Servenger platform eases design with Anadigm FPAAs

Servenger LLC disclosed that they unveiled a hardware development platform that gives designers a running start working with field programmable analog arrays (FPAAs) from Anadigm Inc.

According to Servenger, the new Programmable Analog Module (PAM) products are predesigned circuit boards and accessories that allow users to quickly and easily design analog sensor interfaces, measurement circuits, voice band processing circuits, PID systems and a myriad of other analog functions that can be implemented in a software-controlled FPAA.

Completely compatible with the AnadigmDesigner2 drag-and-drop EDA tool, the PAM products provide power, control, clocking, input and output analog buffering, and serial communications to the host computer, allowing designers to use the PAM board straight out of the box as a free-standing evaluation module or as a board-level system component.

"With the PAM-5000R, we are giving designers the opportunity to work smarter with programmable analog, since we have done all the FPAA set-up work," stated Servenger President Steve Wetterling.

Wetterling added that their new product offers easy usage. "Take the module out of the box, plug in the included power adapter, and connect it to a PC. That is all the set-up that is required to get on the way to speeding up your design cycle and reducing time-to-market," he explained.

In advance over standard FPAA development kits, the PAM gives designers the ability to format and store the downloaded design configuration file into an on-board EEPROM for later standalone operation, making unnecessary the purchase of a separate programmer.

The PAM-5000R provides seven analog inputs and two outputs; an on-board Anadigm AN221E04 FPAA, EEPROM and power supply; an RS-232 interface; and accessories including an ac adapter, serial cable, mating connectors and Quick Start Guide. Board dimensions are 79-by-74mm.

The Anadigm FPAA

The AN221E04 FPAA provided on the PAM-5000R can be programmed and reprogrammed to perform an open-ended set of analog circuit functions. The AnadigmDesigner2 graphical design environment runs in Microsoft Windows and allows the designer to select from a large library of pre-tested analog functions and then place and connect them to create the desired circuit simply by dragging and dropping. Selecting the "Download" button compiles a configuration file and downloads it over the RS-232 serial port into the FPAA in the PAM.

Anadigm's FPAA is completely reconfigurable. To adjust a parameter or to make a major change, the designer simply downloads a new file. AnadigmDesigner2 handles all of the internal details of the FPAA configuration, and for system installations requiring a continuous stream of

configuration updates, it delivers C-code representations of the analog functions that can be added to system-level control code.

Priced at $369, the PAM-5000R is already available for purchase with discounted packages of 5 and 10 PAMs also available. An extensive Technical User Manual is provided on Servenger's website.
