A54SX16-TQG176

The A54SX16-TQG176 is a commercial-grade, nonvolatile SX-A family FPGA offered in a 176-pin thin QFP package. It provides a compact, surface-mount programmable logic solution with 24,000 system gates and 1,452 logic elements for embedded control, I/O aggregation, and custom glue-logic functions.

Designed for mixed-voltage systems, the device supports a wide supply range (3 V to 5.25 V), up to 147 user I/Os, and on-chip features that simplify board-level integration while preserving deterministic timing and in-system diagnostics.

Key Features

• Core Logic: 1,452 logic elements delivering approximately 24,000 system gates for implementing combinational and sequential logic in a compact FPGA.
• I/O Density and Flexibility: Up to 147 user I/Os with configurable I/O support for multiple voltage standards, enabling mixed-voltage interfacing on a single device.
• Voltage and Power: Operates from 3 V to 5.25 V and is power-up/power-down friendly with no supply sequencing required.
• Package and Mounting: 176-pin LQFP (thin QFP) surface-mount package (24 × 24 mm footprint) suitable for space-constrained board designs.
• Performance: Series-level performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as documented for the SX-A family.
• Nonvolatile Single-Chip Solution: Built-in nonvolatile configuration memory removes external configuration dependencies and simplifies system boot behavior.
• System Reliability and Test: Hot-swap compliant I/Os, boundary-scan (IEEE 1149.1) support, and in-system diagnostic/verification capability referenced in the SX-A family documentation.
• Security: Series-level secure programming technology (FuseLock™) for protection against reverse engineering and unauthorized readout, as described in the family datasheet.
• Environmental Compliance: RoHS-compliant construction and commercial operating temperature range of 0 °C to 70 °C.

Typical Applications

• Embedded Control: Implement control logic, state machines, and custom peripherals where a compact, nonvolatile FPGA is required.
• Legacy and Bus Bridging: Support for PCI-related signaling and mixed-voltage I/O makes the device suitable for bridging legacy interfaces and peripheral buses.
• Communications and Networking Peripherals: Use as protocol glue, custom packet processing, or interface aggregation in communications equipment.
• Test and Measurement: On-chip deterministic timing and boundary-scan support facilitate development of instrumentation and bench-top test systems.

Unique Advantages

• Compact, High-Logic Density: 1,452 logic elements and 24,000 system gates in a 176-LQFP package reduce board area compared with multi-chip solutions.
• Mixed-Voltage I/O Support: Configurable I/Os and a wide supply range allow direct interfacing to 5 V and 3.3 V domains without extra level-shifting components.
• Nonvolatile Configuration: Single-chip nonvolatile architecture eliminates external configuration memory and simplifies system startup behavior.
• Design Security: Family-level secure programming (FuseLock™) provides protection against unauthorized design access and reverse engineering.
• Testability and Diagnostics: Boundary-scan (IEEE 1149.1) plus in-system diagnostic features help reduce bring-up time and ease board-level validation.
• Regulatory-Friendly: RoHS-compliant construction supports environmental directives for modern assemblies.
