Two-wire Serial Interface Memory Features High Data Retention

Mon, 08/03/2009 - 9:13am
Ramtron’s FM24CL32 is a serial nonvolatile RAM that offers high-speed read/write performance, low voltage operation, and impressive data retention. The FM24CL32 features 32-Kilobit (Kb) nonvolatile memory, 2.7- to 3.6-V operation in an 8-pin SOIC package that uses two-wire (I2C) protocol. The FM24CL32 features fast access, NoDelay™ writes, virtually unlimited read/write cycles (1E14), and low power consumption. The device is a direct hardware replacement for serial EEPROM memory used in industrial controls, metering, medical, military, gaming, and computing applications, among others. Demanding industrial controls can benefit from the FM24CL32 where the long write time of EEPROM devices can cause data loss. In addition, the device provides reliable data retention for 45 years when operated at +75°C, a necessary retention time for the utility metering industry. The FM24CL32 is a serial ferroelectric random access memory organized as a 4,096 x 8-bit memory array and is accessed using an industry standard two-wire (I2C) communication interface.
