Ramtron has released the industry's first 2-megabit (Mb) serial F-RAM memory in an 8-lead TDFN (5.0 x 6.0 mm) package.

Manufactured on an advanced 130 nanometer CMOS process, the FM25H20 is a high-density nonvolatile F-RAM memory that is designed to operate at low power. Featuring a high-speed serial peripheral interfac (SPI), the 3-volt, 2Mb serial F-RAM writes at maximum bus speed. It aims to reduce costs and board space in a range of advanced applications including meters and printers.

Ramtron is targeting the FM25H20 as a replacement for serial Flash in sophisticated electronic systems that require low power and minimal board space. These include portable medical devices such as hearing aids, which are essentially mini data processors with limited space and low power budgets.

The FM25H20 is organized as a 256K x 8 bit nonvolatile memory that reads and writes at bus speed up to 40MHz, with 10-year data retention, and low operating currents. A hardware and software write protection feature is also included on the FM25H20 to prevent inadvertent writes and data corruption.

The 2Mb serial F-RAM draws 10 milliamps for reads/writes, 25 microamps in standby, and 5 microamps in ultra-low-current sleep mode. Pin-compatible with equivalent serial Flash devices, the 2Mb F-RAM operates from 2.7 to 3.6 volts over the entire industrial temperature range (-40 degrees C to +85 degrees C).
