A54SX32A-1FGG484

The A54SX32A-1FGG484 is a commercial-grade, nonvolatile SX-A family FPGA offered in a 484-ball fine-pitch BGA (27 × 27 mm) package. It provides 48,000 system gates and 2,880 logic elements with 249 user-programmable I/O pins, targeting mixed-voltage embedded designs that require a single-chip, configuration-retaining FPGA.

Designed for applications needing deterministic timing, configurable multi-voltage I/O and board-level testability, this device delivers family-level performance characteristics including up to 250 MHz system performance and up to 350 MHz internal performance as documented for the SX-A family.

Key Features

• Logic Capacity — 48,000 system gates and approximately 2,880 logic elements provide mid-range programmable logic density for glue logic, protocol bridging and control functions.
• I/O and Package — 249 user I/Os in a 484-FPBGA (27 × 27) package; surface-mount BGA form factor for compact board-level integration.
• Voltage and Mixed-Voltage Support — Device-level supply range 2.25 V to 5.25 V. SX-A family I/O supports 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 with 5 V input tolerance and 5 V drive capability for mixed-voltage system designs.
• Performance Characteristics — Family-level documented performance includes 250 MHz system performance and 350 MHz internal performance for timing-critical logic.
• Nonvolatile Single-Chip Solution — Nonvolatile architecture retains configuration without external configuration memory, simplifying board design and enabling instant-on behavior.
• System and Board-Level Features — Hot-swap compliant I/Os, power-up/power-down friendly operation (no sequencing required), boundary-scan testing (IEEE 1149.1) and in-system diagnostic/verification capability.
• Security and Reliability — Actel Secure Programming Technology (FuseLock™) to protect design IP and prevent reverse engineering.
• Control and I/O Options — Configurable weak pull-up/pull-down at power-up and individual output slew-rate control to help meet signal-integrity and system-power requirements.
• Environmental and Grade — Commercial grade with an operating temperature range of 0 °C to 70 °C and RoHS-compliant packaging.
• On-Chip Memory — No embedded RAM bits (Total RAM Bits: 0), enabling deterministic flip-flop-based implementations where on-chip RAM is not required.

Typical Applications

• PCI and Bus Interface Logic — 66 MHz PCI compliance and mixed-voltage I/O support make this device suitable for implementing bus bridges, interface logic and custom peripheral controllers.
• Mixed-Voltage System Glue — Configurable I/Os with 5 V tolerance and multi-voltage operation are ideal for level translation, protocol adaptation and board glue between 5 V and lower-voltage subsystems.
• Board-Level Test and Diagnostics — Boundary-scan (JTAG) and in-system diagnostic features support manufacturing test, board bring-up and field verification workflows.
• Secure IP Implementation — Built-in FuseLock programming protects sensitive logic and algorithms implemented in the FPGA.

Unique Advantages

• Nonvolatile, Single-Chip Configuration: Eliminates external configuration memory and simplifies power-up behavior and board design.
• Mixed-Voltage I/O Flexibility: Support for 2.5 V, 3.3 V and 5 V signaling with 5 V tolerance reduces the need for external level shifters in heterogeneous systems.
• Deterministic Timing and High Internal Performance: Documented system and internal performance figures enable predictable timing closure for control and interface logic.
• Production and Diagnostic Friendliness: Boundary-scan and in-system diagnostic capabilities streamline manufacturing test and field troubleshooting.
• IP Protection: FuseLock secure programming protects design confidentiality and reduces risk of reverse engineering.
• Compact BGA Packaging: 484-FPBGA footprint delivers high I/O count in a compact, surface-mount package suitable for dense PCB layouts.
