A54SX32A-TQG100I

Overview

The A54SX32A-TQG100I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and supports up to 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates at a standard speed grade with a maximum internal performance frequency of 350 MHz and a system performance of 250 MHz. It utilizes 0.22 μm / 0.25 μm CMOS technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V levels with 5 V input tolerance. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Features deterministic timing through unique local routing resources like DirectConnect and FastConnect for predictable signal propagation.
• Includes IEEE 1149.1 (JTAG) boundary-scan testing compliance for superior diagnostic and verification capabilities.

Applications

• High-performance logic integration replacing complex programmable logic devices (CPLDs).
• Systems requiring deterministic timing and fast counters or state machines.
• Applications needing secure programming to prevent reverse engineering via FuseLock technology.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) as defined in the official datasheet. Confirm the package type corresponds to the 100-pin TQFP form factor. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture before procurement.

Selection Notes

Select this component when 48,000 system gates are required with a 100-pin footprint. Consider the standard speed grade if 250 MHz system performance suffices. Verify that the antifuse technology aligns with non-reconfigurable design requirements. Check availability of the industrial grade variant for environmental constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are known for their high-density antifuse technology. The A54SX32A designation indicates the 48K gate capacity within the series, which also includes smaller (A54SX08A, A54SX16A) and larger (A54SX72A) variants. The TQG100I suffix specifies the Thin QFP package, Industrial temperature rating, and lead-free packaging status.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade may include other A54SX32A variants with different temperature ratings (e.g., Commercial C or Automotive A grades) if environmental conditions allow. Cross-family migration to newer Microchip FPGA architectures requires schematic and software redesign.
