3 / 3 page 3/3 ST1335, ST1336, ST1355 card is unexpectedly extracted, while an operation is underway, in an open reader. EXTERNAL COMMANDS The device uses five contacts: VCC, GND, I/O, CLK, RST. Four commands distinct can be composed using these external pins: – RESET: to reset the internal address register to 000d – READ: to increment the internal address register and read the data bit at the new address – COMPARE: to allow comparison of the presented code against the internal transport code – PROGRAM: to program the bit at the current address CONFIGURATIONS The device works in two distinct configurations: – Issuer Configuration: for the card manufacturer. Customized data can be written to the chip, to initialize it before release to the end user. – User Configuration: for use by the end user of the card, but with restricted access. OPTIONS Three options can be chosen on 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 2). – The user area, from bit 320d to bit 375d, can be defined as “not erasable” in the User Configuration. – 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 2. 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: 1. Please contact your nearest ST Sales Office to check on availability Example: ST1335 –C W4 / XX YY Product Transport Code 35 Active Authentication Function Given by ST 36 Issuer Area 55 Cipher Block Chaining Authentication Function Customer Code Given by the Issuer Fuse Blow Voltage Delivery Form B6 V1 D10 Micromodule on reel C 5 V1 D15 Micromodule on reel W4 Wafer (180 µm thickness) W2 Wafer (280 µm thickness) |
