SX-A FPGAs

SX-A Family of Antifuse FPGAs

The SX-A family of FPGAs offers a cost-effective, single-chip solution for low-power, high-performance designs. SX-A devices can be used to generate system-wide savings by integrating multiple functions into a single-chip solution. Providing a combination of performance, security and low power, SX-A FPGAs decrease the premium for performance while providing a solution that is highly resistant to reverse engineering.

Key Benefits

350 MHz internal performance
2.5V, 3.3V and 5.0V mixed-voltage support
100% resource utilization with 100% pin locking
66 MHz, 64-bit 3.3V/5.0V PCI performance (supporting target, master and master/target)
Availability in military and automotive temperature grades
