be selected to use with a user zone.
Authentication success is memorized and active as long as the chip is powered, unless a new
authentication is initialized or RST becomes active. If the new authentication request is not validated, the card loses its previous authentication which must be presented again to gain access.
Only the latest request is memorized.

Note:
Authentication and password verification may be attempted at any time and in any order. Exceeding corresponding authentication or password attempts trial limit renders subsequent authentication or password verification attempts futile.
12.5
Cryptographic Message Authentication Codes
AT88SC0104CA implements a data validity check function in the standard, authentication or
encryption modes of operation.
In the standard mode, data validity check is done through a Modification Detection Code (MDC),
in which the host may read an MDC from the device in order to verify that the data sent was
received correctly.
In authentication and encryption modes, the data validity check becomes more powerful since it
provides a bidirectional data integrity check and data origin authentication capability in the form
of a Message Authentication Codes (MAC). Only the host/device that carried out a valid authentication is capable of computing a valid MAC. While operating in the authentication or encryption
modes, the use of MAC is required. For an ingoing command, if the device calculates a MAC different from the MAC transmitted by the host, not only is the command abandoned but the
security privilege is revoked. A new authentication and/or encryption activation will be required
to reactivate the MAC.

12.6
Encryption
The data exchanged between the device and the host during read, write and verify password
commands may be encrypted to ensure data confidentiality.
The issuer may choose to require encryption for a user zone by settings made in the configuration memory. Any one of four keys may be selected for use with a user zone. In this case,
activation of the encryption mode is required in order to read/write data in the zone and only
encrypted data will be transmitted. Even if not required, the host may still elect to activate
encryption provided the proper keys are known.
12.7
Supervisor Mode
Enabling this feature allows the holder of one specific password to gain full access to all eight
password sets, including the ability to change passwords.
12.8
Modify Forbidden
No write access is allowed in a user zone protected with this feature at any time. The user zone
must be written during device personalization prior to blowing the security fuses.
12.9
Program Only
For a user zones protected by this feature, data can only be programmed (bits change from a “1”
to a “0”), but not erased (bits change from a “0” to a “1”).
13. Protocol Selection
The AT88SC0104CA supports two different communication protocols.
Smartcard Applications:
Smartcard applications use ISO 7816-B protocol in asynchronous T = 0 mode for compatibility and interoperability with industry standard smartcard readers.
Embedded Applications:
A 2-wire serial interface provides fast and efficient connectivity with other logic devices or
microcontrollers.
The power-up sequence determines establishes the communication protocol for use within that
power cycle. Protocol selection is allowed only during power-up.
13.1
Synchronous 2-Wire Serial Interface
The synchronous mode is the default mode after power up. This is due to the presence of an
internal pull-up on RST. For embedded applications using CryptoMemory in standard plastic
packages, this is the only available communication protocol.
Power-up VCC, RST goes high also.
After stable VCC, SCL(CLK) and SDA(I/O) may be driven.
13
5200AS–CRYPT–7/08
Once synchronous mode has been selected, it is not possible to switch to asynchronous mode
without first powering off the device.

Five clock pulses must be sent before the first command is issued.
Asynchronous T = 0 Protocol
This power-up sequence complies to ISO 7816-3 for a cold reset in smart card applications.
VCC goes high; RST, I/O (SDA) and CLK (SCL) are low.
Set I/O (SDA) in receive mode.
Provide a clock signal to CLK (SCL).
RST goes high after 400 clock cycles.
The device will respond with a 64-bit ATR code, including historical bytes to indicate the memory
density within the CryptoMemory family.
Once asynchronous mode has been selected, it is not possible to switch to synchronous mode
without first powering off the device.

14. Initial Device Programming
Enabling the security features of CryptoMemory requires prior personalization. Personalization
entails setting up of desired access rights by zones, passwords and key values, programming
these values into the configuration memory with verification using simple WRITE and READ
commands, and then blowing fuses to lock this information in place.
Gaining access to the configuration memory requires successful presentation of a secure (or
transport) code. The initial signature of the secure (transport) code for the AT88SC0104CA
14
AT88SC0104CA
5200AS–CRYPT–7/08
AT88SC0104CA
device is $DD 42 97. This is the same as the WRITE 7 password. The user may elect to change
the signature of the secure code anytime after successful presentation.
After writing and verifying data in the configuration memory, the security fuses MUST be blown
to lock this information in the device. For additional information on personalizing CryptoMemory,
please see the application notes Programming CryptoMemory for Embedded Applications and
