A54SX32A-FFG256

The A54SX32A-FFG256 is an SX-A family nonvolatile FPGA offered in a 256-ball fine-pitch BGA (17 × 17) surface-mount package. It provides 48,000 system gates with 2,880 logic elements and up to 2,012 dedicated flip-flops, delivering a compact, reprogrammable logic solution for designs that require configurable I/O and deterministic timing.

Built for mixed-voltage systems, the device supports a broad supply range and configurable I/O standards, and offers family-level features such as hot-swap compliant I/Os, power-up/power-down friendly operation, on-chip security programming, and boundary-scan support.

Key Features

• Core Capacity  48,000 system gates with 2,880 logic elements and up to 2,012 dedicated flip-flops for mid-range logic and control functions.
• High I/O Density  203 user-programmable I/O pins in the 256-ball FBGA package to support complex interfacing and multiple peripheral connections.
• Performance  Family-level performance targets include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Mixed-Voltage I/O  Configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2, with 5 V input tolerance and selectable drive strengths for flexible board-level interfacing.
• Power and Supply  Operates across a wide supply range (2.25 V to 5.25 V) and is power-up/power-down friendly with no sequencing required for supply voltages.
• Packaging  256-ball fine-pitch BGA (supplier package 256-FPBGA, 17 × 17) — surface-mount package suitable for compact PCBs.
• Security and Testability  Actel Secure Programming Technology with FuseLock™ to protect programmed designs, and IEEE 1149.1 boundary-scan (JTAG) support for board-level test.
• System Features  Hot-swap compliant I/Os and configurable weak pull-up/pull-down options at power-up; deterministic, user-controllable timing and in-system diagnostic capability via Silicon Explorer II (family feature).
• Compliance and Grade  Commercial temperature grade (0 °C to 70 °C) and RoHS compliant.

Typical Applications

• Mixed-voltage interface control  Use the A54SX32A-FFG256 to bridge and manage interfaces across 2.5 V, 3.3 V and 5 V domains while maintaining 5 V input tolerance.
• PCI and bus logic  Leverage the device’s PCI-compliant I/O options and deterministic timing to implement PCI glue logic, bus adapters, or interface controllers.
• Glue logic and peripheral control  Deploy the FPGA as customizable glue logic to consolidate discrete components and simplify PCB routing for embedded systems.
• In-system diagnostics and verification  Use the family’s in-system diagnostic capabilities for verification and debug during development and production bring-up.

Unique Advantages

• Highly configurable I/O:  Supports multiple I/O standards and selectable drive strengths to minimize external level-shifters and simplify board design.
• Nonvolatile single-chip solution:  SX-A family nonvolatile architecture removes the need for external configuration memory, simplifying system startup and security.
• Security-focused programming:  FuseLock™ secure programming protects IP and helps prevent reverse engineering of programmed designs.
• Deterministic timing control:  User-controllable timing resources help achieve predictable timing closure for control and interface logic.
• Compact high-density package:  256-ball FBGA (17 × 17) delivers 203 I/Os in a surface-mount footprint for space-constrained PCBs.
• Board-level test and debug readiness:  IEEE 1149.1 boundary-scan support and family diagnostic tools improve test coverage and accelerate debug.
