PCN02967 Moisture Sensitivity Level of the 16Mb MRAM in the 48-BGA Package Upgraded to MSL-3.pdf
The 16Mb MRAM in the 48-BGA is being upgraded from MSL-5 to MSL-3.
PCN02954 Moisture Sensitivity Level of the 16Mb MRAM in the 48-BGA Package Upgraded to MSL-5.pdf
The moisture sensitivity level for these products was previously stated as MSL-6 as of March 22, 2016 in PCN 02941. This PCN is to notify customers that the moisture sensitivity level is upgraded to MSL-5. This improvement is the result of package materials and process optimization in conjunction with Everspin assembly subcontractor UTAC Dongguan.

PCN02370 Everspin is adding ASE-Malaysia as a qualified assembly site
In order to increase capacity and improve supply flexibility, Everspin is adding ASE-Malaysia as a qualified assembly site for 16Mb MRAM products in the 48-BGA package.
PCN02756 Adding ASE Malaysia as a Qualfied Assembly Site on 16Mb BGA Product_final_C.pdf
Everspin is adding ASE-Malaysia as a qualified assembly site for 16Mb MRAM products in the 48-BGA package.
PCN1893 ALTERNATIVE FORMAT FOR TRACE CODES ON PACKAGE MARKING
Beginning December 30, 2011, Everspin may use an alternative Trace Code marking format interchangeably with the existing format. The existing format identifies fabrication site, assembly site, final test site and wafer lot, year and work week. The alternative format will identify the assembly site and wafer lot, year and work week. Affects all Everspin products and packages.

MRAM Improvements to Automotive Non-Volatile Memory Storage
Automotive powertrain modules use flash memory technology to retain critical control and diagnostic information during power off (keep-alive memory (KAM) and non-volatile memory (NVM)). Complex software must be designed to maximize the lifecycle of these devices because they have a limited number of write cycles. MRAM (Magneto resistive Random Access Memory) has the potential to eliminate this complexity and make the process of managing KAM and NVM easier and more robust. This paper demonstrates using off-board MRAM devices with a next generation of powertrain microprocessor. The prototype boards integrating the latest powertrain microcontroller, with the Everspin MRAM MRA16A (2 pcs of x16 bits) and MR2xH50 (@ a SCK 40MHz) chips were created. An investigation was performed evaluating the MRAM capabilities for storing and retrieving data during simulated key-off and key-on events.
