*** NOT FOR NEW DESIGN's ***
The AN221E04 and all 5volt (Vortex Family) FPAA's are now at the end of life.
For new designs please use the AN231E04 FPAA (dpASP).

The AN221E04 Dynamically Reconfigurable Field Programmable Analog Array With Rich I/O Cell Design
The AN221E04 was inspired by feedback received from our customers. This new version, has more outputs to implement analog designs on a single integrated platform. It also has analog to digital conversion after signal conditioning functionality integrated onto the same chip.

The new AN221E04 features an advanced input/output structure that lets you program the dpASP 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. For I/O-intensive applications, this means you can now use a single dpASP to process multiple channels of analog signals where two or more such devices were previously needed.

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

With dynamic reconfigurability, you can program the AN221E04 to implement multiple analog functions and/or to adapt on-the-fly to maintain precision operation despite system degradation and aging. With analog functions defined by software, the analog subsystem can be controlled using C-code automatically generated by AnadigmDesigner®2.
