A54SX16P-TQ176

Overview

The A54SX16P-TQ176 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 a maximum internal clock frequency of 350 MHz with a typical system performance of 250 MHz. It features up to 2,012 dedicated flip-flops and 147 user-programmable I/Os within a 176-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance
• Features hot-swap compliant I/Os allowing power-up/down without supply sequencing
• Includes nonvolatile single-chip architecture with Actel FuseLock security technology
• Provides deterministic timing through segmented routing and global clock networks

Applications

• 66 MHz PCI compliant designs
• Low-power high-performance embedded systems
• Industrial applications requiring mixed-voltage I/O standards

Procurement Notes

Verify the specific speed grade suffix associated with the TQ176 package configuration. Confirm RoHS compliance status as standard packaging may differ from lead-free options. Ensure the ordering code matches the required temperature range for the target environment.

Selection Notes

Select this model for designs requiring 24,000 system gates with a 176-pin footprint. Consider the -2 speed grade for higher performance requirements compared to the standard grade. Verify that the 147 available user I/Os meet the interface count needs.

Part Context

This component 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 across different package types including PQFP, TQFP, PBGA, and FBGA.

Replacement Considerations

Check for availability of A54SX16P-VQ100I or A54SX16P-TQ144X79 if pin counts allow. Verify functional equivalence regarding gate density and I/O configurations before substitution.
