A54SX32-BGG329I

Overview

The A54SX32-BGG329I is a Field Programmable Gate Array from the Actel SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum internal frequency of 350 MHz with a typical system 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 with 5 V input tolerance. It is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without supply voltage sequencing requirements
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• Includes boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• 66 MHz PCI compliant single-chip solutions
• Low-power, high-performance designs requiring mixed-voltage I/O support
• Applications necessitating nonvolatile, single-chip FPGA integration

Procurement Notes

Verify component authenticity through official Microchip channels or authorized distributors. Confirm that the specific ordering suffix matches the required speed grade, package type, and industrial temperature range specifications. Ensure compliance with relevant environmental regulations applicable to the intended deployment region.

Selection Notes

Select this model when 48,000 system gates and 249 user I/Os are required within a 329-pin BGA footprint. Choose the industrial temperature grade variant for environments operating between -40°C and +85°C. Consider the 350 MHz internal clock capability for high-speed logic processing needs.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The SX-A series offers a sea-of-modules architecture with dedicated routing resources like DirectConnect and FastConnect to optimize signal propagation delays and maximize logic density.

Replacement Considerations

Consult the official datasheet for alternative part numbers within the SX-A family that offer different speed grades or package options. Verify compatibility with existing PCB footprints and design constraints before substituting.
