A54SX32-1BGG329I

Overview

The A54SX32-1BGG329I is a Field Programmable Gate Array from the Actel SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates with a maximum internal clock frequency of 350 MHz and supports up to 249 user-programmable I/O pins. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and accommodates mixed-voltage operation at 2.5 V, 3.3 V, and 5.0 V with 5.0 V input tolerance. It is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and is rated for industrial temperature ranges (-40°C to +85°C).

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Provides deterministic timing through user-controllable delays and 100% resource utilization with pin locking.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• 66 MHz PCI compliant single-chip integration solutions
• High-performance state machines and fast counters requiring low propagation delay
• Systems requiring mixed-voltage I/O interfacing between 2.5 V, 3.3 V, and 5.0 V domains

Procurement Notes

Verify the specific speed grade suffix '1' indicates approximately 15% faster performance than standard speed. Confirm the 'I' suffix denotes the industrial temperature range of -40°C to +85°C. Ensure the PBGA329 package dimensions match the target PCB footprint. Check for RoHS compliance status as packaging options may vary by manufacturing lot.

Selection Notes

Select this model when 48,000 system gates are required with high-speed performance exceeding standard grades. The 329-pin BGA package is suitable for designs needing up to 249 I/Os. Consider the SX-A architecture's nonvolatile antifuse nature if configuration bitstream interception prevention is necessary. Verify that the 350 MHz internal clock capability meets the system timing constraints.

Part Context

This component belongs to the Actel SX-A FPGA family, which uses metal-to-metal programmable antifuse interconnect elements. The A54SX32 variant specifically offers 48,000 system gates, positioning it between the A54SX16A and A54SX72A in terms of capacity within the series.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other speed grades or package variants within the A54SX32A series only if electrical parameters and pinouts are verified compatible.
