Memory sector organization
Sector details
The M24LR16E-R user memory is divided into 16 sectors. Each sector contains 1024 bits.
The protection scheme is described in Section 4: System memory area.
In RF mode, a sector provides 32 blocks of 32 bits. Each read and write access is done by
block. Read and write block accesses are controlled by a Sector Security Status byte that
defines the access rights to the 32 blocks contained in the sector. If the sector is not
protected, a Write command updates the complete 32 bits of the selected block.
In I2C mode, a sector provides 128 bytes that can be individually accessed in Read and
Write modes. When protected by the corresponding I2C_Write_Lock bit, the entire sector is
write-protected. To access the user memory, the device select code used for any I2C
command must have the E2 Chip Enable address at 0.
