1 Mbit FRAM memory has industry-leading features

1 June 2005 DSP, Micros & Memory

The FM20L08 is Ramtron's highest-density FRAM memory to date and offers an unlimited number of read/write cycles.

The FM20L08 is a 1 Mbit (organised as a 128K x 8), 3 V, nonvolatile ferroelectric random access memory (FRAM) product in a 32-pin TSOP package. The product has been designed as a drop-in replacement for standard asynchronous static random access memories (SRAMs) and is targeted for systems that collect and store data where power levels can vary or power can be lost suddenly, such as set-top boxes, automotive telematics and industrial applications.

The FM20L08 provides fully compatible SRAM timing with address transition detection (ATD), which allows users to change addresses while leaving the chip enable active. It responds to each address just like SRAM, greatly simplifying the design engineer's task in using a nonvolatile RAM.

Ease of use was Ramtron's goal in the memory's design. In addition to acting as a standard SRAM, the product includes an internal voltage monitor to lock-out low voltage access and protect stored data. The monitor continuously checks the supply voltage and asserts an active-low signal to indicate that the memory is write-protected when VDD drops below a critical threshold. It also features software-controlled write protection.

The memory array is divided into eight uniform blocks, each of which can be individually write-protected under software control with no change to hardware or pin-out. It is offered in both industrial (-40 to +85°C) and commercial (0 to


+70°C) temperature ranges. Cycle time for the commercial part is 150 ns, while cycle time for the industrial version is 350 ns.
