512Kx8 Plastic Monolithic SRAM CMOS
WEDC's ruggedized plastic 512Kx8 SRAM that allows
the user to capitalize on the cost advantage of using a
plastic component while not sacrificing all of the reliability
available in a full military device.
FEATURES
■
512Kx8 bit CMOS Static
■
Random Access Memory
Extended temperature testing is performed with the test
patterns developed for use on WEDC’s fully compliant
512Kx8 SRAMs. WEDC fully characterizes devices
to determine the proper test patterns for testing at
temperature extremes. This is critical because the
operating characteristics of device change when it is
operated beyond the commercial guarantee a device that
operates reliably in the field at temperature extremes.
Users of WEDC’s ruggedized plastic benefit from WEDC’s
extensive experience in characterizing SRAMs for use in
military systems.
• Access Times of 17, 20, 25ns
• Data Retention Function (LPA version)
• Extended Temperature Testing
• Data Retention Functionality Testing

Single +5V (±10%) Supply Operation
RoHS compliant
WEDC ensures Low Power devices will retain data in Data
Retention mode by characterizing the devices to determine
the appropriate test conditions. This is crucial for systems
operating at -40°C or below and using dense memories
such as 512Kx8s.
WEDC’s ruggedized plastic SOJ is footprint compatible
with WEDC’s full military ceramic 36 pin SOJ.
