A54SX16P-2TQG176

Overview

The A54SX16P-2TQG176 is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates at a maximum internal frequency of 350 MHz with a standard speed grade performance of 250 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package with a lead count of 176.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements
• Features deterministic timing with user-controllable delays and 100% pin locking capability
• Includes nonvolatile single-chip architecture with Actel Secure Programming Technology to prevent reverse engineering
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)

Applications

• 66 MHz PCI compliant designs
• Low-power high-performance embedded systems
• Industrial applications requiring mixed-voltage operation

Procurement Notes

Verify the specific ordering suffix 'G' indicates RoHS compliant packaging when sourcing this component. Confirm that the 'P' designation corresponds to the Plastic Quad Flat Pack variant within the SX-A family specifications. Ensure compatibility with Actel Designer software for programming and configuration.

Selection Notes

Select this model for designs requiring approximately 24,000 system gates with a 176-pin interface. The -2 speed grade offers approximately 25% faster performance than the standard grade. Consider the TQFP package constraints and verify thermal management requirements for the commercial temperature range if applicable.

Part Context

This component belongs to the Actel SX-A FPGA family, which provides a cost-effective single-chip solution using antifuse technology. The SX-A series is designed for applications needing low power consumption and high performance, integrating features previously found in multiple CPLDs or gate arrays into a single device.
