512-Kilobit Serial F-RAM with high-speed read/write performance

Ramtron International Corporation launched the second serial device in a family of new F-RAM products. The device offers high-speed read/write performance, low voltage operation, and optional device features. The FM25V05 is a 512-kilobit (Kb), 2.0 to 3.6-volt, serial peripheral interface (SPI) nonvolatile RAM that features fast access, "NoDelay" writes, 1E14 read/write cycles, and low power consumption.

The FM25V05 is an ideal alternative to serial Flash and serial EEPROM memory in industrial control, metering, medical, automotive, military, gaming, and computing applications, among others. In addition to the 512Kb FM25V05, the 1-megabit FM25V10 is also available.

Some of the features include:

1. Unlike serial Flash memory or serial EEPROM, the FM25V05 performs write operations at bus speed without write delays.
2. Data can be written continuously up to 40 megabits per second.
3. Compared to serial Flash and serial EEPROM, the FM25V05 consumes less power.
4. Ideal for nonvolatile memory applications that require frequent or rapid writes or low power operation.
5. Applications range from high frequency data collection where the number of write cycles is critical, to industrial controls where the long write time of serial Flash or EEPROM devices is impractical due to potential data loss.
6. The FM25V05 has a read-only device ID and can be ordered with a unique serial number and/or system reset option.
7. The FM25V05 operates over the industrial temperature range of -40°C to +85°C.
8. It consumes only 3 milliamps while running at a 40MHz SPI clock rate, 90 micro-amps during standby, and 5 micro-amps during sleep mode.
9. It offers a typical active power consumption of 38 microamps per MHz, which is an order of magnitude lower current than similar serial Flash or EEPROM products.
10. It is Manufactured on the 130nm CMOS manufacturing process
