AN221E04 Datasheet – Dynamically Reconfigurable FPAA With Enhanced I/O PRODUCT AND ARCHITECTURE OVERVIEW The AN221E04 device consists of a 2x2 matrix of fully Configurable Analog Blocks (CABs), surrounded by a fabric of programmable interconnect resources. Configuration data is stored in a n on-chip SRAM configuration memory. Compared with the first-generation FPAAs, the Ana digmvortex architecture provides a significantly improved signal-to-noise ratio as w ell as higher bandwidth. These devices also ac commodate nonlinear functions such as sensor response line arization and arb itrary waveform synthesis. The AN221E04 device features an adva nced input/output structure that allows the FPAA to be programmed w ith up to six outputs – or triple the number provided by the ANx20E04 devices. The AN221E04 devices have four confi gurable I/O cells and two dedicated output cells. For I/O-intensive applications, this means a single F PAA can now be used to process multiple channels of analog signals where two or more such devices were previously needed. In addition, the AN221E04 devices allow designers to implement an integrated 8-bit analog-to-digital converter on the FP AA, eliminating the potential need for an external converter. Using this new device, de signers can route the digital output of the A/D converter off-chip using one of the dedicated output cells.
