A54SX08A-2TQG144I

Overview

The A54SX08A-2TQG144I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 12,000 system gates and 768 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It features a maximum system performance frequency of 250 MHz and an internal clock frequency of 350 MHz. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Supports mixed-voltage I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes deterministic timing capabilities with user-controllable output slew rates and configurable weak pull-up/pull-down resistors.
• Integrates boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration requiring nonvolatile configuration.
• Systems requiring hot-swappable interface capabilities.
• Industrial control applications operating within extended temperature ranges.
• PCI-compliant peripheral designs.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with existing design tools and verify that the antifuse technology aligns with long-term availability requirements for the target application.

Selection Notes

Select this component when a nonvolatile FPGA solution with high-speed deterministic timing is required. Consider the 12,000 gate capacity and 113 I/O limit for moderate complexity designs. Verify voltage domain requirements as the device supports multiple I/O standards but requires appropriate supply voltage selection during configuration.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse technology. The family offers varying capacities from 8,000 to 108,000 system gates. The A54SX08A variant represents the entry-level density in this series, providing a cost-effective single-chip solution for low-power, high-performance designs.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX08A series, such as A54SX08A-1TQG144I or A54SX08A-TQG144I, provided timing constraints are met. Cross-family migration to newer Microchip FPGA architectures may require significant redesign due to architectural differences.
