A54SX72A-FGG484M

The A54SX72A-FGG484M is a nonvolatile SX-A family FPGA providing 108,000 system gates and 6,036 logic elements in a 484-ball fine-pitch BGA. Designed for military-grade and high-reliability systems, this device combines high gate density, up to 360 user-programmable I/Os and deterministic timing features for demanding embedded and interface applications.

Key value propositions include single-chip nonvolatile configuration, support for mixed-voltage I/O, and operation across a wide supply and temperature range—enabling deployment in harsh environments where reliability and configurability matter.

Key Features

• Core Performance — System performance up to 250 MHz and internal performance up to 350 MHz, providing headroom for timing-critical logic.
• Logic Capacity — 108,000 available system gates and 6,036 logic elements with up to 2,012 dedicated flip-flops for complex logic implementation.
• I/O and Interface Flexibility — Up to 360 user-programmable I/Os; configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 standards, with 5 V input tolerance and 5 V drive strength.
• Power and Voltage — Wide supply voltage support from 2.25 V to 5.25 V and power-up/power-down friendly operation with no sequencing required for supply voltages.
• Package and Mounting — 484-ball fine-pitch BGA package (484-FPBGA (27×27)), surface-mount mounting type suited for compact board designs.
• Temperature and Grade — Military grade device with an operating temperature range of −55 °C to 125 °C for demanding environmental conditions.
• System Reliability & Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic and verification capability using Silicon Explorer II.
• Security — Actel Secure Programming Technology with FuseLock™ to protect design IP against reverse engineering.
• PCI Compatibility — 66 MHz PCI compliant for integration with PCI-based interfaces.
• On-chip Memory — No embedded RAM on-chip (Total RAM bits: 0), enabling predictable resource allocation for logic and flip-flop usage.

Typical Applications

• Military and Aerospace Systems — Military-grade temperature range and packaging make the device suitable for high-reliability embedded control and interface functions in harsh environments.
• PCI-Based Interface and Peripheral Control — 66 MHz PCI compliance and extensive, configurable I/O support enable use as a bridge or controller for PCI peripheral subsystems.
• High-Reliability Embedded Logic — High gate count and deterministic timing support complex custom logic, signal processing control, and mission-critical state machines.

Unique Advantages

• High Gate Density: 108,000 system gates and 6,036 logic elements provide significant integration density to consolidate logic and reduce BOM.
• Flexible I/O Voltage Support: Configurable I/O standards and 5 V tolerance/drive capability simplify interfacing to legacy and mixed-voltage peripherals.
• Nonvolatile Single-Chip Configuration: Eliminates the need for external configuration memory, simplifying system design and improving boot determinism.
• Designed for Harsh Environments: Military grade rating and −55 °C to 125 °C operation support deployments where temperature extremes and reliability are critical.
• Security and Testability: FuseLock secure programming plus IEEE-1149.1 boundary-scan and in-system diagnostics improve IP protection and production test coverage.
• Deterministic Timing and Diagnostics: User-controllable timing and Silicon Explorer II capability help validate and debug designs in-system.
