A54SX32A-2BG329

Overview

The A54SX32A-2BG329 is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (1,800 combinatorial cells and 1,080 dedicated flip-flops). The device supports up to 249 user-programmable I/O pins and features three global clock networks. It operates with internal performance up to 350 MHz and system performance up to 250 MHz. The component utilizes a 329-pin Plastic Ball Grid Array (PBGA) package with a 1.27 mm pitch.

Feature Summary

• Supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance and drive strength.
• Features hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• High-performance designs requiring low power consumption
• Applications needing 100% resource utilization with pin locking

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm temperature grade and packaging compliance. Confirm that the -2 speed grade meets the required timing specifications for the target application. Ensure the PBGA329 package dimensions align with the PCB footprint design. Check for any relevant product change notifications or discontinuation notices associated with this part number.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are required in a 329-pin BGA package. The -2 speed grade offers approximately 25% faster performance than the standard grade. Verify that the Industrial temperature range (-40°C to +85°C) matches the environmental requirements. Consider the nonvolatile antifuse architecture if security and zero standby power are critical design constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi and subsequently Microchip Technology. The SX-A series is characterized by its metal-to-metal programmable antifuse interconnect, offering high performance and security compared to volatile SRAM-based FPGAs.
