A54SX08-1TQG176I

Overview

The A54SX08-1TQG176I is an industrial-grade Field Programmable Gate Array from the Microsemi SX-A family, featuring 12,000 system gates and 768 logic modules. It operates within a voltage range of 2.25V to 5.25V and supports up to 113 user-programmable I/O pins in a 176-pin Thin Quad Flat Pack (TQFP) package. The device provides deterministic timing with a maximum system performance frequency of 250 MHz and internal clock frequencies reaching 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).
• Provides secure programming via Actel FuseLock technology to prevent reverse engineering.

Applications

• High-performance digital logic integration requiring deterministic timing.
• PCI-compliant interface designs operating at 66 MHz.
• Systems requiring hot-swappable peripheral connections.
• Industrial control applications necessitating extended temperature range operation.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the package type corresponds to the 176-pin TQFP variant. Ensure compatibility with existing design tools for the SX-A family architecture before procurement.

Selection Notes

Select this component when 12,000 system gates are sufficient for the target logic density. The -1 speed grade offers approximately 15% faster performance than the standard grade. Verify that the 176-pin TQFP footprint aligns with the PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the Microsemi SX-A FPGA family, which utilizes metal-to-metal programmable antifuse interconnect elements. The family includes devices ranging from 8,000 to 108,000 system gates, offering various package options including PQFP, TQFP, PBGA, and FBGA configurations.

Replacement Considerations

Compatible variants within the same package include the A54SX08A-1TQG176I (Commercial grade) or A54SX08A-2TQG176I (Higher speed grade). Cross-family replacements require verification of pinout compatibility and logic resource equivalence.
