FM25C160 –

16Kb FRAM Serial Memory

Features

16K bit Ferroelectric Nonvolatile RAM

Very Fast Serial Peripheral Interface - SPI

Description

The FM25C160 is a 16-kilobit nonvolatile memory

employing an advanced ferroelectric process. A

ferroelectric random access memory or FRAM is

nonvolatile but operates in other respects as a RAM.

It provides reliable data retention for years while

eliminating the complexities, overhead, and system

level reliability problems caused by EEPROM and

other nonvolatile memories.

Unlike serial EEPROMs, the FM25C160 performs

write operations at bus speed. No write delays are

incurred. Data is written to the memory array

immediately after it has been successfully transferred

to the device. The next bus cycle may commence

immediately.

substantial write endurance compared with other

nonvolatile memories. The FM25C160 is capable of

supporting up to 10

than most systems will require from a serial memory.

These capabilities make the FM25C160 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 automotive controls where the long write

time of EEPROM can cause data loss.

The FM25C160 provides substantial benefits to users

replacement. The FM25C160 uses the high-speed SPI

bus, which enhances the high-speed write capability

of FRAM technology. The specifications are

guaranteed over an automotive temperature range of

-40°C to +125°C.

This product conforms to specifications per the terms of the Ramtron

standard warranty. The product has completed Ramtron’s internal

qualification testing and has reached production status.
