Description
The AT88SC12816C member of the CryptoMemory® family is a high-performance
secure memory providing 128 Kbits of user memory with advanced security and crypto-
graphic features built in. The user memory is divided into 16 1-Kbyte zones, each of
which may be individually set with different security access rights or combined together
to provide space for one to four data files.
Smart Card Applications The AT88SC12816C provides high security, low cost, and ease of implementation with-
out 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 opera-
tions. The AT88SC12816C offers the ability to communicate with virtually any smart
card reader using the asynchronous T = 0 protocol (Gemplus Patent) defined in ISO
7816-3. Communication speeds up to 153,600 baud are supported by utilizing ISO
7816-3 Protocol and Parameter Selection.
Embedded Applications
Through dynamic, symmetric-mutual authentication, data encryption, and the use of
encrypted checksums, the AT88SC12816C provides a secure place for storage of sen-
sitive information within a system. With its tamper detection circuits, this information
remains safe even under attack. A 2-wire serial interface running at 1.5 MHz is used for
fast and efficient communications with up to 15 devices that may be individually
addressed. The AT88SC12816C is available in industry standard 8-lead packages with
the same familiar pinout as 2-wire serial EEPROMs.

Pin Descriptions
Supply Voltage (VCC)
Clock (SCL/CLK)
The VCC input is a 2.7V to 5.5V positive voltage supplied by the host.
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 nega-
tive edge clock data out of the device.

AT88SC12816C
Reset (RST)
The AT88SC12816C provides an ISO 7816-3 compliant asynchronous answer to reset
sequence. When the reset sequence is activated, the device will output the data pro-
grammed 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
AT88SC12816C does not support the synchronous answer-to-reset sequence.
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 exter-
nal 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 aver-
age power supply current. 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 CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an exter-
nal device. Data on the SDA pin may change only during SCL low time periods (see
Figure 4 on page 6). Data changes during SCL high periods will indicate a start or stop
condition as defined below.
Synchronous
Protocols
START CONDITION: A high-to-low transition of SDA with SCL high is a start condition
which must precede any other command (see Figure 5 on page 6).
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 5 on page 6).
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. Clock up to 9 cycles.
2. Look for SDA high in each cycle while SCL is high.
3. Create a start condition.

Device Architecture
User Zones
The EEPROM user memory is divided into 16 zones of 8,192 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 con-
figuration zone. 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 zone during device personalization. Also implemented in the control
logic is a cryptographic engine for performing the various higher-level security functions
of the device.
7
5016FS–SMEM–7/06
Configuration Zone
The configuration zone consists of 2048 bits of EEPROM memory used for storing pass-
words, keys and codes and defining security levels to be used for each user zone.
Access rights to the configuration zone 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 personaliza-
tion process. Each fuse locks certain portions of the configuration zone 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.
Protocol Selection
The AT88SC12816C 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.
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.

After a successful ATR, the Protocol and Parameter Selection (PPS) protocol, as
defined by ISO 7816-3, may be used to negotiate the communications speed with Cryp-
toMemory devices 32 Kbits and larger. CryptoMemory supports D values of 1, 2, 4, 8,
12, and 16 for an F value of 372. Also supported are D values of 8 and 16 for F = 512.
This allows selection of 8 communications speeds ranging from 9600 baud to 153,600
baud.
Synchronous
2-wire Serial Interface
The synchronous mode is the default after powering up VCC due to the 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 acti-
vated by a successful authentication sequence. Encryption mode is activated by a
successful encryption activation following a successful authentication.

Security Options
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 com-
plete 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.
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.
$080
$081
$082
$083
$084
$085
$086
$087
@
xxxx xxxx
locked
xxxx xxxx
locked
xxxx xxxx
locked
11011001
xxxx xxxx
xxxx xxxx
xxxx xxxx
xxxx xxxx
$80
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 pro-
grammed – 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.

5016FS–SMEM–7/06
AT88SC12816C
Password Verification
Authentication Protocol
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.
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 authentica-
tion 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 verifica-
tion or authentication process will not be taken into account.

Write DATA
Checksum
The AT88SC12816C implements a data validity check function in the form of a check-
sum, 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 a 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 capa-
bility 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 ongoing
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 authentica-
tion and/or encryption activation will be required to reactivate the MAC.
11
5016FS–SMEM–7/06
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 zone. 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.
Supervisor Mode
Modify Forbidden
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.
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.
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”.
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 zone of CryptoMemory using sim-
ple write and read commands. To gain access to the configuration zone, the secure
code must first be successfully presented. For the AT88SC12816C device, the secure
code is $22 EF 67. After writing and verifying data in the configuration zone, 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 CryptoM-
emory for Embedded Applications and Initializing CryptoMemory for Smart Card
Applications (at www.Atmel.com).
