... SOIC or, PDIP 1. Description The AT88SC153 provides 2,048 bits of serial EEPROM memory organized as one configuration zone of 64 bytes and three user zones of 64 bytes each. This device is optimized as a “secure memory” for multiapplication smart card markets, secure identification for electronic data trans- fer, or components in a system without the requirement of an internal microprocessor ...

... Bit 7 0 When the fuses are all “1”s, read and write are allowed in the entire memory. Before blowing the FAB fuse, Atmel writes the entire memory to “1” and programs the fabrication subzone (except CMC and AR) and the secure code. ...

... Each access register may point to a unique password set, or access registers for multiple zones may point to the same password set. In this case, verification of a single password will open several zones, combining the zones into a single larger zone. AT88SC153 6 Access Registers ...

The 64-bit secret seed, defined by the issuer, is diversified as a function of the identification number. 6.10 Memory Test Zone The memory test zone is an 8-bit free access zone for memory and protocol test. 6.11 Password Set The password set consists of two sets of two 24-bit passwords for read and write operations, defined by the issuer ...

... Programmable Chip Select (CS0–CS3): The four most significant bits (b4–b7) of every com- mand comprise the chip select address. All AT88SC153 devices will respond to the default chip select address of $B (1011). Each device will also respond to a second chip select address pro- grammed into CS0– ...

... The current password is memorized and active until power is turned off, unless a new password is presented or RST becomes active. Only one password is active at a time. The AT88SC153 requires that the Verify Password command be transmitted twice in sequence to successfully verify a write or read password ...

... Read Fuses Figure 9-3. Note: The Read Fuses operation is always allowed. The AT88SC153 will continuously transmit the fuse byte if the host continues to transmit an ACK. The command is terminated when the host transmits a NACK and STOP bit. 9.4 Write Fuses Figure 9-4. Note: The Write Fuses operation is only allowed under secure code control; no data byte is transmitted by the host. The fuses are blown sequentially: CMA is blown if FAB is equal to “ ...

... PAC corresponding to the “r” and “p” bits. The data bits in this initial- ization command are ignored. The second Verify Password command will compare the 3-byte password data presented with the corresponding password value stored in memory. If the com- parison is valid, the PAC will be cleared. For both commands, once the command sequence is completed and a stop condition is issued, a nonvolatile write cycle is initiated to update the asso- ciated attempts counter ...

This happens during the ninth clock cycle. 10.5 Standby Mode The AT88SC153 features a low-power standby mode that is enabled upon power-up and after the receipt of the stop bit and the completion of any internal operations. 10.6 Acknowledge Polling Once the internally-timed write cycle has started and the device inputs are disabled, acknowl- edge polling can be initiated ...
