The EM064LX HR and EM128LX HR devices are Everspin Technologies’ latest high-reliability additions to the PERSYST MRAM product range. For aerospace, defense, automotive, and high-end industrial applications, these new xSPI MRAM solutions offer the most robust mix of endurance, temperature performance, and data retention in the industry. They are designed for harsh working environments.
These latest improvements provide AEC-Q100 Grade 1 qualification for operation from -40°C to +125°C, extending Everspin’s leadership in non-volatile memory.
Every device has a 48-hour burn-in period and a 10-year data retention period at 125°C, guaranteeing consistent performance even under the most taxing circumstances.
Key Benefits of Everspin’s PERSYST EMxxLX High-Reliability MRAM:
- AEC-Q100 Grade 1 qualified, -40°C to +125°C operating range
- 10-year data retention at 125°C with unlimited read/write endurance for 10 years
- 48-hour burn-in for added reliability margin
- Industry-standard QSPI interface and packages for design flexibility
- Proven MRAM technology backed by independent testing and field validation
The EM064LX HR and EM128LX HR are designed for systems that cannot risk data loss or degradation. Their 64- and 128-megabit densities achieve 90 Mbytes/sec read and write bandwidth, sustained for more than ten years.
The Berkeley Accelerator Space Effects (BASE) Facility at Lawrence Berkeley National Laboratory conducted independent radiation testing of the EM064LX device as part of a NASA Jet Propulsion Laboratory effort.
The device’s great reliability was confirmed by the tests, which revealed no single-event latch-up (SEL) events up to a LET of 61 MeV-cm²/mg at room temperature. Both the devices support consistent performance because they have the same design architecture and high-reliability specifications.
The new solutions offer high bandwidth for data-intensive applications while preserving the predictable performance MRAM is renowned for thanks to a Quad Serial Peripheral Interface (QSPI) that supports 133 MHz single transfer rate and 90 MHz dual transfer rate operation.
Because of these features, the new devices family of devices is perfect for systems that need secure, persistent memory where dependability and bandwidth are equally crucial.
Leadership Comments
“Our customers design systems that must perform without compromise in the harshest environments,” says Sanjeev Aggarwal, President and CEO of Everspin Technologies. “EM064LX and EM128LX family of products offer the most reliable and durable non-volatile memory where density and total bandwidth are key requirements. These solutions demonstrate Everspin’s ongoing commitment to supporting mission-critical designs that rely on memory performance and reliability under extreme conditions.”
