e2v Aerospace and Defense Completes Redesign of Bipolar PROM Family

Press release date: January 17, 2014

e2v aerospace and defense today announced that it has completed full qualification of a family of industry-standard Bipolar PROMs. These products have been fully re-engineered and manufactured on a Bipolar process and meet the original manufacturer specifications for military and aerospace applications. These devices serve as drop-in replacements for the original devices, manufactured by a variety of suppliers, including Philips/Signetics, Harris, MMI, Fairchild, National, and Raytheon.

The PROM family has four members, ranging in size from 2K (512 x 8) to 16K (2K x 8), and ranging in speed from 90ns to 125ns. These PROMs are field programmable OTP (One-Time Programmable) devices, offering on-chip address decoding without separate fusing pins, three-state outputs and full TTL-compatibility. Supported device types are shown in the cross reference.

These devices are available in a variety of ceramic package options: Leadless Chip Carriers (LCCs), Dual Inline Packages (DIPs) and Flatpacks (FPs); all manufactured in compliance with the latest revision of MIL-PRF-38535, making them ideally suited for defense applications. These devices are available to Standard Microcircuit Drawings and/or Military Slash Sheet Specifications.

““This product release demonstrates e2v’s design expertise and commitment as supplier of components and subsystems for aerospace systems applications,” said Mr. Robert Brevelle, President e2v a&d.  “We continue to support the warfighter by extending the lifetime of mission critical systems.”
