• Performance — Datasheet-specified system performance up to 250 MHz and internal performance up to 350 MHz for timing-critical logic.
• Power and I/O Behavior — Hot-swap compliant I/Os and power-up/power-down friendly operation that does not require sequencing of supply voltages.
• Mixed-Voltage Operation — Supports 2.5 V, 3.3 V and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength.
• Package — 484-pin fine-pitch BGA (484-FPBGA, 27×27) in a surface-mount package suitable for compact board layouts.
• Supply & Temperature — Voltage supply range 2.25 V to 5.25 V; commercial operating temperature 0 °C to 70 °C.
• Built-in Test & Security — Boundary-scan testing (IEEE 1149.1/JTAG) and secure programming technology (FuseLock) as documented in the product datasheet.
• Regulatory — RoHS compliant.

Typical Applications

• PCI and Bus Interface Designs — Use the device’s PCI-compliant I/O configurations and high I/O count to implement bus bridging, protocol logic or system interface functions.
• I/O-Intensive Embedded Systems — High I/O density and mixed-voltage support make the device suitable for controllers and peripherals that require many external interfaces.
• High-Performance Logic and Control — With hundreds of MHz internal/system performance and abundant flip-flops, the FPGA is suitable for timing-critical control, signal steering, and processing glue logic in commercial products.
• In-System Diagnostics and Test — On-chip support for boundary-scan and the documented in-system diagnostic capabilities assist manufacturing test and field verification.

Unique Advantages

• Nonvolatile Single-Chip Solution: Eliminates external configuration memory for simpler system design and reliable startup behavior.
• High I/O Count with Mixed-Voltage Support: Enables integration of multiple voltage domains and diverse peripheral interfaces without additional level-shifting components.
• Deterministic Timing and High Internal Speed: System and internal performance figures support designs that require predictable, high-speed logic paths.
• Power-Up/Down Friendly I/Os: Simplifies board power sequencing and hot-swap scenarios by avoiding strict supply sequencing requirements.
• Secure Programming Capabilities: FuseLock secure programming reduces risk of reverse engineering and IP exposure as documented in the datasheet.
• Compact Fine-Pitch BGA Package: 484-FPBGA (27×27) allows high connector density in space-constrained commercial designs.
