Priced at $4.95 in 1,000-piece quantities, the new AN221E02 makes programmable analog an affordable option for simple analog filtering, sensor conditioning and basic PID control applications. Using half the Configurable Analog Block (CAB) resources of previous Anadigmvortex FPAAs, the AN221E02 serves in a wide range of industrial, audio, automotive, medical, communications, automatic test equipment, and instrumentation systems, replacing discretes or ASICs with a programmable, pre-tested, single-chip device.
Statically and dynamically reconfigurable, the AN221E02 allows on-the-fly, real-time control of analog functions by the microprocessor in an embedded system. Using dynamic reconfiguration, designers can manipulate the loop response of their design, change filter characteristics in response to shifting environmental conditions, or adjust coefficients without interrupting the operation of the FPAA.
�As the new entry-level product for our second-generation Anadigmvortex family, the AN221E02 gives designers a compelling opportunity to use programmable analog as a price-competitive alternative to discretes and ASICs, even for simple analog circuit implementations� said Brian Hodges, vice president of worldwide marketing at Anadigm�.�
The AN221E02 features two configurable I/O cells that can serve as inputs or outputs, plus two dedicated output cells. Its fully differential architecture provides a signal-to-noise range of 80 dB for broadband and 100 dB for narrowband (audio) applications. Typical bandwidth ranges from DC to 2 MHz depending on function.
Designers will program the AN221E02 using AnadigmDesigner�2, an EDA tool that constructs complex analog circuits for applications such as signal conditioning, closed loop control, and data acquisition using Configurable Analog Modules (CAMs) as building blocks. Adjustments to the circuit can be made graphically, or in C-code, which AnadigmDesigner�2 generates automatically. With an easy-to-use drag-and-drop interface, the design process can be measured in minutes, allowing complete analog systems to be built rapidly, simulated immediately, and then downloaded to the FPAA chip for testing, validation, and a direct move to manufacturing. The free trial version of AnadigmDesigner� provides users full access to all the software�s features, including the ability to construct circuits that can be reconfigured on the fly by a system microprocessor.
�Analog functions and analog design are two of the key areas for future device development, as well as a technology that has been ignored, for the most part, until recent years,� said Jerry Worchel, Senior Analyst at In-Stat/MDR. �In light of current economic conditions, coupled with increasing demand for improved and more flexible analog design capability, as well as reconfigurability, designers should not pass up the opportunity for a free trial � it may prove more valuable than one would think. One can consider the Anadigm approach as the analog world�s equivalent to the digital world�s FPGA.�
A multimedia demonstration of AnadigmDesigner�2 v2.3 can be viewed at the Anadigm� Web site at http://www.anadigm.com. A free trial copy of AnadigmDesigner�2 v2.3 is available for download at http://www.anadigm.com/Down_05_a.asp. A complete evaluation kit with a development board, entry-level software, and updated documentation is now available at a promotional price of $199.

About Anadigm�
Anadigm� brings platform-based design to the analog world with pre-qualified software and hardware components that allow complex analog circuits to be implemented in an analog equivalent to the FPGA. Designed to implement signal conditioning, filtering, data acquisition, closed-loop control, and other analog functions in a wide range of embedded systems, Anadigm� FPAAs are first programmable analog ICs that can adapt on the fly to perform multiple functions, adjust to different environmental conditions, or compensate for equipment aging. Founded in January 2000 as a venture-backed technology spin-off from Motorola, Anadigm� maintains U.S. headquarters in Campbell, Calif., and European headquarters in Crewe, U.K. For further information, visit Anadigm� on the Web at http://www.anadigm.com.
