Emerson Network Power announced a new single-board computer called the MVME2500. It has a 800Mhz or 1.2Ghz Freescale QorIQ™ P2010 (or P2020) processor, 1GB or 2GB of DDR3-800Mhz memory and 512KB of MRAM (made by Everspin, no doubt).

The MVME2500 also includes 3 Gigabit ethernet interfaces, 5 serial ports, 1 USB 2.0 port, one PCM/XMC port and a H/D mounting kit (optional).

Aeroflex Colorado Springs has licensed MRAM technology from Everspin for the development of HiRel nonvolatile memory solutions for aerospace and defense applications. Aeroflex will develop 4Mb and 16Mb MRAM monolithic solutions with guaranteed total ionizing dose and single event effect hardness. Aeroflex envisions HiRel MRAM solutions being used with microprocessors, DSP engines, storage systems, instruments, and reconfigurable FPGAs that require guaranteed total ionizing dose and single event hardness.

Aeroflex’s MRAM roadmap includes a family of -55oC to +125oC, QML products offered in ceramic packages per a Standard Microcircuit Drawing (SMD). As a replacement for 3.3 volt asynchronous SRAM, Aeroflex products will be 8-bit parallel I/O solutions in densities of 4M, 16M, and 64Mbit. All products are designed to operate from a single 3.3 volt supply. With data retention after each write of 20 years and infinite read/write endurance, Aeroflex MRAM products are ideal for working memory applications that require high rates of data overwrites.

Everspin Technologies has named Phillip LoPresti its president and CEO.

“I am looking forward to building on MRAM’s success across multiple markets and leading Everspin through the next stage of our technology development,” said Phillip LoPresti. “Our strong product portfolio and proven track record positions us to expand market share as more customers recognize the value of our products. Everspin is focused on leveraging its MRAM expertise and resources to accelerate the introduction of new products in development based on our next-generation, high density Spin Torque MRAM technology.”

Everspin has announced a new MRAM chip (MR4A16B) with 16-megabit (Mb) density. Samples are available now, and mass-production will begin in July 2010. There are two options for the chips: commercial chips and industrial chips (that have a larger temperature range: -40°C to +85°C). Everspin also promises to continue and deliver MRAM at increasingly higher densities.

This is the first time since the MRAM chips were introduced by Freescale in 2006 that they announce higher-density chips.

Everspin has a new prodcut - a dual-supply MRAM designed to directly interface with next-generation logic products requiring low voltage I/Os. RAID systems using advanced logic controllers operating with 1.8 volt I/Os will be able to seamlessly interface with this MRAM.

The MR0D08B dual supply MRAM product operates from a VDD main supply voltage of 3.0 to 3.6V and allows a wide, user defined I/O operating range by setting the VDDQ I/O supply voltage level from 1.65 to 3.6V. Typical applications using 1.8V logic controllers would set VDDQ at 1.8V to support direct connections between the controller and the MRAM, eliminating any requirements for level shifters. The devices are housed in a small footprint 8mm x 8mm, 48-BGA package with 0.75mm ball centers.

Everspin is introducing a new family of MRAM products, with a Serial Peripheral Interface (SPI) bus. The new family is called MR24H and includes 256Kb, 512Kb and 1Mb products. These Everspin MRAM devices require no write delay, run at clock speeds as fast as 40 MHz and have unlimited endurance with more than 20 years data retention. 

The MR25H256 (256Kb), MR25H512 (512Kb) and MR25H10 (1Mb) serial MRAM products operate from  2.7 to 3.6 volts while offering low standby and operating currents as well as a 3 uA (typical) sleep mode to further improve the system power consumption. They are byte-organized internally, containing 32KB, 64KB and 128KB of data respectively. Industry-standard serial SPI command codes and timing enable easy connection to existing MCU and system designs. The devices are housed in low profile 8-pin RoHS-compliant DFN packages that are pin-out and footprint compatible with serial EEPROM, Flash and FeRAM products in comparable DFN or SOIC packages.

Everspin announced today that Airbus has decided to use their MRAM for the flight control computer on the A350 XWB aircraft.

Airbus will use 4Mb and 16Mb MRAM chips. The MRAM will replace both SRAM and Flash components.

Emerson Network Power says they will use Everspin's 4Mb MRAM in three of their newest high-performance single-board computers (the MVME7100 and MVME4100 VMEbus boards and CPC16200 CompactPCI board).

Emerson's boards are used in industrial, medical, military, aerospace and advanced telecom platforms. 

Everspin says that in secure applications, their MRAM is capable of holding both security keys and the security algorithms that can be updated frequently during operation without concern for memory wear-out like traditional Flash memory. In addition, MRAM can be erased in just milliseconds if a concern or compromising situation occurs, minimizing potential threats to security.

Everspin has shipped more than 100K 4Mbit MRAM chips to Siemens’ Industry Automation division. Siemens uses the MRAM in an industrial touch-screen application. They have reported zero field failures over the last two years.

Siemens uses Everspin MRAM to maintain software-programmable logic controller (SoftPLC) process data for its Simatic Multipanel MP 277 and MP 377 multi-panel human machine interface (HMI) products without battery backup.

Siemens started using the MRAM back in March 2008.

Everspin Technologies, the global leader in MRAM and integrated magnetic products, has greatly expanded its worldwide sales network in response to the growing interest in MRAM and the rapid increase in customer design activity incorporating its products.

“We have an expanding global base of customers in storage, industrial automation, communication, consumer, gaming and avionics markets,” said Saied Tehrani, chief operating officer for Everspin Technologies.
