A54SX32A-FG256I

The A54SX32A-FG256I is an SX-A family FPGA in a 256-pin fine-pitch BGA package, offering a nonvolatile single-chip FPGA solution targeted at industrial applications. It provides 48,000 system gates and 2,880 logic elements with up to 203 user-programmable I/Os, making it suitable for embedded control, interface, and system-integration roles where mixed-voltage I/O and industrial temperature range support are required.

Designed for deterministic timing and in-system verification, the device combines configurable I/O flexibility and on-chip security features from the SX-A family to support robust, field-updatable FPGA designs.

Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements provide substantial programmable logic resources for mid-density designs.
• I/O and Package — 203 user I/Os in a 256-pin fine-pitch BGA (256-FPBGA, 17×17) package for compact board-level integration and high pin-count connectivity.
• Performance (SX-A family) — Series-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance (SX-A family data).
• Voltage and Mixed-Voltage I/O — Supply range 2.25 V to 5.25 V with configurable I/O support for multiple signaling levels and 5 V input tolerance (SX-A family characteristics).
• Industrial Temperature Grade — Rated for operation from −40 °C to 85 °C to meet industrial environment requirements.
• Nonvolatile Single-Chip Solution — SX-A family nonvolatile architecture provides single-chip configuration retention and system-level power-up behavior that does not require supply sequencing.
• I/O and System Control Features — Hot-swap compatible I/Os, configurable weak pull-up/pull-down on power-up, and individual output slew rate control (SX-A family).
• System Test and Security — Boundary-scan (IEEE 1149.1) support and Actel Secure Programming Technology with FuseLock for anti-tamper and reverse-engineering protection (SX-A family).
• RoHS Compliant — Device is RoHS compliant.
• On-Chip Memory — Total on-chip RAM bits: 0 (no dedicated embedded RAM).

Typical Applications

• Industrial Control — Use as a programmable logic core for machine control, I/O aggregation, and deterministic timing tasks in industrial systems operating across −40 °C to 85 °C.
• Interface and Bridge Functions — Implement mixed-voltage interface logic and protocol bridging where 203 I/Os and configurable I/O standards are required.
• PCI-Compatible Subsystems — Suitable for subsystem logic in designs that require 66 MHz PCI compliance capabilities (SX-A family feature).
• In-System Diagnostics and Verification — Deploy for systems that benefit from in-system diagnostic capability and boundary-scan testability to simplify validation and service.

Unique Advantages

• Deterministic, User-Controllable Timing: SX-A family timing architecture supports predictable timing closure for time-critical designs.
• Nonvolatile, Single-Chip Configuration: Eliminates external configuration memory and simplifies board-level design and power sequencing.
• Mixed-Voltage I/O with 5 V Tolerance: Broad supply range and configurable I/O options reduce level-shifting components and simplify mixed-voltage system integration.
• Industrial Temperature Qualified: −40 °C to 85 °C rating aligns the device with industrial deployment and harsh-environment operation.
• On-Chip Security Features: FuseLock-based secure programming helps protect intellectual property and prevent reverse engineering (SX-A family).
• Boundary-Scan Testability: IEEE 1149.1-compliant JTAG support enables standardized board-level test and diagnostics.
