A54SX16A-FTQ100

Overview

The A54SX16A-FTQ100 is a 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 configurable logic blocks (CLBs). The device supports up to 350 MHz internal performance and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It features 81 user-programmable I/O pins in a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing and high-speed signal propagation.
• Compliant with IEEE Standard 1149.1 (JTAG) for boundary-scan testing and diagnostic verification.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Applications involving mixed-voltage I/O standards including 3.3V PCI and 5V TTL

Procurement Notes

Verify the specific speed grade associated with the 'F' suffix against current manufacturer documentation, as standard speed grades are typically designated by blank or numeric codes. Confirm RoHS compliance status and packaging details directly with Microchip Technology or authorized distributors, as ordering suffixes may indicate lead-free or specific environmental certifications.

Selection Notes

Select this device when 24,000 system gates and 1,452 CLBs are required within a 100-pin TQFP footprint. Ensure the design utilizes the SX-A architecture's unique antifuse programming capabilities and benefits from the nonvolatile nature of the fabric. Verify that the target application supports the 2.5V, 3.3V, or 5V I/O voltage levels supported by the SX-A family.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance applications. The SX-A series offers various gate counts ranging from 12,000 to 108,000 system gates across different device models like A54SX08A, A54SX32A, and A54SX72A.

Replacement Considerations
