A ferroelectric random access organized as 128K 8 14 memory or F-RAM is nonvolatile and performs reads and writes High-endurance 100 trillion (10 ) read/writes similar to a RAM. It provides reliable data retention for 151 years 151-year data retention (See Data Retention and Endurance while eliminating the complexities, overhead, and system-level on page 13) reliability problems caused by EEPROM and other nonvolatile NoDelay writes memories. Advanced high-reliability ferroelectric process 2 Unlike EEPROM, the FM24V10 performs write operations at bus Fast two-wire Serial interface (I C) speed. No write delays are incurred. Data is written to the Up to 3.4-MHz frequency memory array immediately after each byte is successfully 2 Direct hardware replacement for serial (I C) EEPROM transferred to the device. The next bus cycle can commence Supports legacy timings for 100 kHz and 400 kHz without the need for data polling. In addition, the product offers substantial write endurance compared with other nonvolatile Device ID and Serial Number memories. Also, F-RAM exhibits much lower power during writes Manufacturer ID and Product ID than EEPROM since write operations do not require an internally Unique Serial Number (FM24VN10) elevated power supply voltage for write circuits. The FM24V10 is 14 Low power consumption capable of supporting 10 read/write cycles, or 100 million times 175 A active current at 100 kHz more write cycles than EEPROM. 90 A (typ) standby current These capabilities make the FM24V10 ideal for nonvolatile 5 A (typ) sleep mode current memory applications, requiring frequent or rapid writes. Examples range from data logging, where the number of write Low-voltage operation: V = 2.0 V to 3.6 V DD cycles may be critical, to demanding industrial controls where the Industrial temperature: 40 C to +85 C long write time of EEPROM can cause data loss. The 8-pin small outline integrated circuit (SOIC) package combination of features allows more frequent data writing with less overhead for the system. Restriction of hazardous substances (RoHS) compliant The FM24V10 provides substantial benefits to users of serial 2 (I C) EEPROM as a hardware drop-in replacement. The FM24VN10 is offered with a unique serial number that is read-only and can be used to identify a board or system. Both devices incorporate a read-only Device ID that allows the host to determine the manufacturer, product density, and product revision. The device specifications are guaranteed over an industrial temperature range of 40 C to +85 C. For a complete list of related documentation, click here.
