Mouser offers inventory, pricing, & datasheets for I2C F-RAM. New I2C Interface 1Mbit FRAM Product Release Unlike SRAM, FRAM does not lose the data when power is lost. Stand-alone FRAM memory,which has high degree of compatibility with SRAM because of its Pseudo-SRAM I/F, can be a substitution of SRAM. Fujitsu Semiconductor provides FRAM products with serial (I 2 C and SPI) and parallel interface, and 4Kbit to 4Mbit products are now available in production. Fujitsu is offering the engineering samples or production samples for customer evaluation. FRAM, F-RAM or FeRAM (Ferroelectric Random Access Memory) is nonvolatile RAM memory that combines the advantages of both RAM and nonvolatile memory like Flash and EEPROM. filters up to 98%* of dust, pollen and other contaminants. These FRAM products are offered in industry-standard 8-pin SOP packages, so they can replace EEPROMs or serial Flash memories, used in applications such as factory-automation, metering, and industrial equipment, without the major change in the PCB design. Figure2: Power Comparison at WritingThe product operates at the voltage between 1.8 and 3.3V in the temperature range between -40 and 85 C. As to operation frequency, the product supports "high-speed" mode, which enables read and write at 3.4MHz, as well as 1MHz operation, the same speed as conventional EEPROMs. This makes it run slower than I want it to, especially since I'm using the memory to keep camera pixel information and I need to process it quickly. One works with SPI bus and the other uses I2C. We picked up the largest chip that has I2C and is also 5V compliant.

I2C_EEPROM: Library for I2C EEPROMS. It is good in high-speed writing, high endurance and low power operation. Furthermore, applications that have used other products with I2C interfaces, such as EEPROMs and microcontrollers, can now replace EEPROMs, with the new FRAM products, enabling high-precision data capture through high-frequency logging (Figure 1) and reducing the power consumption during the data writing (Figure 2). Works for 1M devices when considering â¦ In future, we will develop our technology to improve specs such as operation voltage and access speed, and provide a variety of products. The addition of the MB85RC1MT extends the line of FRAM products with the I2C interface to cover the range from 4Kbit to 1Mbit, and those with the SPI interface from 16Kbit to 2Mbit (FRAM Product Lineup). The FlashStorage library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory of microcontrollers. I'm using the Adafruit I2C FRAM breakout board with my Nano and it works as advertised, but every time I write a variable to this thing I have to use library function calls with addressing. Stock 92 $27.88 . I2C Ferroelectric Random Access Memory (FRAM). Figure1: Guaranteed Write Cycle Comparison FRAM is a type of memory that features both non-volatility, which allows data to be retained even when the power is switched off, and random access, which enables fast data writing. The new product is guaranteed for up to 10 trillion read/write cycles, and is optimum for use in applications requiring frequent rewriting of the data, such as real-time data logging for factory-automation, metering, and industrial equipment. However, it is much faster than Flash - and you don't have to deal with writing or erasing pages. The FM24V05 provides substantial benefits to users of serial (I2C) EEPROM as a hardware drop-in replacement. Fujitsu is offering the engineering samples or production samples for customer evaluation. Like SPI, I2C is synchronous, so the output of bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave. Since Fujitsu Semiconductor began mass production of FRAM products in 1999, these features of FRAM have led to their wide use in such applications as factory-automation equipment, instrumentation, financial terminals, and medical devices.
