Spartan-3A FPGA
Mainstream Platform with added DSP and BRAM Capabilities
The Spartan®-3A platform is the ideal solution for low cost connectivity and DSP algorithmic and co-processing applications. Its support for a wide range of popular and emerging I/O standards, coupled with an extensive array of pre-engineered intellectual property (IP) solutions make it an ideal choice for bridging, differential signaling and memory interfacing applications. The largest devices offer increased DSP and BRAM capabilities for up to 30 GMAC/s and up to 2,200 Mbps memory bandwidth.
