Description
The AT88SC0404C member of the CryptoMemory® family is a high-performance secure memory providing 4 Kbits of
user memory with advanced security and cryptographic features built in. The user memory is divided into four 128-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.
1.1.
Smart Card Applications
The AT88SC0404C provides high security, low cost, and ease of implementation without the need for a microprocessor
operating system. The embedded cryptographic engine provides for dynamic and 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 AT88SC0404C offers the ability
to communicate with virtually any smart card reader using the asynchronous T = 0 protocol (Gemplus Patent) defined
in ISO 7816-3.
1.2.
Embedded Applications
Through dynamic and symmetric mutual authentication, data encryption, and the use of encrypted checksums, the
AT88SC0404C 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 1.0 MHz is used for fast
and efficient communications with up to 15 devices that may be individually addressed. The AT88SC0404C is available
in industry standard 8-lead packages with the same familiar pinout as 2-wire serial EEPROMs.

Pin Descriptions
2.1.
Supply Voltage (VCC)
Random
Generator
EEPROM
The VCC input is a 2.7V to 5.5V positive voltage supplied by the host.
2.2.
Clock (SCL/CLK)
In the asynchronous T = 0 protocol, the SCL/CLK input is used to provide 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 the
synchronous protocol is used, the SCL/CLK input is used to positive edge clock data into the device and negative edge
clock data out of the device.
2.3.
Reset (RST)
The AT88SC0404C provides an ISO 7816-3 compliant asynchronous answer to reset sequence. When the reset
sequence is activated, the device will output the data programmed into the 64-bit answer-to-reset register. An internal
pull-up on the RST input pad allows the device to be used in synchronous mode without bonding RST. The
AT88SC0404C does not support the synchronous answer-to-reset sequence.
2.4.
Serial Data (SDA/IO)
The SDA 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 and VCC.
The value of this resistor and the system capacitance loading the SDA bus will determine the rise time of SDA. 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. SDA/IO information applies to both asynchronous and
synchronous protocols.
When the synchronous protocol is used, the SCL/CLK input is used to positive edge clock data into the device and
negative edge clock data out of the device.

Device Operation for Synchronous Protocols
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 5 on page 7). Data changes
during SCL high periods will indicate a start or stop condition as defined below.
START CONDITION:
A high-to-low transition of SDA with SCL high is a start condition which must precede any
other command (see Figure 6 on page 7).
STOP CONDITION:
A low-to-high transition of SDA with SCL high is a stop condition. After a read sequence, the
stop command will place the EEPROM in a standby power mode (see Figure 6 on page 7).
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.
MEMORY RESET:
After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by
following these steps:
1.
2.
3.
Clock up to 9 cycles.
Look for SDA high in each cycle while SCL is high.
Create a start condition.

Device Architecture
5.1.
User Zones
The EEPROM user memory is divided into 4 zones of 1024 bits each. Multiple zones allow for different types of data or
files to be stored in different zones. Access to the user zones is allowed only after security requirements have been
met. These security requirements are defined by the user during the personalization of the device in the configuration
memory. If the same security requirements are selected for multiple zones, then these zones may effectively be
accessed as one larger zone.

Control Logic
Access to the user zones occurs 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.

Configuration Memory
The configuration memory consists of 2048 bits of EEPROM memory used for storing passwords, keys and codes and
for defining security levels to be used for each user zone. Access rights to the configuration memory are defined in the
control logic and may not be altered by the user.

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 memory as OTP 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.
9.
Protocol selection
The AT88SC0404C supports two different communication protocols.
•
•
Smart Card Applications: The asynchronous T = 0 protocol defined by ISO 7816-3 is used for compatibility with
the industry’s standard smart card readers.
Embedded Applications: A 2-wire serial interface is used for fast and efficient communication with logic or
controllers.
The power-up sequence determines which of the two communication protocols will be used.
9.1.
Asynchronous T = 0 Protocol
This power-up sequence complies with 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 the asynchronous mode has been selected, it is not possible to switch to the synchronous
mode without powering off the device.

Synchronous 2-wire Serial Interface
The synchronous mode is the default after powering up VCC due to an internal pull-up on RST. For embedded
applications using CryptoMemory in standard plastic packages, this is the only communication protocol.
•
•
Power-up VCC, RST goes high also.
After stable VCC, CLK-SCL and I/O-SDA may be driven.

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.

11.
Security Options
11.1.
Anti-tearing
In the event of a power loss during a write cycle, the integrity of the device’s stored data may be recovered. 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 are limited to eight bytes.
Data are written first to a buffer zone in EEPROM instead of the intended destination address, but with the same
access conditions. The data are 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.
In 2-wire mode, the host is required to perform ACK polling for up to 8 ms after write commands when anti-tearing is
active. At power-up, the host is required to perform ACK polling, in some cases for up to 2 ms, in the event that the
device needs to carry out the data recovery process.
11.2.
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.
Example:
The write lock byte at $080 controls the bytes from $080 to $087.

locked
The write lock byte may also 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, only one byte can be written at a time. Even if several bytes are received, only the first
byte will be taken into account by the device.
12
AT88SC0404C
2023KS–SMEM–10/09
AT88SC0404C
12.
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, but write
passwords give read access also.
12.1.
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.
The 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 and it should be presented again. Only the last request is memorized.
Note:
Password and authentication may be presented at any time and in any order. If the trials limit has been
reached (after four consecutive incorrect attempts), the password verification or authentication process will not
be taken into account.

12.2.
Checksum
The AT88SC0404C implements a data validity check function in the form of a checksum, which may function in
standard, authentication or encryption modes.
In the standard mode, the checksum is implemented as 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 the authentication and encryption modes, the checksum becomes more powerful since it provides a bidirectional
data integrity check and data origin authentication capability in the form of a Message Authentication Code (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 a 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 mode is also reset. A
new authentication and/or encryption activation will be required to reactivate the MAC.
12.3.
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 elect to
activate encryption provided the proper keys are known.
12.4.
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.
12.5.
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.
12.6.
Program Only
For a user zone protected by this feature, data within the zone may be changed from a “1” to a “0”, but never from a “0”
to a “1”.
13.
Initial Device Programming
To enable the security features of CryptoMemory, the device must first be personalized to set up several registers and
load in the appropriate passwords and keys. This is accomplished through programming the configuration memory of
CryptoMemory using simple write and read commands. To gain access to the configuration memory, the secure code
must first be successfully presented. For the AT88SC0404C device, the secure code is $60 57 34. 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 Initializing CryptoMemory for Smart Card Applications (at www.Atmel.com).
