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.
PCN02693A Add OSE as a qualified assembly subcontractor
To increase production capacity and improve flexibility in manufacturing Everspin has qualified an additional subcontractor, OSE, for assembly of the TSOP- 44 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.
ASE QUALIFIED AS ADDITIONAL TSOP ASSEMBLY SITE
Everspin has qualified nine additional products for TSOP assembly at assembly subcontractor ASE. PCN date August 19, 2011, effective November 18, 2011

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.
