LAV-AT-G70-1LFG1156C

The LAV-AT-G70-1LFG1156C is an Avant™-G Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor, built on the Avant platform architecture. It delivers high logic capacity and a large programmable I/O complement in a 1156-ball FCBGA package for surface-mount assembly.

Designed for commercial-temperature applications, this device is aimed at designs that require substantial on-chip logic, abundant I/O, integrated memory resources, and flexible clocking and interface capabilities as described in the Avant platform documentation.

Key Features

• Core Logic  637,000 logic element cells provide high user logic capacity for complex digital designs.
• Embedded Memory  Approximately 4.24 Mbits of total on-chip RAM, with sysMEM features such as single/dual/pseudo-dual port modes, FIFO support, and memory cascading described in the Avant platform overview.
• I/O Capacity  554 programmable I/O pins to support dense external connectivity requirements.
• Clocking and Timing  Comprehensive clocking architecture including on-chip oscillator, PLL, global and regional clocks, dynamic clock control, and clock synchronizers as documented for the Avant platform.
• High-Speed Interfaces  Platform-level support for SERDES/PMA blocks, multi-protocol PCS and PHY integration, and DDR memory PHY functionality as noted in the Avant platform documentation.
• Configuration and Diagnostics  Enhanced configuration options, JTAG support, SEU handling approaches, and trace ID capabilities are included in the platform overview.
• Package and Mounting  1156-ball FCBGA package (1156-FCBGA, 35×35) in a surface-mount form factor for board-level assembly.
• Electrical and Environmental  Supply voltage specified at 820 mV; commercial operating temperature range from 0 °C to 85 °C. RoHS compliant.
• Grade  Commercial grade device for mainstream embedded and communications designs.

Typical Applications

• High-density digital processing  Use the large logic fabric and embedded memory for compute- or control-intensive functions within commercial embedded systems.
• Interface bridging and protocol conversion  Leverage the extensive I/O count and platform SERDES/PCS capabilities to implement protocol translation and multi-interface hubs.
• Memory-centric logic  Take advantage of sysMEM features and DDR PHY support for designs that require on-chip buffering, FIFOs, and memory interfacing.

Unique Advantages

• High logic density: 637,000 logic elements enable large combinational and sequential designs without external logic.
• Substantial embedded memory: Approximately 4.24 Mbits of on-chip RAM with flexible operating modes (single/dual/pseudo-dual port, FIFO, cascading) for data buffering and state storage.
• Extensive I/O resources: 554 programmable I/Os support dense peripheral and interface requirements on a single device.
• Comprehensive clocking: On-chip oscillator, PLLs, and multiple clock domain options provide versatile timing and synchronization capabilities described in the Avant platform.
• Compact, serviceable package: 1156-FCBGA (35×35) surface-mount package balances high pin-count integration with board-level manufacturability.
• Platform-level features: Built on the Avant platform, offering documented support for SERDES, DDR PHY, sysDSP, and configuration/diagnostic mechanisms important for complex designs.
