3.2.3

Both Microcontroller and RFID reader are available during setup

The setup process starts exactly as in Section 3.2.1: Microcontroller only is available during

setup.

Once the bank UIDs are programmed in the mapping area, an RF operation can be

performed in order to further speed up RF communications by programming the bank UID

number stored in the DSFID area. As the DSFID content of each M24LR64-R device (bank)

is available during the inventory round, an RFID reader immediately knows with which

device it will communicate.

Figure 12.

The following operation is to be performed with an ISO 15693 RFID reader supporting the

M24LR64-R device, and by placing only one Multi-Bank card (ANT4-M24LR-A or ANT5-

M24LR-A) at a time in the RF reader's field:

●

Perform an RF Inventory round.

●

Read the last block of each bank until reaching the mapping area.

●

Read the UID value for each bank:

UID 0 = BANK 0

UID 1 = BANK 1

UID 2 = BANK 2

UID 3 = BANK 3
