Key Features

• Logic Capacity — 12,000 system gates and 768 logic elements provide the core resources to implement combinational and sequential logic for a variety of mid-range designs.
• User I/O — 81 user-programmable I/Os available in the 100-pin package allow interfacing to sensors, peripherals, and external buses.
• Nonvolatile Single-Chip Architecture — Built-in nonvolatile configuration removes the need for an external configuration memory, simplifying board-level design.
• Performance — Family-level performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• Flexible I/O and Mixed-Voltage Support — Configurable I/O support and mixed-voltage operation (2.25 V to 5.25 V supply range) with 5 V input tolerance enable direct interfacing with common logic families and PCI signals.
• Package — 100-pin thin quad flat pack (TQFP) / 100-LQFP form factor (14 × 14 mm) for straightforward surface-mount assembly and compact PCB integration.
• Power and Reliability — Power-up/down friendly I/Os with configurable weak pull-up/pull-down options and individual output slew-rate control for signal integrity management.
• Security and Test — Family features include Secure Programming Technology (FuseLock™) to protect bitstreams and IEEE 1149.1 JTAG boundary-scan support for board-level testing and diagnostics.
• Environmental Compliance — RoHS-compliant device suitable for commercial product builds.
• Operating Range — Commercial temperature grade with an operating temperature range of 0 °C to 70 °C.

Typical Applications

• Embedded Control — Implements custom control logic, sequencing, and peripheral interfacing in compact embedded systems where nonvolatile configuration is preferred.
• Consumer Electronics — Provides programmable glue logic, protocol adaptation, and interface bridging in consumer devices with mixed-voltage I/O requirements.
• Prototyping and Development — Useful for hardware validation and firmware development where in-system programmability and diagnostic visibility are needed.
• PCI-Compatible Interfaces — Supports designs requiring 66 MHz PCI-compliant signaling and related interface logic through configurable I/O options.

Unique Advantages

• Nonvolatile, single-chip solution: Eliminates external configuration memory and simplifies BOM and board routing.
• Mixed-voltage flexibility: Wide supply range (2.25 V to 5.25 V) and configurable I/O allow direct interfacing to multiple logic families without extra level shifting.
• Compact package with ample I/O: 100-pin TQFP/LQFP balances small footprint with 81 user I/Os for dense, space-constrained designs.
• Built-in security and testability: FuseLock programming protection and IEEE 1149.1 boundary-scan support enhance IP protection and manufacturing test coverage.
• Deterministic timing and performance: Family-level timing and internal performance characteristics enable predictable timing closure for critical paths.
• RoHS-compliant commercial device: Meets common environmental requirements for consumer and commercial products.
