... Upon activation of the reset sequence, the device outputs bytes contained in the 64- bit Answer-To-Reset register. An internal pull-up on the RST input pad allows the device to oper- ate in synchronous mode without bonding RST. The AT88SC0404CA does not support an Answer-To-Reset sequence in the synchronous mode of operation. ...

... Memory Reset After an interruption in communication due protocol errors, power loss or any reason, perform "Acknowledge Polling" to properly recover from the condition. Acknowledge polling consists of sending a start condition followed by a valid CryptoMemory command byte and determining if the device responded with an ACKNOWLEDGE. Figure 8-1.

... The configuration memory consists of 2048 bits of EEPROM memory used for storage of pass- words, keys, codes, and also used for definition of security access rights for the user zones. Access rights to the configuration memory are defined in the control logic and are not alterable by the user after completion of personalization. ...

... Cryptographic Message Authentication Codes AT88SC0404CA implements a data validity check function in the standard, authentication or encryption modes of operation. In the standard mode, data validity check is done through a Modification Detection Code (MDC), in which the host may read an MDC from the device in order to verify that the data sent was received correctly ...

... For a user zones protected by this feature, data can only be programmed (bits change from a “1” “0”), but not erased (bits change from a “0” “1”). 14. Protocol Selection The AT88SC0404CA supports two different communication protocols. Smartcard Applications: Smartcard applications use ISO 7816-B protocol in asynchronous mode for compatibility and interoperability with industry standard smartcard readers ...
