A54SX32-BG313

Overview

The A54SX32-BG313 is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (comprising 1,800 combinatorial cells and 1,080 dedicated flip-flops). The device supports up to 249 user-programmable I/Os and features three global clock networks. It operates with internal performance up to 350 MHz and system performance up to 250 MHz. The component is housed in a 329-pin Plastic Ball Grid Array (PBGA) package.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing for predictable signal propagation.
• Integrates IEEE 1149.1 Boundary-Scan Testing capabilities for in-system diagnostic verification.

Applications

• 66 MHz PCI compliant interface integration
• High-performance state machine and counter logic implementation
• Secure single-chip solutions requiring reverse engineering protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. The BG designation indicates a 1.27 mm pitch Plastic Ball Grid Array package. Confirm RoHS status and lead-free packaging requirements if applicable to the target assembly process.

Selection Notes

Select this device when designs require high-density logic within a nonvolatile antifuse FPGA architecture. Consider the 2880 CLB capacity and 249 I/O limit for complex digital control applications. Ensure the 329-pin PBGA footprint fits the PCB layout constraints and thermal management requirements for the selected speed grade.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family includes devices ranging from 12,000 to 108,000 system gates, offering various package options including PQFP, TQFP, PBGA, FBGA, and CQFP formats to suit different pin count and form factor needs.

Replacement Considerations

Compatible alternatives within the same family include the A54SX32-P1BGG313 and A54SX32-P1BGG329. Verify that the substitute part number matches the required speed grade and package pin count before substitution.
