A54SX16P-TQ144I

Overview

The A54SX16P-TQ144I 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 contains 1,452 logic modules (CLBs). The device supports up to 350 MHz internal performance with 250 MHz system performance. It features 113 user-programmable I/O pins and up to 2,012 dedicated flip-flops. Operating at 2.5 V, 3.3 V, or 5 V, it accommodates mixed-voltage I/O standards including 3.3 V/5 V PCI, 5 V TTL, and 3.3 V LVTTL. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing through unique DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Integrated security via FuseLock technology preventing reverse engineering and unauthorized design access.

Applications

• High-performance state machines and fast counters requiring deterministic timing
• Data path logic integration replacing multiple complex programmable logic devices
• PCI-compliant interface designs supporting 66 MHz operations

Procurement Notes

Verify the specific ordering suffix 'P' against official Microchip documentation to confirm package type and temperature grade alignment. Confirm RoHS compliance status as standard packaging may vary by production lot. Ensure the industrial temperature range (-40°C to +85°C) matches the application environment requirements before finalizing procurement.

Selection Notes

Select this device when a nonvolatile FPGA with high-speed internal routing is required. The SX-A architecture offers superior pin-locking capabilities compared to volatile FPGAs. Consider the 144-pin TQFP package constraints for PCB layout. Evaluate the 24,000 gate capacity against design complexity to ensure optimal resource utilization within the 1,452 CLB structure.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for low-power, high-performance applications. The family utilizes antifuse technology, distinguishing it from SRAM-based FPGAs. The A54SX16A variant represents a mid-range density option within the series, balancing logic capacity with speed and I/O flexibility for embedded control and interface tasks.

Replacement Considerations

Direct replacements include other A54SX16A variants with different speed grades or packages, such as A54SX16A-TQ144C for commercial temperature or A54SX16A-PQ208 for increased I/O count. Verify that any substitute maintains the same antifuse programming toolchain compatibility and pinout if form-factor retention is critical.
