A54SX32A-1BGG329I

Overview

The A54SX32A-1BGG329I is a Field Programmable Gate Array from the Microchip Actel SX-A family, utilizing antifuse technology. It provides 48,000 system gates and 2,880 logic modules within a 329-pin Plastic Ball Grid Array (PBGA) package. The device supports up to 249 user-programmable I/O pins and operates at a maximum system performance frequency of 250 MHz with an internal clock capability of 350 MHz. It functions on a 0.22 μm / 0.25 μm CMOS process and requires a core supply voltage between 2.25 V and 2.75 V. The -1 speed grade indicates approximately 15% faster performance than the standard grade, and the 'I' suffix designates an industrial temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system damage.
• Features deterministic timing through unique DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Includes IEEE 1149.1 (JTAG) boundary-scan testing compliance and FuseLock security technology to prevent reverse engineering.

Applications

• High-performance digital signal processing and control applications requiring low latency.
• Industrial automation systems necessitating robust operation across wide temperature ranges.
• Communication infrastructure equipment utilizing 66 MHz PCI compliant interfaces.
• Prototyping and production designs replacing complex CPLDs or gate arrays.

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status as packaging options may vary. Check for end-of-life notifications or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when a nonvolatile FPGA architecture is required to eliminate configuration boot times associated with volatile devices. Ensure the design fits within the 48,000 system gate limit and utilizes the available 249 I/Os efficiently. Consider the -1 speed grade if timing constraints exceed the standard grade capabilities but do not require the fastest available option.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their high-density antifuse technology and mixed-voltage I/O support. The SX-A series bridges the gap between CPLDs and larger FPGAs, offering deterministic performance and high security. The A54SX32A variant specifically targets mid-range logic density applications requiring significant I/O flexibility.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be sought from the A54SX32A product line. Verify that any substitute maintains the 329-pin PBGA footprint and meets the industrial temperature specifications. Cross-family migration may require schematic and layout modifications due to architectural differences.
