A54SX16A-2FGG144

Overview

The A54SX16A-2FGG144 is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules within a 144-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 111 user-programmable I/O pins and features a maximum internal clock frequency of 350 MHz with system performance reaching 250 MHz. It operates at 2.5 V, 3.3 V, or 5 V with mixed-voltage support and includes dedicated flip-flops for sequential logic.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements
• Features nonvolatile single-chip architecture that prevents reverse engineering and design theft via FuseLock technology
• Provides deterministic timing through unique local routing resources including DirectConnect and FastConnect

Applications

• High-performance digital signal processing requiring fast counters and state machines
• PCI-compliant interface designs supporting 66 MHz PCI standards
• Secure embedded applications utilizing nonvolatile antifuse configuration

Procurement Notes

Verify the specific speed grade suffix '2' indicates approximately 25% faster performance than standard speed. Confirm the 'FG' package designation corresponds to the 1.0 mm Fine Pitch Ball Grid Array. Ensure the temperature grade matches the required operational environment as defined in the ordering matrix.

Selection Notes

Select this component when 24,000 system gates are sufficient for the target logic density. The -2 speed grade is appropriate for designs requiring higher throughput than standard grades. Verify that the FBGA-144 footprint aligns with the PCB layout constraints and that the pin count accommodates the necessary I/O interfaces.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers various capacity options ranging from 8,000 to 108,000 system gates. The A54SX16A variant specifically targets mid-range complexity applications requiring high performance and security.

Replacement Considerations

Direct replacements include other speed grades within the same package such as A54SX16A-1FGG144 or A54SX16A-FGG144. Cross-family migration to Microchip RT or PolarFire series may require architectural redesign due to differences in memory technology and routing structures.
