A54SX72A-FG256M

The A54SX72A-FG256M is a military-grade member of the SX-A family of nonvolatile FPGAs. It provides a high-density programmable fabric—6,036 logic elements and 108,000 system gates—along with 203 user I/O pins in a 256-ball fine-pitch BGA package, designed for applications that require robust thermal and voltage margins.

Targeted at high-reliability systems, this device combines deterministic timing, secure in-system programming, and wide voltage and temperature support to address military and other mission-critical embedded designs.

Key Features

• Logic Capacity — 6,036 logic elements (combinatorial resources) delivering 108,000 system gates for complex logic and control functions.
• Programmable Registers — Up to 2,012 dedicated flip-flops available for state and pipeline designs.
• User I/O — 203 user-programmable I/O pins suitable for dense interfacing and board-level integration.
• Performance — SX-A family performance points listed at 250 MHz system performance and 350 MHz internal performance options for timing-sensitive logic.
• Nonvolatile Single-Chip Architecture — Single-chip nonvolatile FPGA eliminates the need for external configuration memory and supports in-system reprogramming.
• I/O Flexibility and PCI Support — Configurable I/O supporting 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2. Devices in the family are 66 MHz PCI compliant and support mixed-voltage operation with 5 V input tolerance and drive strength options.
• Power and Reliability — Power-up/power-down friendly design that does not require supply sequencing; hot-swap compliant I/Os aid reliability in live-insert systems.
• Security and Testability — Actel Secure Programming technology with FuseLock™ for protection against reverse engineering, plus IEEE 1149.1 (JTAG) boundary-scan testing for board-level verification.
• Package and Mounting — 256-ball fine-pitch BGA (256-FPBGA, 17×17) in a surface-mount package targeted at compact, high-density board layouts.
• Voltage and Temperature Range — Operates from 2.25 V to 5.25 V and specified for military temperature grade (−55 °C to 125 °C).
• Standards and Diagnostics — Deterministic, user-controllable timing and in-system diagnostic/verification capability with Silicon Explorer II (SX-A family feature).
• RoHS Compliance — Device is RoHS compliant.

Typical Applications

• Military and Aerospace Systems — Military temperature grade and wide voltage range make the device suitable for avionics, ruggedized communications, and other defense applications requiring high reliability.
• PCI-Based Embedded Systems — 66 MHz PCI compliance and configurable I/O levels enable use as interface logic, glue, or protocol support in PCI-based boards.
• High-Reliability Control and Signal Processing — Large logic capacity and a sizable register pool support complex control algorithms and deterministic timing for mission-critical processing.
• Board-Level Test and Security — Boundary-scan support and FuseLock programming add value for production testability and IP protection on sensitive designs.

Unique Advantages

• High-density programmable fabric: 6,036 logic elements and 108,000 system gates provide substantial on-chip logic for complex designs while minimizing external glue logic.
• Wide operating envelope: 2.25 V to 5.25 V supply range and −55 °C to 125 °C temperature rating support demanding electrical and thermal environments.
• Nonvolatile single-chip solution: Eliminates external configuration memory and simplifies system startup and reliability management.
• Flexible mixed-voltage I/O: Supports multiple I/O standards and 5 V tolerant inputs to ease integration with legacy and modern subsystems.
• Built-in security and test: FuseLock programming plus IEEE 1149.1 JTAG boundary-scan facilitate IP protection and manufacturing test flow.
• Designed for deployable systems: Hot-swap compliant I/Os and power-up/power-down friendliness reduce system-level power sequencing constraints.
