A54SX72A-FG484M

The A54SX72A-FG484M is a military-grade SX-A family Field Programmable Gate Array (FPGA) offered by Microchip Technology. This nonvolatile, single-chip FPGA delivers high logic capacity and dense I/O for applications that require secure, in-system programmability and robust operation across a wide temperature range.

Designed for systems needing high I/O count, deterministic timing and secure programming, the device targets mission-critical and rugged electronic designs where long-term reliability and configurability are essential.

Key Features

• Logic Capacity — 108,000 system gates and approximately 6,036 logic elements (combinatorial cells) provide substantial on-chip programmable logic resources.
• I/O and Interfaces — Up to 360 user-programmable I/O pins with configurable support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling. I/Os are hot-swap compliant and offer configurable weak pull-up or pull-down at power-up.
• Performance — Datasheet-specified system performance up to 250 MHz and internal performance up to 350 MHz, with deterministic, user-controllable timing for predictable system behaviour.
• Power and Voltage Flexibility — Operates from 2.25 V to 5.25 V and provides 5 V input tolerance with 5 V drive strength where supported, enabling mixed-voltage designs.
• Package and Mechanical — 484-FPBGA package (27×27 mm) providing a fine-pitch BGA footprint and high pin density for compact board designs.
• Temperature and Grade — Military-grade device rated for operation from −55 °C to 125 °C for deployment in demanding thermal environments.
• Security and Configuration — Nonvolatile single-chip configuration with Actel Secure Programming Technology (FuseLock™) to help protect design IP and prevent reverse engineering.
• Diagnostics and Testability — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability using Silicon Explorer II.
• System-Friendly Features — Power-up/power-down friendly operation (no sequencing required for supply voltages), individual output slew-rate control, and support for up to 100% resource utilization and 100% pin locking.
• RoHS Compliance — Device is RoHS compliant for restricted substance requirements.
• On-chip Memory — No embedded RAM bits (Total RAM Bits: 0), enabling predictable logic-only implementations where on-chip RAM is not required.

Typical Applications

• PCI-based Systems — Supports 66 MHz PCI and configurable I/O voltages for mixed-voltage PCI interfaces and legacy bus integration.
• Military and Rugged Electronics — Military grade temperature range (−55 °C to 125 °C) and robust package options for deployment in rugged and defense applications.
• High-Density I/O Control — Up to 360 user I/Os suit board-level interface consolidation, signal routing and glue-logic replacement in complex systems.
• Secure, In-System Programmable Designs — Nonvolatile configuration with FuseLock™ and in-system diagnostics for secure field updates and verification.

Unique Advantages

• High integration density: 108,000 system gates and ~6,036 logic elements reduce the need for external glue logic and simplify high-complexity designs.
• Wide voltage flexibility: 2.25–5.25 V operating range and 5 V input tolerance support mixed-voltage systems and simplify power-rail design.
• Rugged temperature performance: Military temperature grade and BGA packaging enable reliable operation in harsh thermal environments.
• Secure, nonvolatile configuration: FuseLock™ technology and single-chip nonvolatile operation protect intellectual property and eliminate external configuration memory.
• System-friendly I/O and power behavior: Hot-swap compliant I/Os, power-up/power-down friendly operation, and individual output slew control ease integration into complex systems.
• Deterministic timing and testability: User-controllable timing plus IEEE 1149.1 boundary-scan support enable predictable performance and streamlined manufacturing test.
