1. 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 effectively combined together to
provide space for one to sixteen data files.
1.1. Smart Card Applications
The AT88SC6416C 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 AT88SC6416C 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.
1.2. Embedded Applications
Through dynamic and symmetric mutual authentication, data encryption, and the use of encrypted checksums, the
AT88SC6416C 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 AT88SC6416C is available
in industry standard 8-lead packages with the same familiar pinout as 2-wire serial EEPROMs.

2. Pin Descriptions
2.1. Supply Voltage (V
CC
)
The V
CC
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 AT88SC6416C 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
AT88SC6416C 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.
