Low Power, High Performance, High Reliability
ARORA ®

Arora® Family is designed to offer the best-in-class performance cost ratio FPGA. With abundant logic, high-performance DSP resources and high speed I/O, the family is optimized for co-processing to offload the application processor on intensive computation tasks. The Arora® family is also the first FPGA with embedded pSRAM in the industry, which gives customers more usable device I/O.
