An F-RAM is nonvolatile and logically organized as 16K 8 14 performs reads and writes similar to a RAM. It provides reliable High-endurance 100 trillion (10 ) read/writes data retention for 151 years while eliminating the complexities, 151-year data retention (See Data Retention and Endurance overhead, and system-level reliability problems caused by on page 13) EEPROM and other nonvolatile memories. NoDelay writes Unlike EEPROM, the FM24V01A performs write operations at Advanced high-reliability ferroelectric process bus speed. No write delays are incurred. Data is written to the 2 Fast two-wire serial interface (I C) memory array immediately after each byte is successfully 1 Up to 3.4-MHz frequency transferred to the device. The next bus cycle can commence Direct hardware replacement for serial EEPROM without the need for data polling. In addition, the product offers Supports legacy timings for 100 kHz and 400 kHz substantial write endurance compared with other nonvolatile memories. F-RAM also exhibits much lower power during writes Device ID than EEPROM because write operations do not require an Manufacturer ID and Product ID internally elevated power supply voltage for write circuits. The 14 Low power consumption FM24V01A is capable of supporting 10 read/write cycles, or 175- A active current at 100 kHz 100 million times more write cycles than EEPROM. 150- A standby current These capabilities make the FM24V01A ideal for nonvolatile 8- A 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 combination of features allows more frequent data writing with 8-pin small outline integrated circuit (SOIC) package less overhead for the system. Restriction of hazardous substances (RoHS) compliant The FM24V01A provides substantial benefits to users of serial EEPROM as a hardware drop-in replacement. The device incorporates 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 resources, click here.
