AN221D04-EVAL中文资料etc未分类制造商数据手册PDF规格书

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 an on-chip SRAM configuration memory. Compared with the first-generation FPAAs, the Anadigmvortex architecture provides a significantly improved signal-to-noise ratio as well as higher bandwidth. These devices also accommodate nonlinear functions such as sensor response linearization and arbitrary waveform synthesis.
