Description

The AT88SC6416C member of the CryptoMemory family is a high-performance secure

memory providing 64 Kbits of user memory with advanced security and cryptographic

features built in. The user memory is divided into 16 512-byte 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.

The AT88SC6416C 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 AT88SC6416C offers the ability to communicate with virtually any smart card

reader using the asynchronous T = 0 protocol defined in ISO 7816-3. Communication

speeds up to 153,600 baud are supported by utilizing ISO 7816-3 Protocol and Parame-

ter Selection.

Through dynamic, symmetric-mutual authentication, data encryption, and the use of

encrypted checksums, the AT88SC6416C provides a secure place for storage of sensi-

tive 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 AT88SC6416C is available in industry standard 8-lead packages with

the same familiar pinout as 2-wire serial EEPROMs.

Pin Descriptions

Supply Voltage (V

)

Clock (SCL/CLK)

The V

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

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.

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 V

. 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.

The AT88SC6416C 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

AT88SC6416C does not support the synchronous answer-to-reset sequence.

Device Architecture

User Zones

The EEPROM user memory is divided into 16 zones of 4,096 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.
