FM24V01 2 128-Kbit (16 K 8) Serial (I C) F-RAM 128-Kbit (16 K 8) Serial (I2C) F-RAM Features Functional Description The FM24V01 is a 128-Kbit nonvolatile memory employing an 128-Kbit ferroelectric random access memory (F-RAM) advanced ferroelectric process. A ferroelectric random access logically organized as 16 K 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 the Data Retention and while eliminating the complexities, overhead, and system-level Endurance table) reliability problems caused by EEPROM and other nonvolatile NoDelay writes memories. Advanced high-reliability ferroelectric process 2 Unlike EEPROM, the FM24V01 performs write operations at bus Fast 2-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 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 Low power consumption elevated power supply voltage for write circuits. The FM24V01 is 14 90 A (typ) active current at 100 kHz capable of supporting 10 read/write cycles, or 100 million times 80 A (typ) standby current more write cycles than EEPROM. 4 A (typ) sleep mode current These capabilities make the FM24V01 ideal for nonvolatile Low-voltage operation: V = 2.0 V to 3.6 V memory applications, requiring frequent or rapid writes. DD Examples range from data logging, where the number of write Industrial temperature: 40 C to +85 C cycles may be critical, to demanding industrial controls where the 8-pin small outline integrated circuit (SOIC) package long write time of EEPROM can cause data loss. The combination of features allows more frequent data writing with Restriction of hazardous substances (RoHS) compliant less overhead for the system. The FM24V01 provides substantial benefits to users of serial 2 (I C) 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 documentation, click here.
