A54SX32A-2BGG329I

Overview

The A54SX32A-2BGG329I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The device supports up to 249 user-programmable I/O pins and includes 1,080 dedicated flip-flops. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and functions within a voltage range of 2.25 V to 2.75 V. The component is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and is rated for industrial temperature operation from -40°C to +85°C.

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 power-up/down without sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required performance level, as it indicates approximately 25% faster operation than standard speed. Confirm that the 'I' suffix correctly matches the industrial temperature range requirement (-40°C to +85°C). Ensure the PBGA329 package dimensions align with the target PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are sufficient for the design. The -2 speed grade is appropriate for designs requiring higher clock frequencies up to 250 MHz system performance. Consider the PBGA329 package if high pin count density is needed. Verify compatibility with Actel Designer software for place-and-route constraints and ensure the antifuse technology suits the nonvolatile configuration needs.

Part Context

This part belongs to the Actel SX-A FPGA family, which uses metal-to-metal programmable antifuse technology. The A54SX32A variant specifically offers 48,000 system gates, positioning it between the smaller A54SX16A and larger A54SX72A devices. The SX-A family is characterized by its sea-of-modules architecture and high-speed interconnect capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Other members of the A54SX32A series with different speed grades or packages may serve as alternatives if electrical and physical constraints allow.
