Binary Bit Rate Generator

The tag’s data rate is binary programmable in the configuration register to operate at any bit rate

between RF/2 and RF/64.

Memory Section

Memory Map

The physical memory is subdivided into two logical sections (see Figure 2-3). The first logical

memory section contains the 1024 bits of user data. The second logical memory section con-

tains 320 bits of system/configuration data. Both memories are organized in 32-bit data blocks,

each block being equipped with a single lock bit, with which the associated block can be write

protected. Command controlled programming and reading always takes place on a serial MSB

first block basis so that a block constitutes the smallest directly accessible data unit. The user

memory is further subdivided into 8 pages, each of 4 blocks in size. This provides the basis of

the page security scheme (“Password Protection” on page 6).
