Key Features

• Logic Capacity  48,000 system gates and 2,880 logic elements provide substantial programmable logic resources for mid-density designs.
• I/O Density and Flexibility  174 user I/Os with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling; includes 5 V input tolerance and 5 V drive strength as described in the device family documentation.
• Performance  Device family performance targets include up to 250 MHz system performance and up to 350 MHz internal performance as specified in the datasheet.
• Nonvolatile, Single‑Chip Solution  On-chip nonvolatile configuration provides standalone operation without external configuration memory.
• System and Board-Level Compatibility  Features such as hot-swap compliant I/Os, power-up/power-down friendly behavior (no sequencing required for supply voltages) and 66 MHz PCI compliance support common industrial and board‑level use cases.
• Design Security and Testability  Includes boundary-scan testing (IEEE 1149.1) and secure programming technology to help protect intellectual property and enable in-system diagnostics.
• Package and Mounting  208-BFQFP package (supplier device package: 208-PQFP, 28×28) in a surface-mount form factor suited for standard PCB assembly.
• Industrial Temperature Range  Rated for operation from −40 °C to 85 °C to meet industrial temperature requirements.
• Supply Voltage  Operates across a wide supply range of 3 V to 5.5 V to support mixed-voltage system designs.
• Compliance  RoHS compliant.

Typical Applications

• Industrial Control  Programmable logic for motor control, machine I/O aggregation and custom control functions within −40 °C to 85 °C environments.
• PCI and Interface Cards  Supports 66 MHz PCI-compliant designs and mixed-voltage interface requirements for mezzanine and add-in cards.
• In-System Verification and Test  Boundary-scan (JTAG) support and in-system diagnostic capabilities simplify board bring-up and manufacturing test flows.
• Secure Embedded Systems  Nonvolatile configuration and secure programming features help protect firmware and design IP in deployed systems.

Unique Advantages

• Balanced Logic Density:  48,000 system gates with 2,880 logic elements provides ample resources for mid-range FPGA tasks without excessive board-level complexity.
• Flexible I/O with Voltage Tolerance:  Configurable I/O standards and 5 V tolerance reduce level-shifting needs and simplify interfacing to legacy and mixed-voltage peripherals.
• Nonvolatile Single‑Chip Configuration:  Eliminates the need for external configuration memory, reducing BOM and simplifying power-up behavior.
• Industrial-Ready Thermal Range:  Rated for −40 °C to 85 °C to support a wide set of industrial deployment scenarios.
• Testability and IP Protection:  JTAG boundary-scan and secure programming technology aid manufacturing test and protect design assets.
• Standards-Focused Integration:  Features such as hot-swap I/Os and PCI compliance align with common board- and system-level requirements.
