The two-byte CRC is present in every request and in every answer frame, before the EOF. The CRC is calculated on all the bytes between SOF (not included) and the CRC field. ...

... Memory mapping 4 Memory mapping The SRIX4K is organized as 128 blocks of 32 bits as shown in accessible by the Read_block command. Depending on the write access, they can be updated by the Write_block command. A Write_block updates all the 32 bits of the block. Figure 12. SRIX4K memory mapping Msb Block Addr b 31 ...
Page 15
... The five 32-bit blocks making up the resettable OTP area can be erased in one go by adding an auto-erase cycle to the Write_block command. An auto-erase cycle is added each time the SRIX4K detects a Reload command. The Reload command is implemented through a specific update of the 32-bit binary counter located at block address 6 (see ...

... The counter with block address 6 controls the Reload command used to reset the resettable OTP area (addresses 0 to 4). Bits b of these 11 bits is updated, the SRIX4K detects the change and adds an Erase cycle to the Write_block command for locations (see Erase cycle remains active until a Power-off or a Select command is issued. The SRIX4K’s resettable OTP area can be reloaded up to 2,047 times (2 4 ...

... System area This area is used to modify the settings of the SRIX4K. It contains 3 registers: OTP_Lock_Reg, Fixed Chip_ID and ST Reserved. See A Write_block command in this area will not erase the previous contents. Selected bits can thus be set from All bits previously at 0 remain unchanged. Once all the 32 bits of a block are at 0, the block is empty and cannot be updated any more ...

... SRIX4K (wrong command or CRC error), the memory does not return any error code. When a valid frame is received, the SRIX4K may have to return data to the reader. In this case, data is returned using BPSK encoding, in the form of 10-bit characters framed by an SOF and an EOF ...
Page 21
... The SRIX4K can be switched into different states. Depending on the current state of the SRIX4K, its logic will only answer to specific commands. These states are mainly used during the anticollision sequence, to identify and to access the SRIX4K in a very short time. The SRIX4K provides 6 different states, as described in the following paragraphs and in Figure 20 ...

... SRIX4K. The purpose of the anticollision sequence is to allow the reader to select one SRIX4K at a time. The SRIX4K is given an 8-bit Chip_ID value used by the reader to select only one among up to 256 tags present within its field range. The Chip_ID is initialized with a random value during the Ready state, or after an Initiate() command in the Inventory state ...

Description of an anticollision sequence The anticollision sequence is initiated by the Initiate() command which triggers all the SRIX4K devices that are present in the reader field range, and that are in Inventory state. Only SRIX4K devices in Inventory state will respond to the Pcall16() and Slot_marker(SN) anticollision commands. ...

... Anti-clone function The SRIX4K provides an anti-clone function that allows the application to authentication the device. This function uses reserved data that is stored in the SRIX4K memory at its time of manufacture. The Authentication system is based on a proprietary challenge/response mechanism which allows the application software to authenticate any member of the secure memory tag SRXxxx family from STMicroelectronics (of which the SRIX4K is the prime example) ...

... Initiate() command, all SRIX4K devices in Ready state switch to Inventory state, set a new 8-bit Chip_ID random value, and return their Chip_ID value. This command is useful when only one SRIX4K in Ready state is present in the reader field range. It speeds up the Chip_ID search process. The Chip_slot_number is not used during Initiate() command access ...
Page 30
... If not, the SRIX4K does not send any response. The Pcall16() command, used together with the Slot_marker() command, allows the reader to search for all the Chip_IDs when there are more than one SRIX4K device in Inventory state present in the reader field range. ...

Page 32
... Select(Chip_ID) command Command code = 0Eh The Select() command allows the SRIX4K to enter the Selected state. Until this command is issued, the SRIX4K will not accept any other command, except for Initiate(), Pcall16() and Slot_marker(). The Select() command returns the 8 bits of the Chip_ID value. An SRIX4K in Selected state, that receives a Select() command with a Chip_ID that does not match its own is automatically switched to Deselected state ...
Page 33
... On receiving the Completion() command, an SRIX4K in Selected state switches to Deactivated state and stops decoding any new commands. The SRIX4K is then locked in this state until a complete reset (tag out of the field range). A new SRIX4K can thus be accessed through a Select() command without having to remove the previous one from the field ...
Page 34
... On receiving the Reset_to_inventory() command, all SRIX4K devices in Selected state revert to Inventory state. The concerned SRIX4K devices are thus resubmitted to the anticollision sequence. This command is useful when two SRIX4K devices with the same 8- bit Chip_ID happen Selected state at the same time. Forcing them to go through the anticollision sequence again allows the reader to generates new Pcall16() commands and so, to set new random Chip_IDs ...

The address byte gives access to the 128 blocks of the SRIX4K (addresses 0 to 127).
