Yes. Our partner, Xeltek has developed pre-programming systems for Everspin MRAM. See their site at http://www.xeltek.com/superpro-supports-mram-technology.

PACKAGE, ANNEAL, PLATING Are the Everspin parts Annealed after the lead frame is plated?

Yes. 1 hour anneal @ 150C after lead frame tin plating is standard process for our assemblers.

ECCN, EAR99, EXPORT CONTROL CLASSIFICATION NUMBER What is the Everspin Export Control Classification Number (ECCN)?

The Everspin Export Control Classification Number (ECCN) is EAR99.

CURIE TEMP What is the value of the Curie Temperature Point for Everspin MRAM products?

The Curie temperature for thin films of NiFe that are used in Toggle MRAM are well above 300C. We have verified no loss of data in Everspin Toggle MRAM that has been heated to 250C for several hours.

BOARD ASSEMBLY Are there any special handling requirements for board assembly using MRAM?

There are no special handling requirements for assembly of MRAM.

HANDLING REQUIREMENTS Are there any special handling requirements for shipping and receiving of MRAM?

There are no special handling requirements for shipping or receiving MRAM.

SYSTEM DESIGN TECHNIQUE FOR MRAM What are some system level design techniques that I could implement to reduce the risk of exposure to levels of external magnetic fields that may affect MRAM? Can I place an MRAM near motors or transformers?

Everspin MRAM has an absolute maximum magnetic field specification comparable to a Hard Disk drive. Everspin MRAM can be placed near motors or transformers as long as the magnetic field emanating from these components does not exceed the absolute maximum magnetic field specification at the location of the MRAM.

PART MARKING, DATE CODE Everspin has used 2 types of the marking in the past. Is there any chance to have "FATWLYYWW" type of marking from now on?

We are using the alternative format for all products now with the exception of the 4Mb x8,x16 and 1Mb x16 BGA. There is no plan to change back to the previous marking format.

MOISTURE SENSITIVITY What is the moisture sensitivity level of an MRAM part?

MSL-3 is the standard for all Everspin MRAM products. Some device/package combinations may be rated for less time out of the bag when in the early stages of their release and full MSL-3 qualification has not completed. Please check the device data sheet or contact Everspin to confirm the MSL level for a specific device.

LEADFRAME MATERIAL What is the leadframe material?

Cu Alloy 194. For more details request our Materials Composition Declaration document

ESD What are your standard ESD testing requirements?

Our standard ESD requirements are: Human Body Model: 2kV, Charged Device Model: 500V, Machine: not usually tested.
