A54SX32-1TQ144

Overview

The A54SX32-1TQ144 is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 360 user-programmable I/O pins and includes 1,980 dedicated flip-flops. It features three global clock networks and operates with internal performance up to 350 MHz. The component utilizes nonvolatile antifuse interconnects for permanent configuration.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V with hot-swap compliant I/Os
• Features deterministic timing through DirectConnect and FastConnect routing resources
• Includes IEEE 1149.1 compliant Boundary Scan Testing and FuseLock security technology

Applications

• 66 MHz PCI compliant designs
• CPLD and FPGA integration single-chip solutions
• High-performance state machines and fast counters
• Secure embedded systems requiring reverse engineering protection

Procurement Notes

Verify the specific speed grade suffix '1' indicates approximately 15% faster performance than standard speed. Confirm the temperature grade suffix 'I' corresponds to the industrial range of -40°C to +85°C. Ensure the TQFP package type matches the design footprint requirements. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this device when 48,000 system gates and 2,880 CLBs are required within a 144-pin Thin Quad Flat Pack. Consider the SX-A family architecture for applications needing 100% pin locking and full resource utilization. Evaluate the 350 MHz internal performance capability against system timing constraints. Verify that the antifuse technology aligns with the need for nonvolatile, one-time programmable configurations.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for low-power, high-performance applications. The SX-A series integrates CPLD functionality with FPGA flexibility using antifuse technology. Microchip Technology acquired Actel, continuing support for these devices in their portfolio. The SX-A family offers various capacity options ranging from 12,000 to 108,000 system gates.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as the standard speed variant or the -2 speed grade. For higher capacity needs, the A54SX72A series may be considered if pin compatibility allows. Cross-family migration to newer Microchip FPGA architectures requires schematic and code re-verification.
