One URL record M24SR memory (1) The CC file gives some information about the M24SR and the NDEF file (access conditions etc.). This file is a read-only file for the RF or I²C host and cannot be modified by issuing a write command. (2) The system file is a ST proprietary file. It can be read by the RF or I²C host and written by the I²C host. 8 · Data protection thanks to a password. Why ? · To lock an NDEF file · Password size: 128 bits · 3.4 1038 possibilities to find the right password · 2 passwords, · One for read access · One for write access · Possible to lock permanently in read or write access · 2 bytes in the CC file are used to define the Read and Write access rights to the NDEF file. Data protection Unlocked Read or Locked Write not autorized Permanent Lock 9 GPO feature · The configurable output signal (GPO) pad is mainly to wake-up or inform a micro-controller about one event. It's an open drain pad so external pull-up resistor to Vcc is required. · 7 possible configurations · Session Open · An RF or I²C session ongoing · MIP (NDEF Message updating In Progress) · RF host writing an NDEF length different from 0x0000. This mode can be used to detect when the RF host changes the NDEF message as defined by NFC Forum · WIP (Writing In Progress) · M24SR is executing a writing operation · INT (interrupt) RF disable 1 8 Vcc · RF or I²C host can force M24SR to send a negative pulse on the pin · State mode AC0 2 AC1 3 7 GPO 6 SCL · RF or I²C host can control the state of the GPO pad during the RF session · I²C ready response Vss 4 5 SDA · An I²C response is ready to be read by the I²C host · RF busy · RF host is communicating with M24SR 10 I²C interface · I²C interface is typically used for connecting M24SR to a microcontroller.
