• Memory and Timing Resources: Family features include multiple embedded memory blocks and up to ten PLLs per device (per datasheet) to support clocking and system timing requirements.
• Power Supply: Core voltage supply specified from 1.14 V to 1.26 V (device requires appropriate 1.2 V-class core supply).
• Industrial Grade and Temperature Range: Rated operating temperature from -40 °C to 100 °C for deployment in industrial environments.
• Package and Assembly: Surface-mount 484-FPBGA package (supplier device package: 484-FPBGA 23 × 23 mm) for compact PCB integration.
• Standards and Tools (Family-level): ECP3 family supports configuration utilities and tools referenced in the datasheet, such as ORCAstra configuration and Reveal logic analysis support.
• Environmental Compliance: RoHS compliant.

Typical Applications

• High‑speed serial communications: Implement PCIe, Ethernet, SONET/SDH or other serial protocols using the family’s embedded SERDES and high-speed I/O.
• Video and broadcast interfaces: Process and route SMPTE 3G and other video data streams leveraging the device’s DSP resources and high-speed I/O.
• Industrial networking and control: Use the 295 I/Os and industrial temperature rating for industrial automation, protocol bridging, and sensor aggregation.
• Embedded DSP processing: Offload signal processing tasks to sysDSP slices and on-chip RAM for real‑time filtering, aggregation or analytics.
• Memory interface and buffering: Implement DDR/DDR2/DDR3 interfaces and on-chip buffering using dedicated memory resources and source-synchronous I/O support described in the family datasheet.

Unique Advantages

• Well-balanced mid-range resources: 67,000 logic elements and ~4.53 Mbits of on-chip RAM provide ample capacity for complex mid-scale designs without excessive board area.
• High I/O and SERDES capability: 295 I/Os and the ECP3 family’s up-to-3.2 Gbps SERDES support enable robust connectivity for multi-protocol systems.
• Industrial temperature rating: Rated for -40 °C to 100 °C to meet environmental demands in factory and infrastructure deployments.
• Compact BGA package: 484-ball FPBGA (23 × 23 mm) delivers high pin count in a small footprint for space-constrained applications.
• Integrated system resources: On-chip RAM, PLLs/DLLs and DSP slices from the ECP3 family reduce external component count and simplify board design.
• Regulatory and environmental compliance: RoHS-compliant manufacturing helps streamline regulatory acceptance and disposal considerations.
