LAV-AT-G30-2LFG676C

The LAV-AT-G30-2LFG676C is an Avant™-G Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor, delivered in a 676‑BBGA FCBGA (27×27) surface-mount package. It implements the Avant platform architecture and provides a high-density fabric with on-chip memory and a comprehensive clocking and I/O infrastructure.

Key platform capabilities include programmable functional unit (PFU) blocks, dedicated sysMEM and sysDSP resources, and multi-domain clocking elements such as on‑chip oscillators and PLLs. These capabilities support designs that require substantial logic capacity, embedded memory, and flexible high‑speed I/O.)

Key Features

• Logic Capacity — 262,000 logic elements suitable for complex programmable logic implementations and custom hardware acceleration.
• Embedded Memory — Total on-chip RAM of 1,740,800 bits (approximately 1.74 Mbits) for data buffering, state storage, and memory-mapped logic.
• I/O Resources — 298 I/O pins with a programmable I/O cell (PIC) architecture and sysI/O banking to support multiple interface standards and flexible pin banking.
• Clocking and Timing — Avant platform clock architecture including on‑chip oscillator, PLL, global and regional clocks, dynamic clock select and control, and DLL delay elements for precise timing management.
• Memory Subsystem (sysMEM) — Features documented in the Avant platform such as bus size matching, RAM initialization/ROM operation, memory cascading, single/dual/pseudo-dual port modes, and FIFO modes.
• DSP and Processing — Dedicated sysDSP resources integrated into the Avant architecture for arithmetic and signal-processing functions.
• High‑Speed Interfaces — Platform-level SERDES/PMA and PCS blocks with multi-protocol PHY integration and DDRPHY support for DDR memory interfaces (as described in the Avant platform overview).
• Package and Mounting — 676‑FCBGA (27×27) package, surface-mount for compact board integration.
• Electrical and Environmental — Voltage supply specified as 820 mV to 820 mV; commercial-grade operating temperature range 0 °C to 85 °C; RoHS compliant.

Typical Applications

• Memory Interface and Acceleration — Leveraging sysMEM features and DDRPHY support to implement memory controllers, buffers, and memory-centric accelerators.
• High‑Speed Serial Connectivity — Utilizing SERDES/PMA and PCS blocks for multi-protocol serial links and PHY integration in communication and networking endpoints.
• Signal Processing and Compute Offload — Employing sysDSP and abundant logic elements for DSP kernels, hardware accelerators, and real‑time processing tasks.

Unique Advantages

• Substantial Logic Density: 262,000 logic elements enable complex designs and integration of multiple functions into a single device, reducing board-level component count.
• Integrated Memory Resources: Approximately 1.74 Mbits of embedded RAM (sysMEM) supports local data storage, FIFO implementations, and memory cascades for larger buffering needs.
• Comprehensive Clocking Suite: On‑chip oscillator, PLLs, global/regional clocks, and dynamic clock controls help designers implement precise, multi-domain timing strategies.
• Flexible I/O and PHY Support: 298 I/O and platform SERDES/DDR capabilities allow adaptation to diverse interface requirements without extensive external logic.
• Compact Package: The 676‑FCBGA (27×27) surface-mount package offers high integration density for space-constrained designs.
