ST1331d, st1333d 2/ 3 each member of the ST1331d/33d family has an identification data area, unit-counters (with an anti-tearing mechanism for reliable usage in open readers), a post validation certificate, an issuer area (ST1331d) or an authentication secret key area (st1333d), and a user area. this is summarized in figure 4. the validation certificate allows the recognition of the device by the appropriate security module. when the 8 times reloadable option is activated, the certificate and the reload counter (address 64d to 71d) can be used to allow the recognition of the circuit by the appropriate security module. this will allow the development of a reloadable card as the certificate value is refreshed each time the reload counter is incremented. the anti-tearing mechanism guards against mis- counts occurring when the card is prematurely extracted, while an operation is underway, in an open reader. modes the device works in two distinct modes of operation: ? issuer mode: for the card manufacturer. allowing custom data to be written to the device, to initialize it before release to the end user. ? user mode: for the end user of the card, with restricted, and controlled access to the device. before delivery, from st to the card issuer, the device is placed in the issuer mode. this operation is performed by blowing the ? test fuse ? . options three options are available when ordering the device: ? the anti-tearing mechanism can be disconnected. in this case, the anti-tearing flag area from bit 288d to bit 319d is unused (figure 3). ? the user area, from bit 320d to bit 375d, can be defined as ? not erasable ? in the user mode. ? the reload mechanism can be activated. in this case, erasing a bit in the reload counter refreshes the certificate (cer). at this time, the certificate can be programmed with a new value. ordering information the notation used for the device number is as shown in table 10. for a list of available options (speed, package, etc.) or for further information on any aspect of this device, please contact your nearest st sales office. table 2. ordering information scheme note: please contact your nearest st sales office to check on availability example: st1333 d w4 / xx yy product transport code 33 active authentication function given by st 31 issuer area customer code given by the issuer revision delivery form d 5 v supply voltage, fuse blow and inlock system d10 micromodule on reel w4 wafer (180 m thickness)
