USER MANUAL
STM 550 / EMSI – ENOCEAN MULTISENSOR FOR IOT APPLICATIONS
© 2020 EnOcean | www.enocean.com F-710-017, V1.0 STM 550 / EMSI User Manual | v1.4 | November 2020 | Page 48/97
9 NFC registers
The NFC memory is organized in pages (smallest addressable unit) where each page contains
4 byte of data. Several pages with similar functionality form an NFC memory area.
9.1 NFC memory areas
These NFC pages are allocated into the following areas:
◼ Device Identification NDEF string (Public read-only access; no PIN required)
This area contains an NDEF string identifying key device parameters
◼ User Information NDEF string (Public read / write access; no PIN required)
This area allows any user to read or write information about the device such as the
intended installation location or additional instructions
◼ PUBLIC INFO (Public read-only access; no PIN required)
This area contains key device parameters in binary format
◼ NFC HEADER (Public read-only access; no PIN required)
This area contains information about the NFC revision
◼ INTERNAL DATA (Non-accessible)
This area contains calibration values and internal parameters and cannot be used
◼ CONFIGURATION (Read and Write access, PIN required)
This area contains device configuration registers
◼ USER DATA (Read and Write access, PIN required)
This area allows the user to store up to 64 byte of data such as information about the
installation or any other data that the user deems relevant.
STM 550 does not use this area and does not interpret its content in any way.
The organization of the STM 550 NFC memory map is shown in Table 8 below.
