• Embedded Memory — Approximately 55,296 bits of on-chip RAM for buffering, FIFOs, or small data stores close to logic.
• I/O Capacity — 151 user I/O pins to support multiple parallel interfaces, sensor links, and peripheral connections.
• Power — Operates from a core supply range of 1.425 V to 1.575 V for low-voltage system integration.
• Package & Mounting — 208-BFQFP package (supplier package: 208-PQFP, 28 × 28 mm) in a surface-mount form factor for compact PCB layouts.
• Operating Range — Commercial-grade ambient temperature range from 0 °C to 85 °C suitable for standard commercial environments.
• Compliance — RoHS-compliant construction to support environmentally mindful manufacturing.
• Family Technology — Part of the ProASIC3 family of flash-based, low-power FPGAs (family-level features include low-power flash architecture and Flash*Freeze technology as documented in the ProASIC3 series datasheet).

Typical Applications

• Embedded Control — Implement machine control, protocol handling, or custom timing logic using the device’s 9,216 logic elements and 151 I/Os.
• Interface Bridging — Bridge or adapt between parallel and serial interfaces where moderate on-chip RAM and abundant I/O are required.
• Data Path Acceleration — Offload custom combinational and sequential logic to the FPGA fabric to accelerate application-specific data processing.
• Prototyping and Custom Logic — Compact 208-BFQFP package and surface-mount mounting make the device suitable for board-level prototypes and production designs that require reprogrammable logic.

Unique Advantages

• Balanced Logic Density: 9,216 logic elements and a 400,000-gate equivalent provide a balance of capacity for mid-range custom logic without excessive footprint.
• Significant On-Chip Memory: Approximately 55,296 bits of embedded RAM enable local data buffering and reduce external memory requirements for many control and interface tasks.
• High I/O Count: 151 I/O pins allow flexible connectivity for multi-channel interfaces and mixed-signal front-ends.
• Compact Surface-Mount Package: The 208-BFQFP (28 × 28 mm supplier PQFP) supports dense PCB layouts while maintaining serviceable pin access.
• Low-Voltage Core: A defined core supply range of 1.425 V to 1.575 V facilitates integration into modern low-voltage power domains.
• RoHS Compliance: Environmentally compliant manufacturing readiness helps meet regulatory and procurement requirements.
