... ISO 7816-3. Through dynamic and symmetric mutual authentication, data encryption, and the use of encrypted checksums, the AT88SC0204C provides a secure place for storage of sensi- tive information within a system. With its tamper detection circuits, this information remains safe even under attack. A 2-wire serial interface running at 1.0 MHz is used for fast and efficient communications with devices that may be individually addressed ...

... IL IH 2022HS–SMEM–04/07 The AT88SC0204C 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. The AT88SC0204C does not support the synchronous answer-to-reset sequence ...

... Figure 6. Start and Stop Definitions Figure 7. Output Acknowledge Device Architecture User Zones AT88SC0204C 6 The EEPROM user memory is divided into 4 zones of 512 bits each. Multiple zones allow for different types of data or files to be stored in different zones. Access to the user zones is allowed only after security requirements have been met. These security requirements are defined by the user during the personalization of the device in the con- figuration memory ...

... The configuration memory consists of 2048 bits of EEPROM memory used for storing passwords, keys and codes and for defining security levels to be used for each user zone. Access rights to the configuration memory are defined in the control logic and may not be altered by the user. AT88SC0204C $ ...

... Fuses are designed for the module manufacturer, card manufacturer and card issuer and should be blown in sequence, although all programming of the device and blowing of the fuses may be performed at one final step. The AT88SC0204C supports two different communication protocols. • Smart Card Applications: The asynchronous protocol defined by ISO 7816-3 is used for compatibility with the industry’ ...

... Programming AT88SC0204C 12 The AT88SC0204C 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 ...
