Key Features

• Logic Capacity — 24,000 system gates and approximately 1,452 logic elements provide mid-range programmable logic resources for glue-logic, protocol handling and control functions.
• I/O and Voltage Flexibility — 81 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. Device supports 5 V input tolerance and 5 V drive strength where applicable.
• Nonvolatile, Single-Chip Solution — Nonvolatile configuration preserves design state without external configuration memory and enables straightforward power-up behavior.
• Performance — System performance up to 250 MHz and internal paths up to 350 MHz enable high-speed signal and control processing where required by the design.
• Power and I/O Robustness — Hot-swap compliant I/Os and power-up/power-down friendly operation (no supply sequencing required) simplify integration into systems with complex power domains.
• Deterministic Timing & Diagnostics — Deterministic, user-controllable timing plus in-system diagnostic and verification capability provide predictable performance and on-board testability.
• Security and Test — Secure programming with FuseLock™ technology to help protect design IP, and boundary-scan testing compliant with IEEE 1149.1 (JTAG) for board-level testability.
• Package & Mounting — 100-pin TQFP (thin quad flat pack) surface-mount package, supplier device package 100-VQFP (14×14).
• Industrial Temperature Grade — Rated for operation from −40 °C to +85 °C for industrial environments.
• Wide Supply Range — Supports a supply voltage range from 3.0 V to 5.5 V to accommodate mixed-voltage system designs.
• RoHS Compliant — Meets RoHS requirements.
• Embedded Memory — No embedded RAM (0 bits), suitable for applications where RAM is not required on-chip.

Typical Applications

• Industrial Control — Implement deterministic control logic, protocol translation and I/O bridging for factory automation and process control systems within industrial temperature ranges.
• Interface and Peripheral Bridging — Provide mixed-voltage interface support and PCI-compliant signaling for peripheral controllers, bus bridges and I/O expansion modules.
• Embedded System Glue Logic — Replace discrete logic with compact, reprogrammable logic for timing control, address decoding and custom bus interfaces.
• Test & Measurement — Use deterministic timing and boundary-scan support for instrumentation, data acquisition front-ends, and in-system verification flows.

Unique Advantages

• Secure, Nonvolatile Configuration: Single-chip nonvolatile FPGA with FuseLock™ programming reduces BOM complexity and helps protect IP without external configuration memory.
• Mixed-Voltage I/O Capability: Configurable I/O standards and 5 V tolerance simplify integration with a wide range of legacy and modern interfaces.
• Industrial Ready: Industrial temperature rating (−40 °C to +85 °C) and robust power-up behavior make the device suitable for demanding embedded environments.
• High-Speed Internal Paths: Up to 250 MHz system and 350 MHz internal performance enable fast control loops and timing-critical processing.
• Board-Level Test and Diagnostics: JTAG boundary-scan and in-system diagnostic tools provide easier manufacturing test and field verification.
• Compact, Surface-Mount Package: 100-pin TQFP package supports higher-density board layouts while maintaining accessible I/O count.
