• Drive Capability — Output sink and source capability of 4 mA for typical I/O loading scenarios (series specification).
• Supply and Mounting — Operates from 4.75 V to 5.25 V; surface-mount device for PCB assembly.
• Package — 100-BQFP package (supplier device package: 100-PQFP, 20 × 14 mm) for compact board-level integration.
• Commercial Grade & Temperature Range — Commercial grade device with an operating temperature range of 0 °C to 85 °C.
• Standards Compliance — RoHS compliant.
• Compatibility — XC3000 family bitstreams are upward compatible with XC3000A and are 100% bitstream compatible with the XC3100 family (series specification).

Typical Applications

• General Logic Replacement: Replace discrete logic networks and glue logic in board-level designs with a single programmable device.
• Sub-system Integration: Consolidate multiple small functions into a compact FPGA to simplify PCB layout and reduce BOM count.
• I/O-Rich Interfaces: Use the 82 user I/Os for peripheral bridging, sensor interfacing, and protocol adaptation in embedded systems.

Unique Advantages

• Programmable Flexibility: Reprogram the device to iterate hardware functionality during development and field updates, reducing time-to-market for evolving designs.
• Predictable Performance: Series-level guaranteed toggle rates and documented logic delays help you estimate timing performance during design planning.
• On-Chip Memory: 30,784 bits of embedded RAM provide local buffering for control logic and small data paths, minimizing external memory requirements.
• Low-Power Options: Advanced CMOS technology and a power-down ultra-low current option reduce standby and active power for power-sensitive designs.
• Standard 5 V Support: Compatibility with 5 V systems simplifies integration into existing board-level power architectures.
• Compact Packaging: 100-pin BQFP surface-mount package enables dense PCB integration while preserving a broad set of I/Os.
