... 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. ...

... 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 7-1.

... Access to the user zones occur only through the control logic built into the device. This logic is configurable through access registers, key registers and keys programmed into the configuration memory during device personalization. Also implemented in the control logic is a cryptographic engine for performing the various higher-level security functions of the device. 5203AS–CRYPT–6/08 AT88SC0404CA [Preliminary 128 Bytes ...

... 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. AT88SC0404CA [Preliminary] 10 5203AS–CRYPT–6/08 ...

... Non-volatile buffering of the data is done automatically by the device. During power-up in applications using Anti-Tearing, the host is required to perform ACK polling in the event that the device needs to carry out the data recovery process. AT88SC0404CA [Preliminary] 12 (1) User Data ...

... Authentication success is memorized and active as long as the chip is powered, unless a new authentication is initialized or RST becomes active. If the new authentication request is not vali- dated, the card loses its previous authentication which must be presented again to gain access. Only the latest request is memorized. 5203AS–CRYPT–6/08 AT88SC0404CA [Preliminary xxxx xxxx ...

... 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”). 13. 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 ...

... The device will respond with a 64-bit ATR code, including historical bytes to indicate the memory density within the CryptoMemory family. Once asynchronous mode has been selected not possible to switch to synchronous mode without first powering off the device. Figure 14-1.
