The A54SX72A-1FG256I is a nonvolatile SX-A family FPGA offered in a 256-ball fine-pitch BGA package. This industrial-grade device integrates 6,036 logic elements (combinatorial cells) and 108,000 system gates with up to 203 user-programmable I/O pins, delivering a high-density programmable fabric for mixed-voltage systems.

Designed for applications that require configurable I/O, secure single-chip programming, and predictable timing, the A54SX72A-1FG256I supports mixed 2.5 V, 3.3 V and 5 V operation with 5 V input tolerance and features that simplify power sequencing and system integration.

Key Features

• Core Capacity — 6,036 logic elements (combinatorial cells) and 108,000 system gates provide substantial programmable logic for glue logic, control functions, and medium-complexity FPGA designs.
• I/O and Interface Flexibility — Up to 203 user I/Os with configurable support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; 5 V input tolerance enables mixed-voltage system integration.
• Nonvolatile, Single-Chip Configuration — SX-A family nonvolatile architecture removes the need for external configuration memory, simplifying board design and improving system robustness.
• Performance Characteristics — Series-specified system performance up to 250 MHz and internal performance up to 350 MHz (series-level specification) for responsive logic and timing-critical functions.
• Power and Reliability — Power-up/power-down friendly operation requires no sequencing of supply voltages; hot-swap compliant I/Os support insertion and removal scenarios.
• Security and Test — Built-in secure programming (FuseLock™) to help prevent reverse engineering and design theft, and boundary-scan (IEEE 1149.1) support for production test and in-system diagnostics.
• Package and Environmental — 256-ball fine-pitch BGA (1.0 mm FPBGA, 17 × 17) surface-mount package; rated for industrial operation from −40 °C to +85 °C and RoHS compliant.
• Voltage Supply Range — Flexible supply tolerance from 2.25 V to 5.25 V to accommodate a variety of board power architectures.

Typical Applications

• PCI-Compatible Peripheral Logic — Use the device's 66 MHz PCI compliance and configurable I/O voltage support to implement PCI interface logic and peripherals.
• Mixed-Voltage Glue and Interface Bridging — Ideal for systems that require level translation or protocol bridging between 2.5 V, 3.3 V and 5 V domains thanks to 5 V input tolerance and mixed-voltage operation.
• Secure Embedded Control — Nonvolatile single-chip configuration combined with FuseLock™ secure programming is well-suited for embedded controllers and designs where IP protection is important.
• Industrial Control and Monitoring — Industrial temperature rating (−40 °C to +85 °C) and robust I/O features make this FPGA suitable for factory automation, instrumentation, and industrial control applications.

Unique Advantages

• High Logic Density: 6,036 logic elements and 108,000 system gates provide significant programmable resources in a compact FBGA package, reducing the need for multi-chip solutions.
