I have mentioned it before on our Road to embedded world, I love staying close to home. On a short trip, we visit Everspin Technologies where we are treated to view its EM064LX, a high performing persistent memory capable of reading 400 Megabytes per second connected to eXpanded SPI interface, and byte level addressability The EM064LX has over 4X the capacity of earlier serial non-volatile memories, and is a long-term solution with the user not having to worry about wear. It will retain its data for >100 years at 70 degrees Celsius. Everspin will be presenting the future of unified memory at embedded world 2023.
While visiting embedded world make a stop by booth 3A-201 where Everspin will demonstrate how its platforms are replacing technologies such as SRAM, nvSRAM, and NOR memories in application areas such as Industrial IoT, Process Automation and Control, FPGA Configuration, Aero/Avionics, Medical, and Gaming.
The highlights tthat you will see demonstrated at embedded world include:
- Expanded SPI bus interface supporting
- Octal, Quad, Dual and Single SPI protocol
- Up to 200MHz single and double transfer rate (STR/DTR) for Octal SPI
- Up to 133MHz, SPI, DSPI, QSPI
- Data endurance: Unlimited read, write and erase operations for supported life of product
- Data retention 10 Years minimum across temperature
- JEDEC compliant: JESD251, JESD251-1
- Byte level writes and reads with no erase required as persistent memory
- Data integrity: No external ECC required.
- Low Power Modes:
- Standby < 350μA (64Mb)
