• Flexible Memory Architecture (Family)  The family supports embedded block RAM (EBR) and distributed RAM options, including 18Kbit EBR blocks and multiple port modes for system buffering and packet processing.
• Clocking and System Integration (Family)  Multiple PLLs and DLLs in the family provide clock multiply/divide and phase/delay adjustments for timing-critical designs.
• Programmable I/O Standards (Family)  Family support for a broad range of I/O standards (LVTTL, LVCMOS, SSTL, HSTL, LVDS, LVPECL and others) enables interface flexibility across protocols and memory interfaces.
• Configuration and Security (Family)  Flexible configuration options include SPI boot, dual-boot image support and optional bitstream encryption on "S" family variants.

Typical Applications

• Telecommunications & Networking  Mid-range packet processing, aggregation and protocol bridging leveraging the family’s SERDES and high I/O capability.
• High-Speed Serial Interfaces  PHY/PCS and chip-to-chip serial links that benefit from the family’s embedded SERDES and equalization/pre-emphasis features.
• Signal Processing & DSP  Implement filtering, FFTs and other DSP functions using the family’s dedicated sysDSP blocks and embedded memory.
• Memory Interfaces and Buffering  DDR and source-synchronous interface support for systems requiring dedicated DQS and DDR gearing logic.
• System Integration & Prototyping  Combine logic, memory and I/O on a single device to reduce BOM count and accelerate time-to-market for embedded systems.

Unique Advantages

• Balanced Logic and Memory: The combination of ~19,000 logic elements and ~1.246 Mbits of embedded RAM supports complex control and data-path designs without external logic proliferation.
• High I/O Density in a Compact Package: 304 I/Os in a 484-FPBGA (23 × 23 mm) enable dense pinouts suitable for multi-channel interfaces and mezzanine-style connections.
• Family-Level High-Speed SerDes and DSP: Access to SERDES and sysDSP capabilities in the ECP2M family enables scalable serial connectivity and efficient arithmetic processing.
• Flexible I/O Standards: Broad programmable I/O options simplify interfacing to a wide range of memory devices, transceivers and logic levels.
• Comprehensive Clocking and Configuration: On-chip PLL/DLL resources and flexible boot/configuration options streamline system-level design and update flows.
• Vendor Ecosystem Support: Family support via Lattice design tools helps accelerate implementation and debugging for medium-complexity FPGA projects.
