1 / 12 page Preliminary This is a product that has fixed target specifications but are subject Ramtron International Corporation to change pending characterization results. 1850 Ramtron Drive, Colorado Springs, CO 80921 (800) 545-FRAM, (719) 481-7000 http://www.ramtron.com Rev. 1.0 Aug. 2006 Page 1of 12 FM24C512 512Kb FRAM Serial Memory Features 512Kbit Ferroelectric Nonvolatile RAM Organized as 65,536 x 8 bits High Endurance 10 Billion (10 10) Read/Writes 45 year Data Retention NoDelay Writes Advanced High-Reliability Ferroelectric Process Fast Two-wire Serial Interface Up to 1 MHz Maximum Bus Frequency Supports Legacy Timing for 100 kHz & 400 kHz Low Power Operation 5V Operation 250 A Active Current (100 kHz) 120 A Standby Current Industry Standard Configuration Industrial Temperature -40 C to +85 C 8-pin Green /RoHS EIAJ SOIC Package Description The FM24C512 is a 512-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 45 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM24C512 performs write operations at bus speed. No write delays are incurred. The next bus cycle may commence immediately without the need for data polling. In addition, the product offers write endurance orders of magnitude higher than EEPROM. Also, FRAM exhibits much lower power during writes than EEPROM since write operations do not require an internally elevated power supply voltage for write circuits. These capabilities make the FM24C512 ideal for nonvolatile memory applications requiring frequent or rapid writes. Examples range from data collection where the number of write cycles may be critical, to demanding industrial controls where the long write time of EEPROM can cause data loss. The combination of features allows more frequent data writing with less overhead for the system. The FM24C512 is available in an 8-pin EIAJ SOIC package using an industry standard two-wire protocol. Ramtron s green packages are RoHS compliant. Specifications are guaranteed over an industrial temperature range of -40°C to +85°C.
