A54SX32A-FTQG176

Overview

The A54SX32A-FTQG176 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates with an internal performance of 350 MHz and supports mixed-voltage I/O at 2.5 V, 3.3 V, and 5 V. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and includes up to 2,012 dedicated flip-flops. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Provides deterministic timing through user-controllable routing resources including DirectConnect and FastConnect
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering
• Includes Boundary-Scan Testing compliance with IEEE Standard 1149.1 for diagnostic verification

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• High-performance designs requiring low power consumption
• Applications needing 100% resource utilization with pin locking

Procurement Notes

Verify the specific speed grade suffix associated with the FTQG176 package designation against current manufacturer documentation. Confirm RoHS compliance status as packaging options may vary between standard and lead-free versions. Ensure the temperature grade matches the intended operational environment requirements before finalizing procurement.

Selection Notes

Select this component when designing systems that require nonvolatile single-chip FPGA integration with mixed-voltage I/O capabilities. Consider the 350 MHz internal performance and 2,880 logic modules for complex logic implementations. Verify that the 176-pin TQFP package fits the available PCB footprint and thermal constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using metal-to-metal programmable antifuse technology. The family offers high-density logic resources with deterministic timing characteristics suitable for replacing multiple CPLDs or gate arrays in a single chip solution.
