CAMPBELL, Calif. -- Anadigm Inc., a fabless chip vendor with an engineering base in Crewe, England, has introduced its second field programmable analog array (FPAA), the AN220E04, plus supporting design software.
Campbell, California-headquartered Anadigm claims that the switched-capacitor based AN220E04 is the first FPAA that can be dynamically reconfigured to allow real-time control of analog functions by microprocessors or other circuitry within a system.
Thus the new part complements Anadigm's first part, the AN10E40, introduced when the company was called Anadyme Microelectronics Ltd. and which is almost identical to Pilkington Mictoelectronics' DPAD3, described on now defunct Pilkington Microelectronics' web site in 1995, and a part Motorola implemented in 1-micron technology in 1997 (see July 31, 2000 story ).
Pilkigton Microelectronics was the original source of Anadigm's technology which was formed as a buyout of the intellectual property from Motorola in 2000.
Compared with Anadigm's first-generation FPAAs, the AN220E04 architecture provides improved signal-to-noise ratio as well as higher bandwidth, the company said. A successive approximation register-based A/D converter can be combined with an on-board look-up table to provide advanced analog functions including sensor response linearization, arbitrary waveform synthesis, signal-dependent functions, analog multiplication, and signal companding.
"Our first-generation FPAAs created an entirely new paradigm for analog design by allowing even non-specialists to design and implement complex analog circuits in a fraction of the time required by designers using discrete components or analog ASICs," said Mike Kay, Anadigm president and chief executive officer, in a statement.
Kay continued: "With the dynamic reconfigurability introduced by the Anadigmvortex family, the comparative benefits of FPAAs become even more dramatic, not only for the process of analog design but as a redefinition of the way analog will work and be controlled in the software-centric systems of today and tomorrow."
Packaged in the 44-pin QFP, samples and production quantities of the AN220E04 are available with pricing in 10,000-piece quantities for U.S. delivery starts at $15.00, the company said.
