Description  
The AT88SC25616C member of the CryptoMemory family is a high-performance secure  
memory providing 256 Kbits of user memory with advanced security and cryptographic  
features built in. The user memory is divided into 16 2-byte 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.  
Smart Card Applications The AT88SC25616C 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 AT88SC25616C 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 AT88SC25616C 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 AT88SC25616C 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 negative edge clock data out of the device.
