A54SX16P-1VQ100I

Overview

The A54SX16P-1VQ100I is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 1,452 configurable logic blocks. It operates at a maximum frequency of 250 MHz with an internal performance of 350 MHz. The device supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V, with 81 user-programmable I/Os in a 100-pin TQFP package. It utilizes nonvolatile antifuse technology for permanent configuration.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Supports hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing
• Provides deterministic timing with up to 100% resource utilization and pin locking
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)

Applications

• Low-power, high-performance designs requiring cost-effective integration
• Systems needing 66 MHz PCI compliance
• Applications requiring secure programming to prevent reverse engineering

Procurement Notes

Verify the specific ordering suffix 'G' for RoHS compliance if required, as standard packaging may differ. Confirm the temperature grade 'I' matches industrial requirements (-40°C to +85°C). Check current availability status as older FPGA families may have limited production runs or end-of-life notifications.

Selection Notes

Select this model for designs requiring 24,000 system gates within a 100-pin footprint. Ensure the design leverages the 2.5 V, 3.3 V, and 5 V mixed-voltage capabilities. Consider the 250 MHz speed grade for timing closure. Verify that the antifuse technology aligns with the need for nonvolatile configuration without external memory.

Part Context

This component belongs to the Actel SX-A family of FPGAs, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. The family ranges from 12,000 to 108,000 system gates. The A54SX16A variant specifically offers 24,000 system gates and 1,452 CLBs, positioned between the smaller A54SX08A and larger A54SX32A devices.

Replacement Considerations

Direct replacements within the same package and gate count are limited due to the discontinuation of the -3 speed grade. Consider the A54SX16A series variants with different speed grades (e.g., -1, -2) or temperature grades if available. Cross-family migration to newer Microchip FPGA architectures may be necessary for long-term supply assurance.
