A54SX32A-BGG329

Overview

The A54SX32A-BGG329 is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It supports up to 249 user-programmable I/Os and operates with internal clock frequencies up to 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 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.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power 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 and design theft.

Applications

• 66 MHz PCI compliant designs
• Low-power high-performance single-chip solutions
• Systems requiring mixed-voltage I/O interfaces

Procurement Notes

Verify the specific speed grade suffix associated with the BGG329 package variant, as standard speed grades are available alongside faster options. Confirm RoHS compliance status if required by environmental regulations, noting that 'G' indicates lead-free packaging. Ensure the application temperature range matches the commercial grade indicated by the blank suffix.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are required in a 329-pin PBGA form factor. Consider the SX-A architecture's nonvolatile antifuse nature for secure, single-chip implementations. Evaluate the 350 MHz internal performance capability against specific timing constraints for complex logic integration.

Part Context

This component belongs to the Actel SX-A FPGA family, which offers cost-effective, low-power solutions using antifuse technology. The SX-A series is designed to integrate CPLD and FPGA functionalities into a single chip, supporting various I/O standards including 3.3V/5V PCI and 5V TTL.
