A54SX32-TQ144I

The A54SX32-TQ144I is an industrial-grade, nonvolatile FPGA from the SX-A family designed for embedded logic integration and mixed-voltage I/O applications. It provides 48,000 system gates implemented across 2,880 logic elements and offers 113 user I/O pins in a 144-pin LQFP surface-mount package.

With a wide supply range (3 V to 5.5 V), support for mixed 2.5 V/3.3 V/5 V signaling, and an operating temperature range of –40 °C to 85 °C, the device targets industrial embedded systems and applications that require reliable, single-chip programmable logic with configurable I/O behavior.

Key Features

• Core Performance – Series-level performance includes up to 250 MHz system performance and 350 MHz internal performance, providing headroom for timing-critical logic (series specification).
• Logic Capacity – 48,000 system gates implemented across 2,880 logic elements to consolidate glue logic, custom state machines, and interface bridging.
• User I/O and Interface Flexibility – 113 user I/Os with hot-swap–compliant I/Os and configurable support for multiple I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 (series features).
• Voltage and Power – Operates from 3 V to 5.5 V and supports mixed-voltage operation (2.5 V, 3.3 V, 5 V) with 5 V input tolerance and drive strength (series features).
• Nonvolatile Single-Chip Configuration – Single-chip, nonvolatile architecture eliminates the need for external configuration memory (series feature), simplifying board design and system power-up behavior.
• Robust Package and Thermal Range – 144-pin LQFP surface-mount package (supplier device package noted as 144-TQFP, 20×20) and industrial temperature grade (–40 °C to 85 °C).
• System Diagnostics and Security – Series-level in-system diagnostic and verification capability (Silicon Explorer II) and secure programming technology (FuseLock™) to support design protection and verification (series features).
• Standards Compliance – Series includes 66 MHz PCI compliance for legacy or PCI-based interfacing requirements.
• Environmental – RoHS compliant.

Typical Applications

• Industrial Control – Use as programmable logic for factory automation, motor control interfaces, and process-control glue logic where industrial temperature ratings and robust I/O are required.
• Mixed-Voltage I/O Bridging – Provide level translation and protocol interfacing between 2.5 V, 3.3 V, and 5 V subsystems thanks to mixed-voltage support and 5 V input tolerance.
• Legacy PCI and Peripheral Interfaces – Implement PCI-compliant bridging or peripheral control logic for designs that require 66 MHz PCI signaling support (series feature).
• Embedded System Integration – Consolidate CPLD/ASIC replacement logic, custom peripherals, or state machines into a single nonvolatile FPGA to reduce BOM and board complexity.

Unique Advantages

• Highly integrated single-chip solution: Nonvolatile configuration on-chip removes the need for external configuration memories and simplifies start-up behavior.
• Flexible I/O and mixed-voltage support: Configurable I/O standards and 5 V tolerance enable direct interfacing to a wide range of legacy and modern devices.
• Designed for industrial use: Industrial temperature rating (–40 °C to 85 °C) and surface-mount package support deployment in harsh environments.
• Deterministic timing control: Series-level capability for user-controllable, deterministic timing supports predictable performance in time-sensitive designs.
• In-system diagnostics and security: Built-in diagnostic/verification tools and secure programming features help protect IP and simplify in-system verification.
• RoHS compliant: Meets environmental compliance requirements for modern electronics manufacturing.
