MR7930 (新产品) [ROHM]
RFID LSI is a wireless LSI that operates in the UHF band frequency of 860MHz to 960MHz. RFID LSIs are used in fields such as identification tags, taking advantage of the fact that they do not require batteries. LAPIS Technology's RFID LSI is equipped with a sensor function.Ideal for short range battery-less sensor solutions.The frequency that can be used differs for each country. Please adjust the antenna according to the area to be used.;

MR7930/MR793200
UHF band RFID Sensor LSI
OVERVIEW
MR7930/MR793200 is a passive UHF band RFID Sensor LSI for the battery-less short-range IoT devices.
The MR7930/MR793200 is equipped with sensor function to measure electrostatic capacitance.
It is possible to control sensor function by the mandatory command (READ, WRITE) from Reader/Writer (RW ;
interrogator) that is compliant with the international standard EPC global Generation2-Ver.2.0.1 (EPC standard or EPC
Gen2). MR7930 is bump wafer product for inlay tag. MR793200 is package product that has SPI slave interface.

MEMOERY MAP
In compliance with the EPC standard, the MR7930/MR793200’s Memory consists of four banks: Reserved, EPC, TID, and
USER. The USER bank consists of a non-volatile memory “NVM” and a volatile memory “RAM”. It is possible to control
the capacitive sensor functions by accessing “Capacitor monitor1” and “Capacitor monitor2” with READ or WRITE
command.
Also, the MR793200 has the SPI slave interface. It is possible to communicate between the host MCU and RW. However,
RF (EPC) and SPI have different addresses, so be careful.
The address of RF communication from RW assigns by the EPC column of Table 3.
The address of SPI communication from the host MCU assigns by the SPI column of Table 3.
In addition, the MR793200 has a status register for access from the host MCU. For details, refer to the user's manual.

FUNCTION DESCRIPTIONS
The MR7930/MR793200 is equipped with sensor function to measure electrostatic capacitance. Also, the
MR793200 has the SPI slave interface. It is possible to communicate between host MCU and RW.
In this session, there are “Supported Command for RF communication”, “Capacitive Sensor Functions (Measurement and
Comparison)”, “SPI Slave Interface”, and “Arbitration Function”.
● Supported Commands for RF communication
The MR7930/MR793200 supports all mandatory EPC standard commands and some of optional commands as shown in
Table 4. It is possible to control sensor function by the mandatory command (READ, WRITE) from RW.

Capacitive Mesurement Function
The MR7930/MR793200 can measure the electrostatic capacitance of the object connected to CMP pin and CMN pin.
Capacitive measurement function has two modes. There are “Low Range” and “High Range” as shown in Table 5.
It is possible to switch two modes by setting “Sensor mode setting” in the USER bank.

Also, it is possible to control the Capacitive Measurement function by accessing “Capacitor monitor2” with READ
command. The result of Capacitive Measurement is a 12bits binary data. The calculation formula is different for the two
modes.
Measurement time is the reference value between READ command and sensor data response. (BLF = 41 kbps/Miller4)
For details, refer to the user's manual.
●
Capacitive Comparison Function
The MR7930/MR793200 can compare the current capacitance value with the reference value. And it can detect increases
and decreases. This function is Low range mode only.
The reference value and Threshold value (increase or decrease) are stored in “Sensor mode setting”.
Also, it is possible to control the Capacitive Comparison function by accessing “Capacitor monitor2” with READ
command.
The result of Capacitive Comparison function is an 1bit binary data. For details, refer to the user's manual.

●
SPI Slave Interface
When PSEL is “H” (Semi-passive mode), the MR793200 can use SPI Slave Interface to communicate with the host MCU.
As shown in Figure 6, connect the SPI pin (SCK, CSN, SO, SI, IRQN, PSEL) of the MR793200 to the host MCU pin
(Host IF). It is possible to communicate between host MCU and RW by using USER bank (USER memory, RAM0 FLAG,
RAM1 FLAG).
Also, the host MCU can read and write status register of the MR793200. For details, refer to the user's manual.

Arbitration Function
The MR793200 has Arbitration function. It is possible to avoid the collision of access from RW and the host MCU.
As shown in Table 7, SPI_EXCL setting constrains the MR793200 Memory Bank’s access. SPI_EXCL is a register bit in
SPI_STAT (SPI Status Register), and initial value is “0”. Also, MR793200’s Registers can be set only from the host MCU.
In passive mode, the MR7930/MR793200 responds only to RF communication from RW. SPI_EXCL is “0”.
In semi-passive mode, the MR793200 responds to RF communication from RW and SPI communication from the host
MCU.
When SPI_EXCL is set to “0”, it is possible to access memory except for writing to NVM area form the host MCU.
If RW and the host MCU access the MR793200 at the same time, RF communication will be executed first.
When SPI_EXCL is set to “1”, it is possible to access memory by only SPI communication from the host MCU.
Therefore, the MR793200 does not accept access from RW. For details, refer to the user's manual.
