Memory allocation of the MDS
Memory division for PC applications of ISO 15693 transponders
The MDS D1xx are based on the NXP I-Code SL2 and have a 128-byte EEPROM memory
that is subdivided into 32 blocks. A block on the transponder is the smallest addressable
memory area and is subdivided into areas of 4 bytes in length for access. 112 bytes (= 28
blocks) can be used by the user.
The MDS D2xx are based on the Texas HF-I and have a 256-byte EEPROM memory that is
subdivided into 64 blocks. A block on the transponder is the smallest addressable memory
area and is subdivided into areas of 4 bytes in length for access. All 256 bytes (= 64 blocks)
can be used by the user.
The MDS D3xx are based on the Infineon SRF55V10P and have a 1024-byte EEPROM
memory that is subdivided into 256 blocks. A block on the transponder is the smallest
addressable memory area and is subdivided into areas of 4 bytes in length for access. 992
bytes (= 248 blocks) can be used by the user.
The MDS D4xx are based on the Fujitsu MB89R118B and have a 2048-byte FRAM memory
that is subdivided into 256 blocks. A block on the transponder is the smallest addressable
memory area and is subdivided into areas of 8 bytes in length for access. 2000 bytes (= 250
blocks) can be used by the user.
