ST25TA64K memory management

3.1

Memory structure

The ST25TA64K supports the NDEF Tag Application as defined in the NFC Forum Type 4

Tag. The ST25TA64K is composed of three files:

•

one Capability Container file;

•

one NDEF file;

•

one System file: this is an ST-proprietary file.

The System file contains some information on the configuration of the ST25TA64K device.

The CC file gives some information about the ST25TA64K itself and the NDEF file. The

NDEF file contains the User data.

3.1.1

File identifier

The file identifier is the value used in the Select command to select a file.

3.1.2

CC file layout

The CC file gives some information about the ST25TA64K and the NDEF file. This file is a

read-only file for the RF host and cannot be modified by issuing a write command.

The T field, Read Access and Write Access fields can be changed by the RF host by issuing

a specific process (refer to Section 7: Functional procedures).
