A54SX32A-FGG256I

The A54SX32A-FGG256I is a nonvolatile SX-A family FPGA offered in a 256-ball fine-pitch BGA package. It provides 48,000 system gates and 2,880 logic elements with up to 203 user I/O pins, and supports mixed-voltage operation across a wide supply range.

Designed for industrial-temperature applications, this single-chip FPGA combines configurable I/O flexibility, in-system diagnostics and secure programming features to address mixed-voltage, PCI-capable designs requiring deterministic timing and nonvolatile configuration.

Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements providing mid-range logic density for control, interface and glue-logic implementations.
• I/O Count & Flexibility — 203 user 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; configurable weak pull-up or pull-down at power-up.
• Mixed-Voltage Operation — Operates across a wide supply range from 2.25 V to 5.25 V with 5 V input tolerance and 5 V drive strength where applicable.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for time-critical logic paths.
• Nonvolatile, Single-Chip Solution — Built-in nonvolatile configuration removes the need for external configuration memory and enables instant-on behavior after power-up.
• Power-Up/Down Friendly — No supply sequencing required for power-up or power-down, simplifying multi-rail system designs.
• System Reliability & Test — Boundary-scan (IEEE 1149.1 JTAG) support and unique in-system diagnostic and verification capability for board-level testing and debug.
• Security — Secure programming technology with FuseLock™ prevents reverse engineering and protects design IP.
• Package & Temperature — 256-ball FBGA (256-FPBGA, 17×17) package in an industrial temperature grade with an operating range of −40 °C to 85 °C.

Typical Applications

• PCI and bus interface peripherals — 66 MHz PCI compliance and configurable 3.3 V/5 V PCI I/O support make this device suited for PCI-based interface logic and peripheral controllers.
• Mixed-voltage system glue logic — Wide supply voltage range and multi-standard I/O support simplify integration between 5 V legacy logic and modern lower-voltage rails.
• Industrial control and automation — Industrial temperature grade and deterministic timing support control systems, I/O aggregation and sensor/interface processing in industrial environments.
• In-system test and verification — Boundary-scan and on-chip diagnostic capabilities streamline board bring-up, testing and field diagnostics.

Unique Advantages

• Single-chip nonvolatile configuration: Eliminates external configuration memory and simplifies system boot behavior.
• Flexible mixed-voltage I/O: Broad I/O standard support and 5 V tolerance reduce the need for level-shifting components.
• Industrial temperature rating: Rated for −40 °C to 85 °C operation to meet extended-environment requirements.
• Secure programming and diagnostics: FuseLock™ security and in-system diagnostic features protect IP and aid in validation and field troubleshooting.
• Robust packaging: 256-ball FBGA (17×17) delivers a compact footprint with high I/O count for space-constrained boards.
• Deterministic timing and performance: Family-level device performance supports time-sensitive logic with predictable behavior for embedded designs.
