LAV-AT-E70-1LFG676C

The LAV-AT-E70-1LFG676C is an Avant™-E FPGA IC from Lattice Semiconductor Corporation built on the Lattice Avant platform. It provides high-density programmable logic, a substantial pool of embedded RAM, and a large I/O count in a compact 676-FCBGA (27×27) surface-mount package.

Targeted for commercial applications, this device combines approximately 477,000 logic elements, roughly 4.24 Mbits of on-chip RAM, and 312 I/Os to support complex custom logic, memory buffering, and multi-protocol I/O requirements while operating from a nominal 820 mV supply across a 0 °C to 85 °C temperature range.

Key Features

• Core Logic Capacity Approximately 477,000 logic elements provide high-density programmable resources for complex logic and hardware acceleration tasks.
• Embedded Memory Approximately 4.24 Mbits of total on-chip RAM to support FIFOs, buffers, and local data storage for state machines and accelerators.
• I/O Count and Flexibility 312 I/Os delivered from programmable I/O banks suitable for broad interfacing needs and system-level integration.
• Platform Architecture Based on the Lattice Avant platform with architecture topics covered in the product documentation including PFU (programmable functional units), routing, clocking structures, sysMEM and sysDSP blocks, Programmable I/O, DDR memory support, SerDes/PCS, and system configuration options.
• Configuration and System Reliability Platform documentation references device configuration options, JTAG support, single event upset (SEU) handling, and trace/ID features to aid system integration and maintainability.
• Package and Mounting 676-FCBGA (27×27) package in a surface-mount form factor for compact board designs and high-density layouts.
• Power and Operating Range Device supply specified at 820 mV and rated for commercial-grade operation from 0 °C to 85 °C. RoHS compliant.

Typical Applications

• Communications and Networking Platform-level SerDes/PCS and high I/O count enable protocol bridging, packet processing, and interface adaptation in networking equipment.
• Memory Interface and Buffering Integrated sysMEM and DDR support make the device suitable for designs requiring high-bandwidth memory buffering and data staging.
• Custom Hardware Acceleration High logic element count and on-chip RAM support acceleration of compute kernels, signal processing, and protocol offload tasks.
• Embedded System Integration Flexible programmable I/O and platform configuration options support complex system control, sensor aggregation, and I/O expansion roles in commercial systems.

Unique Advantages

• High-density programmable resources: Approximately 477,000 logic elements combined with ~4.24 Mbits of embedded RAM reduce reliance on external logic and memory components.
• Broad I/O capability: 312 I/Os enable extensive peripheral connectivity and flexible banked I/O configurations for mixed-signal and multi-domain designs.
• Compact, board-friendly package: 676-FCBGA (27×27) surface-mount package supports dense PCB layouts while maintaining robust signal routing options.
• Platform-level feature set: Built on the Lattice Avant platform with documented capabilities for sysMEM, sysDSP, DDR support, SerDes/PCS, and device configuration features to streamline development.
• Commercial-grade and compliant: Operates across a 0 °C to 85 °C range and is RoHS compliant to meet standard commercial product requirements.
• Single nominal supply: Device supply specified at 820 mV for designs targeting that power domain.
