■ DESCRIPTION
The MB89R112 is an LSI device that has built-in high-speed, large-capacity FRAM and is used for vicinity-
RFID.
Note : FerVID family is a trademark of Fujitsu Semiconductor Limited, Japan.
■ FEATURES
• Memory capacity of 9 Kbytes FRAM (including 8192 bytes of user area)
• 32-byte/block configuration, 256 blocks
• High-speed data transmission and reception 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
• Data Retention : 10 years ( + 85 °C)
• 64-bit UID
• FRAM memory data protection
• Compliance with ISO/IEC 15693 (partly not supported)
• Compliance with ISO/IEC 18000-3 (Mode 1) (partly not supported)
• Serial Interface(SPI)
- Accessible area: User memory area can be read/written through SPI.
- Access control with RF interface is prioritized
- Power supply : 3.3 V (power is required for the memory access via SPI.)
- Low power consumption: Operating current = 97 μA@2 MHz (Typ)
Standby current = 25 μA (Typ)
- Power down mode: Power down current = 10 nA (Typ)
- Package: 24-pin QFN (LCC-24P-M64)

4. Arbitration between RF and SPI communication
This LSI has access arbitration feature when there is access from both RF I/F and SPI I/F simultaneously.
In this case, RF communication has priority.
BUSY signal indicates that there is access from RF I/F, and it is validated when VDD is connected.
The controller needs to confirm the BUSY signal before changing to the SPI communication mode. When
the BUSY signal is in “H”, the SPI communication is ignored if the SPI communication is performed at the
same time because the LSI is executing RF communication.
The BUSY pin outputs “H” if the VDD pin is turned on during RF communication as the figure shown below.

3. Lock Area
The following figure shows the area of Block Security Status and Read Lock Status of RF communication
command, SPI Read Lock and SPI Write Lock of SPI communication command.
Lock Status “1” means Lock state, and Lock Status “0” means the state where it does not lock.
