NFC transponders combine a near-field communication (NFC) interface with a programmable microcontroller, non-volatile FRAM, analog-to-digital converter, SPI, or I2C interface. Optimized for use in fully passive (battery-less) mode or semi-active mode for longer battery life in a wide range of consumer wearable, industrial, medical, and asset tracking applications.
Non-volatile FRAM combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash memory, while delivering the industry's lowest power consumption and virtually unlimited writes. FRAM meets the needs of developers creating products that can quickly store sensor data and easily configure transponders and sensors for any application. If there is demand, Guoxin Sichen can provide stable supply channels and advantages.
Application advantages of domestic FRAM PB85RS2MC in NFC transponder:
1. PB85RS2MC is configured as 262,144 8-bit, which is a non-volatile memory cell formed by ferroelectric process and silicon gate CMOS process technology, and the chip does not need a battery to hold data.
2. PB85RS2MC has the advantages of fast read and write speed (up to 1 million times), long write life, and low write energy consumption.
3. The minimum power consumption of PB85RS2MC is 9 microamperes (standby), and the working voltage is 27 volts to 36 volts, can operate in a temperature range of -40 -85.
4. PB85RS2MC has a capacity of 2M bit, provides SPI interface, works at a frequency of 25 MHz, and supports 40MHz high-speed read command.
5. PB85RS2MC working environment temperature range -40 to 85, package is 8-pin SOP package, RoHS compliantPerformance compatible with MB85RS2MT (Fujitsu) and FM25V20A (Cypress).
NFC transponders support maintenance-free designs and hermetically sealed galvanic isolation sensor systems in the industrial market that rely on RF field power and communicate wirelessly via NFC to collect and record data. In medical or health & fitness applications, it can also be used for patients to monitor important data and share it with those responsible for their own health. The device monitors and records the data in local memory (FRAM) before transferring it to an NFC-enabled tablet or smartphone.
