A54SX08A-FTQG144

Overview

The A54SX08A-FTQG144 is a Field Programmable Gate Array from the SX-A family, featuring 12,000 system gates and 768 logic modules. It utilizes antifuse technology for nonvolatile configuration. The device supports mixed-voltage I/O standards including 3.3 V PCI, 5 V TTL, and 2.5 V LVCMOS2. It operates within a commercial temperature range of 0°C to +70°C. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package with a pitch of 1.4 mm.

Feature Summary

• Supports hot-swap capabilities for most I/O standards, allowing safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through user-controllable output slew rates and configurable weak pull-up or pull-down resistors at power-up.
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• Integration of 66 MHz PCI compliant designs
• High-performance state machine implementations
• Fast counter and data path logic circuits

Procurement Notes

Verify the specific ordering suffix 'F' against official documentation to confirm it denotes the standard speed grade variant. Confirm that the TQG144 designation corresponds to the RoHS-compliant thin quad flat pack package. Ensure the industrial or military temperature grades are not required if the application exceeds the commercial range limits.

Selection Notes

Select this model when a nonvolatile FPGA solution with high-speed internal routing is required. The architecture allows for 100% pin locking and resource utilization. Consider the available global clock networks and dedicated flip-flops for synchronous design requirements. Verify compatibility with existing PCB footprints for the 144-pin TQFP form factor.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers various gate counts ranging from 12,000 to 108,000 system gates. The SX-A series is designed for low-power, high-performance applications requiring single-chip integration.

Replacement Considerations

Check for other speed grades within the A54SX08A series, such as -1 or -2, if higher performance is needed. Verify package availability for alternative pin counts like the 100-pin TQFP if board space permits. Consult datasheets for cross-referencing with similar Actel antifuse devices.
