The MB89R118C is a vicinity type of RFID LSI device embedded with 2 Kbytes FRAM, which enables fast and frequent write operation.
Features
• Memory capacity of 2 Kbytes FRAM (including 2000 bytes of user area)
• 8-byte/block configuration, 256 blocks
• High-speed data transmission at 26.48 kbps
• Fast command supported (data transmission at 52.97 kbps) (Transponder Reader/Writer)
• Carrier frequency at 13.56 MHz
• Anti-collision function : 30 tags per second
• Read/Write endurance : 1012 times
FRAM Configuration The FRAM has 2000 bytes for use as user area and 48 bytes for use as system area. The FRAM memory areas consist
of a total of 256 blocks (250 blocks of user area and 6 blocks of system area). Each block can store 64 bits (8 bytes) of data.
The block is the unit used for the writing and reading of FRAM data. The memory configuration of FRAM is shown below.
• Data retention : 10 years ( + 85 °C) , 30 years (+70 °C)
• 64-bit UID
• FRAM memory data protection
• Electronic article surveillance (EAS) command
• Transmission protocol based on ISO/IEC 15693, ISO/IEC18000-3 (Mode 1) (*)
FRAM memory configuration
Blocks “00H” to “F9H” are user area. The user area is defined as an area that can be accessed when the
corresponding block address is specified. On the other hand, Blocks “FAH” to “FFH” are system area. The
system area is defined as an area that can be accessed only with a specific command.
The system area consists of 6 blocks and contains UID, AFI, DSFID, EAS bits, and security status (can write
or cannot write) data for individual block. UID is fixed and cannot be updated. AFI, DSFID, and EAS bits are
written at the factory, and can be updated and locked (disable to write) with commands (Only EAS bit cannot
be locked) .
As shown in above, “FAH” holds the UID, and “FCH” to “FFH” hold the security status information on individual
user areas.
The configuration of “FBH” to “FFH” blocks is shown below. “FBH” block is used for EAS status, AFI and DSFID
data, the security status data of AFI and DSFID. “FCH” to “FFH” blocks contain block security status data.

As high-speed data communication advances and data is transmitted more frequently, the need for non-volatile memory that can withstand such frequent data recording operation increases. In addition, faster writing speed that enables data to be recorded without error even in the event of a sudden power outage by an accident is required for memory. Fujitsu FRAM is one of memory devices with the features of high read/write endurance and fast writing speed required in this new era of IoT, automotive, industrial(for facility and infrastructure), smart meters, enterprise, consumer, medical, networking.
