A54SX32-BG329I

Overview

The A54SX32-BG329I is a Field Programmable Gate Array from the Actel 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 (CLBs). The device supports up to 249 user-programmable I/O pins and features three global clock networks. It operates with mixed-voltage support for 2.5 V, 3.3 V, and 5 V supplies, including 5 V input tolerance. The component is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and is rated for industrial temperature ranges.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap capabilities and power-up/down friendly operation without requiring supply voltage sequencing.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II and boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG).
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• 66 MHz PCI Compliant System Integration
• Deterministic User-Controllable Timing Applications
• Low-Power High-Performance Designs

Procurement Notes

Verify the specific speed grade suffix associated with the BG329 package, as standard speed grades are indicated by a blank space while faster variants use numerical suffixes. Confirm that the 'I' designation corresponds to the required industrial temperature range of -40°C to +85°C. Ensure compatibility with the 0.22/0.25 micron process technology specifications provided in the SX-A datasheet.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are required within a 329-pin BGA footprint. Consider the SX-A architecture's deterministic timing and 100% pin-locking capabilities for designs needing predictable performance. Verify that the nonvolatile antifuse technology aligns with security requirements against reverse engineering compared to volatile FPGA alternatives.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance applications. The family utilizes antifuse technology to provide nonvolatile configuration, distinguishing it from SRAM-based FPGAs. The SX-A series offers various gate counts and package options to integrate CPLD and FPGA functionality into a single chip.
