LAV-AT-X50-1LFG676C

The LAV-AT-X50-1LFG676C is an Avant™-X Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor, supplied in a 676-FCBGA (27×27) package for surface-mount applications. It delivers a high-density programmable fabric with 409,000 logic elements, approximately 2.7 Mbits of embedded RAM, and 298 general-purpose I/O pins—targeted at complex embedded and communications designs that require high integration in a compact BGA footprint.

Built on the Lattice Avant platform, the device architecture provides a broad set of on-chip capabilities including programmable clocking, memory and DSP primitives, programmable I/O, and interfaces for DDR and serial links as described in the Avant platform documentation.

Key Features

• Logic Capacity — 409,000 logic element cells to implement large-scale digital functions and custom hardware accelerators.
• Embedded Memory — Approximately 2.7 Mbits of total on-chip RAM for buffering, FIFOs, and local storage with support for single/dual/pseudo-dual port modes described in the platform documentation.
• I/O Density — 298 I/O pins supporting a wide range of interfacing requirements in a single device.
• Package & Mounting — 676-BBGA / 676-FCBGA (27×27) package, surface-mount suitable for compact board designs.
• Voltage & Power — Core voltage specified at 0.820 V; device-level power characteristics are determined by design implementation.
• Operating Range & Grade — Commercial grade device rated for 0 °C to 85 °C operation and RoHS compliant.
• Platform Capabilities — Avant platform architecture includes programmable functional units, on-chip oscillator, PLLs, global and regional clocking, sysMEM memory blocks, sysDSP resources, programmable I/O cells, DDRPHY support, and SERDES/PCS building blocks as detailed in the Avant documentation.
• Configuration & Reliability — Device configuration and management features described in the platform reference include enhanced configuration options, JTAG access, and SEU handling approaches.

Typical Applications

• High-performance signal processing — Implement dense DSP pipelines and hardware accelerators using the large logic fabric and embedded sysDSP resources.
• Networking and communications — Support protocol processing, packet handling, and multi‑lane serial interfaces leveraging the platform's SERDES/PCS and high I/O count.
• Memory interface and buffering — Use on-chip sysMEM blocks and DDRPHY support for memory controllers, FIFOs, and high-throughput data staging.
• Compact embedded systems — Integrate control, glue logic, and peripheral interfaces into a single BGA package for space-constrained boards.

Unique Advantages

• High integration density: 409,000 logic elements and ~2.7 Mbits of embedded RAM reduce external components and simplify board-level designs.
• Extensive I/O connectivity: 298 I/O pins support diverse interfaces and multiple peripherals without external multiplexing.
• Compact BGA package: 676-FCBGA (27×27) enables a small PCB footprint while maintaining high pin count for system-level consolidation.
• Avant platform feature set: Built-in clock management, memory primitives, DSP blocks, DDRPHY and SERDES/PCS building blocks streamline implementation of complex applications.
• Commercial temperature and RoHS compliance: Rated 0 °C to 85 °C and RoHS-compliant for mainstream embedded and consumer products.
