Description

1.1

Memory mapping

The LRI2K is divided into 64 blocks of 32 bits. Each block can be individually write-protected

using the Lock command.

The User area consists of blocks that are always accessible in read mode. Write operations

are possible if the addressed block is not protected. During a write operation, the 32 bits of

the block are replaced by the new 32-bit value.

The LRI2K also has a 64-bit block that is used to store the 64-bit unique identifier (UID). The

UID is compliant to the ISO 15963 description, and its value is used during the anticollision

sequence (Inventory). This block is not accessible by the user and its value is written by ST

on the production line.

The LRI2K also includes an AFI register in which the application family identifier is stored,

and a DSFID register in which the data storage family identifier used in the anticollision

algorithm is stored. The LRI2K has an additional 32-bit block in which the kill code is stored.
