Anadigm’s FPAA has I/O cell design for multichannel signal processing

Campbell, CA151; Anadigm Inc. released March 31 its dynamically reconfigurable Field Programmable Analog Array (FPAA) with a versatile input/output cell design. As the latest offering of the second-generation Anadigmvortex family, AN221E04 FPAA will be used by designers to implement signal conditioning filtering, data acquisition, closed-loop control, and other analog applications in many industrial, automotive, medical, communications, automatic test equipment and instrumentation systems.

As replacements for discrete components or ASIC solutions, dynamically reconfigurable FPAAs simplify analog design processes, while allowing on-the-fly, real-time control of analog functions by the microprocessor in an embedded system.

AN221E04 features an advanced I/O structure that allows the FPAA to be programmed with up to six outputs, which is triple the number provided by the AN220E04. The new device has four configurable I/O cells and two dedicated output cells. For I/O-intensive applications, this means one FPAA can now be used to process multiple channels of analog signals, instead of the two or more devices previously needed.

AN221E04 also allows designers to implement an integrated 8-bit analog-to-digital converter on the FPAA, eliminating the potential need for an external converter. Using this new device, designers can route the digital output of the A/D converter off-chip using one of the dedicated output cells.

lity can be integrated on the same chip.’

Anadigm adds that its proprietary FPAA technology gives users an analog equivalent to the FPGA, allowing complex analog signal conditioning and processing functions to be integrated within an off-the-shelf, pre-tested device.

Designers will program AN221E04 using AnadigmDesigner2 EDA software, which allows designers to construct complex analog functions using configurable analog modules (CAMs) as building blocks. The software’s drag-and-drop interface allows analog systems to be built rapidly, simulated immediately, and then downloaded to the FPAA chip for testing and validation.

AN221E04’s functions can be reconfigured in-system by the designer or by a microprocessor. One AN221E04 can be programmed to implement multiple analog functions and/or adapt on the fly to maintain precision operation despite system degradation and aging. With analog functions defined by software, control is implemented using C-code automatically generated by AnadigmDesigner2.
