A54SX72A-FG256I

The A54SX72A-FG256I is an SX-A family FPGA from Microchip Technology delivered in a 256-pin fine-pitch BGA (17 × 17 mm) package. It provides a nonvolatile, single-chip FPGA solution with substantial logic capacity and flexible I/O for mixed-voltage systems.

Targeted at industrial applications, this device combines 108,000 system gates and 6,036 logic elements with 203 user I/Os, offering a high-capacity programmable fabric with industrial temperature rating and wide supply-voltage tolerance.

Key Features

• Core capacity — 108,000 system gates and 6,036 logic elements provide significant programmable logic resources for complex glue logic, protocol bridging, and custom datapaths.
• User I/O and packaging — 203 user-programmable I/Os in a 256-pin fine-pitch BGA (256-FPBGA, 17×17) package support dense board-level integration and high pin counts in a compact footprint.
• Voltage and I/O compatibility — Supports mixed-voltage operation across a 2.25 V to 5.25 V supply range with configurable I/O for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling.
• Industrial temperature grade — Rated for operation from −40 °C to 85 °C, suitable for industrial-temperature environments.
• Nonvolatile, single-chip configuration — Built-in nonvolatile configuration eliminates the need for external configuration memory and supports power-up/power-down friendly operation without supply sequencing.
• Family performance characteristics — SX-A family performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance (family specification).
• System and test features — Hot-swap compliant I/Os, boundary-scan (IEEE 1149.1) support, and power-up weak pull-up/pull-down options enable robust system integration and testability.
• Security and manufacturing features — Includes Actel Secure Programming Technology with FuseLock™ for design protection and anti-reverse-engineering support (family feature).
• On-chip memory — No embedded RAM bits (total RAM bits: 0), enabling deterministic, register- and logic-based designs.

Typical Applications

• PCI and legacy bus interfaces — 66 MHz PCI compliance and configurable I/O levels enable use as a protocol bridge or interface controller on PCI-based boards.
• Mixed-voltage interface hubs — Mixed-voltage operation and 5 V-tolerant I/Os make the device suitable for interconnecting components operating at 2.5 V, 3.3 V, and 5 V domains.
• Industrial control and automation — Industrial temperature rating and hot-swap compliant I/Os support deployment in factory automation and control systems requiring robust environmental performance.
• Security-conscious embedded systems — Nonvolatile configuration and FuseLock secure programming offer protection for designs where IP protection is important.

Unique Advantages

• High logic density: 108,000 system gates and 6,036 logic elements deliver capacity for complex combinational and sequential logic without multiple devices.
• Flexible I/O and voltage support: Configurable I/O standards and a wide supply range simplify mixed-voltage board designs and reduce level-shifting requirements.
• Single-chip nonvolatile configuration: Eliminates external configuration memory and simplifies power sequencing and system bring-up.
• Industrial readiness: −40 °C to 85 °C operating range and industrial grade packaging support deployments in harsh environments.
• Design protection: Built-in secure programming (FuseLock) helps prevent reverse engineering and protects design IP.
