A54SX72A-1FGG256I

The A54SX72A-1FGG256I is a nonvolatile SX-A family FPGA in a 256-pin fine-pitch BGA package, offering a high-density, reprogrammable logic solution for industrial embedded systems. Built on the SX-A architecture, this device provides a combination of logic capacity, flexible mixed-voltage I/O and system-level features that address interface bridging, control and in-system programmable logic needs.

Key value comes from its 108,000 system gates equivalent and 6,036 logic elements, support for mixed 2.5/3.3/5 V operation, and industrial-grade temperature range—enabling robust designs that require dense logic, configurable I/O and secure nonvolatile configuration.

Key Features

• High Logic Capacity — 108,000 system gates equivalent and 6,036 logic elements provide substantial programmable logic resources for complex glue logic, state machines and custom datapaths.
• User I/O and Mixed-Voltage Support — 203 user I/Os on this package with configurable I/O support across 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, enabling mixed-voltage system interfacing.
• Nonvolatile Single-Chip Solution — SX-A family nonvolatile architecture retains configuration without external configuration memory, simplifying board design and system initialization.
• Package and Mounting — 256-pin fine-pitch BGA (256-FPBGA, 17×17) in a surface-mount form factor for compact board layouts and reliable soldered connections.
• Wide Supply Range — Operates from 2.25 V to 5.25 V, providing design flexibility across different power domains and legacy signaling requirements.
• Industrial Temperature Grade — Specified for operation from −40 °C to 85 °C, suitable for industrial environments.
• System-Level Features (SX-A family) — Hot-swap compliant I/Os, power-up/power-down friendly behavior (no supply sequencing required), IEEE 1149.1 JTAG boundary-scan, and support for 66 MHz PCI signaling as part of the SX-A feature set.
• Security and Test — Actel Secure Programming Technology with FuseLock™ in the SX-A family prevents reverse engineering and supports in-system diagnostics and verification.
• Standards and Compliance — RoHS-compliant device packaging.

Typical Applications

• Industrial Control — Implements custom control logic, sequencing and interface glue in automation and factory equipment while meeting industrial temperature requirements.
• Mixed-Voltage Interface Bridging — Bridges legacy 5 V subsystems with modern 2.5/3.3 V logic using configurable I/O and wide supply range.
• Embedded System Glue Logic — Provides dense programmable logic for bus arbitration, protocol adapters and custom peripherals in compact board layouts.
• PCI-Capable Systems — Useful in systems requiring PCI-level interfacing thanks to SX-A family 66 MHz PCI compliance.
• Secure In-System Programmability — Protects design IP and supports secure field updates via the family’s Secure Programming features.

Unique Advantages

• High integration density: 108,000 system gates and 6,036 logic elements reduce external glue logic and lower BOM complexity.
• Flexible power and I/O: 2.25–5.25 V supply range and configurable I/O enable straightforward integration into mixed-voltage systems.
• Nonvolatile configuration: Single-chip, nonvolatile architecture removes the need for external configuration memory and simplifies system boot behavior.
• Industrial readiness: Specified operation from −40 °C to 85 °C supports deployment in industrial environments.
• Security and testability: Built-in FuseLock security and IEEE 1149.1 boundary-scan support protect IP and simplify production testing.
• Compact, board-friendly package: 256-FPBGA (17×17) surface-mount package enables dense, reliable PCB layouts.
