Why Flash-Based FPGAs?

Unlike traditional SRAM-based FPGAs that require external configuration memory (and are vulnerable to bitstream attacks during boot), the A3P400 uses flash technology, offering:

✅ Instant-on Capability

• Powers up immediately with its configuration already in place

✅ Enhanced Security

• AES-based bitstream protection

• FlashLock for design anti-cloning and tamper resistance

✅ Lower Power Consumption

• No configuration current surges

• Lower static power than SRAM-based counterparts

✅ Single-Chip Simplicity

• No need for external boot memory, reducing BOM cost and board complexity
