Overview
The MityDSP-L138F-A7 offers a transition path for customers dealing with SPARTAN-6 replacement / obsolescence, and is a drop-in replacement for the MityDSP-L138F.
The MityDSP-L138F-A7 is a highly configurable, small form-factor processor card that features a Texas Instruments OMAP-L138 456 MHz (max) Applications Processor (OMAP) tightly integrated with the Xilinx Artix-7 Field Programmable Gate Array (FPGA), FLASH (NAND, and NOR) and mDDR2 RAM memory subsystems. The design of the MityDSP-L138F-A7 allows end users the capability to develop programs/logic images for both the OMAP and the FGPA.
