AT88SC0104C
2021BS–SMEM–10/02
Description
The AT88SC0104C member of the CryptoMemory family is a high-performance secure
memory providing 1 Kbit of user memory with advanced security and cryptographic fea-
tures built in. The user memory is divided into 4 zones, each of which may be
individually set with different security access rights or combined together to provide
space for 1 to 4 data files. The AT88SC0104C provides high security, low cost and ease
of implementation for smart card applications without the need for a microprocessor
operating system. The embedded cryptographic engine provides for a dynamic, sym-
metric-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 AT88SC0104C offers the
ability to communicate with virtually any smart card reader using the asynchronous T = 0
protocol defined in ISO 7816-3. For closed systems or applications using the device on
a circuit board, the AT88SC0104C will also communicate using a synchronous two-wire
protocol at clock speeds up to 1.5 MHz. In this communication mode, up to 15 devices
may be connected and individually addressed on the same serial data bus. The two-wire
protocol may also be used for high-speed personalization of the device in card form.

Pin Descriptions
Supply Voltage (V
CC
)
The V
CC
input is a 2.7V to 5.5V positive voltage supplied by the host.
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.
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
CC
. 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.
Reset (RST)
The AT88SC0104C provides an ISO 7816-3 compliant asynchronous answer to reset
sequence. When the reset sequence is activated, the device will output the data pro-
