Material Change for 16Mb (x8) TSOP-44p Package from OSE
Everspin is changing the die thickness from 3 mil to 4 mil for the 16Mb (x8) TSOP-44p Package from OSE. Additionally, the BLT1 and BLT3 material are changing from DAF to Epoxy, and the wire material is changing from 4N to 2N.
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.
PCN02784 Mold Compound Change for 44pin TSOP2 for ASE-KH
To improve flexibility in manufacturing Everspin has qualified the 44 pin TSOP2 package from ASE-KH (Kaohsiung) with a new mold compound, G631H. This mold compound is already in use at other assembly sites.
PCN02542 Add TICP as a qualified source of the 16Mb X8 in the TSOP2 package
To increase production capacity and improve flexibility in manufacturing Everspin has qualified TICP as an additional assembly location for the 16Mb (x8) MRAM.
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.
