A54SX72A-1FG484M

The A54SX72A-1FG484M is a nonvolatile SX-A family FPGA in a 484-ball fine-pitch BGA (27×27) package designed for demanding, temperature-critical applications. It pairs 108,000 system gates and 6,036 logic elements with up to 360 user-programmable I/Os to deliver configurable digital logic capacity in a military-grade, surface-mount form factor.

Designed for systems that require deterministic timing, secure programming, and wide supply tolerance, the device supports mixed-voltage I/O and a wide operating temperature range for deployment in harsh environments.

Key Features

• Logic Capacity — 108,000 system gates and 6,036 logic elements with up to 2,012 dedicated flip-flops provide substantial programmable logic resources for complex designs.
• I/O and Interface Flexibility — Up to 360 user-programmable I/Os with configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 signaling; individual output slew-rate control and 5 V input tolerance where applicable.
• Performance — Datasheet-specified system performance of 250 MHz and internal performance up to 350 MHz for timing-critical functions.
• Power and Reliability — Power-up/power-down friendly operation (no required sequencing of supply voltages) and hot-swap–compliant I/Os simplify system power management and board-level integration.
• Security and Test — Actel Secure Programming technology with FuseLock™ for protection against reverse engineering and design theft, plus boundary-scan (IEEE 1149.1 JTAG) support for manufacturing test and in-system diagnostics.
• Package and Mechanical — 484-ball fine-pitch BGA (484-FPBGA, 27×27), surface-mount mounting; RoHS-compliant packaging.
• Electrical and Environmental — Voltage supply range of 2.25 V to 5.25 V and military-grade operating temperature of −55 °C to +125 °C.
• Resource Utilization and Timing — Support for up to 100% resource utilization and user-controllable, deterministic timing behavior for tightly constrained designs.
• Diagnostic Support — In-system diagnostic and verification capability (Silicon Explorer II support) to aid development and field troubleshooting.

Typical Applications

• Military and Aerospace Systems — Military-grade temperature range (−55 °C to +125 °C) and robust package make the device suitable for rugged, temperature-critical deployments.
• PCI-Compatible Systems — 66 MHz PCI compliance and configurable 3.3 V / 5 V PCI I/O support enable use in PCI-based interfaces and legacy host connections.
• Secure and Testable Designs — FuseLock™ secure programming and IEEE 1149.1 boundary-scan support simplify production testing and protect intellectual property during fielded operation.

Unique Advantages

• High Logic Density: 108,000 system gates with 6,036 logic elements provide significant on-chip logic for complex control, protocol bridging, and algorithm acceleration.
• Wide Voltage Tolerance: 2.25 V to 5.25 V supply range and configurable I/Os support mixed-voltage systems and simplify board-level integration across legacy and modern interfaces.
• Rugged Operational Range: Military-grade temperature rating and surface-mount BGA packaging support deployment in harsh environmental conditions.
• Nonvolatile, Secure Configuration: Single-chip nonvolatile FPGA architecture with FuseLock™ technology secures bitstream and reduces system-level configuration complexity.
• Deterministic Timing and Full Utilization: User-controllable timing and up to 100% resource utilization help meet tight latency and density requirements without unused logic overhead.
• Manufacturing and Field Diagnostics: Boundary-scan and in-system diagnostic capabilities improve test coverage and speed up fault isolation during bring-up and field maintenance.
