Austin, Tex.—Freescale Semiconductor has expanded its magnetoresistive random access memory (MRAM) family with a 3-volt, 4-Mbit extended temperature range (-40 to +105C) non-volatile RAM (nvRAM).

This device enables entry into more rugged application environments, such as industrial, military and aerospace and automotive designs.

Freescale also has broadened its commercial MRAM line with a 1-Mbit device, offering system designers a density option that addresses the sweet spot of the mainstream embedded market. In addition, Freescale plans to expand its MRAM product family to include a total of nine commercial, industrial and extended temperature products during the third quarter of 2007.

MRAM uses magnetic materials combined with conventional silicon circuitry to deliver the speed of SRAM with the non-volatility of flash in a single, unlimited-endurance device. MRAM devices can be used in cache buffers, configuration storage memories, and other commercial applications that require speed, endurance and non-volatility. Freescale's latest extended temperature range option enables MRAM to be used in industrial and automotive applications in which semiconductor products must be qualified to withstand harsh operating environments and extreme temperature ranges.

1-Mbit MR0A16A
The MR0A16A is a 1-Mbit commercial temperature range (0 to 70°C), 3.3 volt asynchronous memory organized as 64K words by 16 bits, featuring 35 nanosecond read and write cycle times. The device's industry-standard SRAM pin-out allows memory expansion from 1-Mbit to 4-Mbit in a common footprint. The device is housed in a 400-mil TSOP type-II RoHS-compliant package and is appropriate for a variety of commercial applications, such as networking, security, data storage, gaming and printers.

4-Mbit MR2A16AV
The MR2A16AV is a 4-Mbit extended temperature range (-40 to 105°C), 3.3 volt asynchronous memory organized as 256K words by 16 bits, featuring 35 nanosecond read and write cycle times. Its industry-standard SRAM pin-out makes it compatible with SRAM and other nvRAM products. The device is housed in a 400-mil TSOP type-II RoHS-compliant package. It offers a robust NVM solution for demanding environments found in industrial automation, transportation, military and avionics applications.

Pricing: The suggested resale price for the MR2A16AV is $24.99 in 10,000-unit quantities, and the suggested resale price for the MR0A16A is $9.99 in 10,000-unit quantities. The 4-Mbit commercial temperature MRAM device (MR2A16A) is in volume production.
Availability: The 4-Mbit extended temperature MRAM (MR2A16AV) and the 1-Mbit commercial MRAM (MR0A16A) are sampling now. The 4-Mbit commercial temperature MRAM device (MR2A16A) is available at a suggested resale price of $14.99 in 10,000-unit quantities.
