Rochester Electronics has reintroduced a range of gate array semiconductors, suitable for advanced commercial, industrial, military and aerospace applications.

The Q20000 range from Applied Micro Circuits Corporation (AMCC) includes five technology nodes and some 500 designs.

The production of these components, which is completely authorised by AMCC, was accomplished through a combination of semiconductor replication and continuing manufacture.

Rochester has already recreated and manufactured the largest and most complicated device in the AMCC Q20000 series: a 0.6-micron bipolar emitter-coupled-logic (ECL)/transistor-transistor-logic (TTL) gate array device called the Q20M100.

The Q20000 range is comprised of nine products ranging in density from 450 to 18,777 equivalent gates, including structured arrays with 1.25GHz phase-locked loops (PLLs).

With the recreation of the largest and most complicated device in the range, the recreation of the rest of the Q20000 range is enabled.

For many equipment manufacturers who use this part, availability from Rochester has eliminated the need for system redesigns, saving them money in related redesign and qualification costs.

Rochester is also authorised to recreate and manufacture the AMCC Q14000 series BiCMOS logic arrays, the Q5000 series ECL/TTL logic arrays, the Q1500 series logic arrays and the Q700 series logic arrays.

Paul Gerrish, co-president at Rochester Electronics, said: ‘With full permission from AMCC, Rochester is now the contractually licensed continuing source of AMCC gate array devices.

‘Semiconductor recreation and continuing manufacturing is a cost-effective and time-saving alternative to system redesign when critical semiconductors are no longer available from authorised sources.

‘Rochester engineers use complex reverse-engineering techniques to recreate the device and provide a replacement that matches the original semiconductor’s physical features, layer by layer and pin for pin, and is guaranteed to perform exactly as the AMCC original,’ he added.

AMCC provided its gate array product IP and design archive databases to Rochester, enabling the company to produce a continuing supply of authorised devices through its Semiconductor Replication Process (SRP).

Rochester’s SRP combines archive identification, the tear-down of sample product, process match, source-to-target comparison, detailed Spice analysis and testing to the original manufacturer’s specifications and beyond, to exactly match the form, fit and function of the AMCC original gate array devices.
