A54SX16A-2TQG144I

The A54SX16A-2TQG144I is an SX-A family nonvolatile FPGA offered in a 144-pin LQFP/TQFP package, engineered for industrial applications requiring deterministic logic and flexible I/O. It provides 24,000 system gates and 1,452 logic elements, with 113 user I/O pins and support for mixed-voltage operation.

Designed for embedded control, interface logic and system integration, this device combines single-chip nonvolatile configuration, hot-swap–capable I/Os and power-up/power-down friendly operation to simplify board-level design and reliability in industrial temperature environments.

Key Features

• Logic Capacity  24,000 system gates with 1,452 logic elements (combinatorial cells and logic modules) to implement medium-density logic functions.
• User I/O  113 programmable I/O pins with configurable weak pull-up or pull-down at power-up and individual output slew rate control.
• Performance  Documented SX-A family performance includes up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Nonvolatile Single-Chip Configuration  Built-in nonvolatile configuration removes the need for external configuration memory and supports in-system programming and diagnostics.
• Voltage and I/O Flexibility  2.25 V to 5.25 V supply range with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; 5 V input tolerance and 5 V drive strength options are supported by the SX-A architecture.
• System Integration  Hot-swap compliant I/Os and power-up/down friendly operation reduce sequencing constraints for complex power rails.
• Reliability & Test  Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capabilities as provided in the SX-A family documentation.
• Package & Mounting  144-pin LQFP (also referenced as 144-TQFP 20×20) surface-mount package suited for standard PCB assembly processes.
• Industrial Grade  Qualified for an operating temperature range of −40 °C to +85 °C and RoHS compliant.

Typical Applications

• Industrial Control  Use for control logic, sequencing and interface glue in factory automation and motor-control subsystems that require industrial temperature operation and deterministic timing.
• Interface & Bus Bridging  Implement protocol adaptation, glue logic and PCI-attached peripherals leveraging the SX-A family’s PCI support and flexible I/O standards.
• Embedded System Integration  Consolidate glue logic and custom peripherals into a single nonvolatile FPGA to reduce BOM and simplify board-level configuration.
• Board-Level Test & Diagnostics  Leverage boundary-scan (IEEE 1149.1) and the SX-A family in-system diagnostic features for production test and field verification.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates external configuration memory and streamlines power-up behavior and system architecture.
• Flexible mixed-voltage I/O: Supports multiple I/O standards and a wide supply range (2.25 V–5.25 V), enabling easy interface to legacy and modern logic levels.
• Deterministic timing: SX-A family features user-controllable timing behavior suitable for designs that require predictable performance.
• Hot-swap capable I/Os: I/O design helps simplify integration with systems that require live-board insertion or complex power sequencing.
• Industrial temperature rating: Rated −40 °C to +85 °C for deployment in industrial environments.
• RoHS compliant packaging: Supports environmental and supply-chain requirements.
