Spartan-3A FPGA Family: Functional Description
Related Product Families
The Spartan-3AN nonvolatile FPGA family is architecturally
identical to the Spartan-3A FPGA family, except that it has
in-system flash memory and is offered in select
pin-compatible package options.

The compatible Spartan-3A DSP FPGA family replaces the
18-bit multiplier with the DSP48A block, while also
increasing the block RAM capability and quantity. The two
members of the Spartan-3A DSP FPGA family extend the
Spartan-3A density range up to 37,440 and 53,712 logic
cells.
