... The AT88SC0404C provides an ISO 7816-3 compliant asynchronous answer to reset sequence. When the reset sequence is activated, the device will output the data pro- grammed 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 ...

... Configuration Zone Security Fuses AT88SC0404C 4 The configuration zone consists of 2048 bits of EEPROM memory used for storing pass- words, keys and codes and defining security levels to be used for each user zone. Access rights to the configuration zone are defined in the control logic and may not be altered by the user ...

... AT88SC0404C 6 Communications between the device and host operate in three basic modes. Standard mode is the default mode for the device after power-up. Authentication mode is acti- vated by a successful authentication sequence. Encryption mode is activated by a successful encryption activation following a successful authentication. ...

... Checksum (CS) VERIFY CS Write DATA The AT88SC0404C implements a data validity check function in the form of a check- sum, which may function in standard, authentication or encryption modes. In the standard mode, the checksum is implemented as 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 ...
