Software puts standard filters on analogue arrays
Anadigm has added filter synthesis to its field-programmable analogue array (FPAA) configuration software.
As a replacement for discrete component or ASIC solutions, dynamically reconfigurable FPAAs greatly simplify the analogue design process while allowing on-the-fly, real-time control of analogue functions by the microprocessor in an embedded system.
The new AN221E04 features an advanced input/output structure that allowing the FPAA to be programmed with up to six outputs - or triple the number provided by the AN220E04.
The device has four configurable I/O cells and two dedicated output cells.

Software supprts reconfigurable analogue arrays
A breakthrough analogue EDA tool enables the design and implementation of dynamically reconfigurable analogue circuits within a matter of minutes.
For I/O-intensive applications, this means a single FPAA can now be used to process multiple channels of analogue signals where two or more such devices were previously needed.
In addition, the AN221E04 allows designers to implement an integrated 8bit analogue-to-digital convertor on the FPAA, eliminating the potential need for an external convertor.
Using this new device, designers can route the digital output of the A/D convertor off-chip using one of the dedicated output cells.
"The AN221E04 was inspired by feedback we've received from customers who needed more outputs to implement their analogue designs on a single integrated platform", said Michael Sera, Vice President of Marketing at Anadigm.
"Many customers need analogue to digital conversion after signal conditioning, and now that functionality can be integrated on the same chip".
Anadigm's proprietary FPAA technology brings the industry an analogue equivalent to the FPGA, allowing complex analogue signal conditioning and processing functions to be integrated within an off-the-shelf, pretested device.
Designers will program the AN221E04 using AnadigmDesigner2 EDA software, the latest in a family of design tools from Anadigm that allow designers to construct complex analogue functions using configurable analogue modules (CAMs) as building blocks.
With an easy-to-use drag-and-drop interface, the design process can be measured in minutes, allowing complete analogue systems to be built rapidly, simulated immediately, and then downloaded to the FPAA chip for testing and validation.
With dynamic reconfigurability, the functionality of the AN221E04 can be reconfigured in-system by the designer or on the fly by a microprocessor.
A single AN221E04 can thus be programmed to implement multiple analogue functions and/or to adapt on-the-fly to maintain precision operation despite system degradation and aging.
With analogue functions defined by software, control is easily implemented using C-code automatically generated by AnadigmDesigner2.
In addition to the AN221E04, Anadigm offers the statically reconfigurable AN121E04, which shares the same input/output structure while requiring a reset before loading a new configuration bitstream.
Packaged in the 44-pin QFP, samples and production quantities of both devices are available now.
Pricing in 10,000-piece quantities for US delivery starts at $16 for the AN221E04 and $8.95 for the AN121E04.
A multimedia demonstration of the AnadigmDesigner2 EDA tool can be viewed at the Anadigm website.
A complete evaluation kit with a development board, entry-level software and updated documentation is now available for $499.
