Description
®
®
The Atmel 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
one to four 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 1.0MHz 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.

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 4-3 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 4-4 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 4-4 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 (see Figure 4-5 on page 7).
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 nine 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 four 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.

8.
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.

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.

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 8mS 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 2mS, 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.

AT88SC0404C [SUMMARY DATASHEET]
Atmel-2023MS-CryptoMem-AT88SC0404C-Datasheet-Summary_122013
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).
