A54SX16A-2PQ208

Overview

The A54SX16A-2PQ208 is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 combinatorial logic blocks (CLBs). The device supports up to 175 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. Operating at a standard supply voltage of 2.5 V with a range of 2.25 V to 2.75 V, it achieves a maximum system performance frequency of 250 MHz and an internal clock speed of 350 MHz. The -2 speed grade indicates approximately 25% faster performance than the standard grade.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/O standards including PCI, TTL, LVTTL, and LVCMOS2.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing and high-speed interconnect.
• Provides IEEE 1149.1 Boundary-Scan Testing capabilities with flexible or dedicated JTAG pin configurations.

Applications

• High-performance digital signal processing requiring fast counters and state machines
• PCI bus interface designs compliant with 66 MHz specifications
• Secure embedded control systems utilizing antifuse nonvolatile architecture

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific ordering suffix matches the required speed grade (-2) and temperature range (Commercial). Check for RoHS compliance status if lead-free packaging is mandated for the assembly process.

Selection Notes

Select this model when 24,000 system gates and 175 I/Os are sufficient for the design. The -2 speed grade is appropriate for applications requiring higher throughput than the standard grade offers. Ensure the PQFP208 package fits the PCB footprint constraints and thermal management requirements.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes metal-to-metal programmable antifuse technology. Unlike volatile FPGAs, these devices retain configuration data without external memory. The A54SX16A variant sits between the smaller A54SX08A and larger A54SX32A in terms of logic capacity and I/O availability.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology for current equivalent recommendations or migration paths from discontinued antifuse families.
