LAV-AT-E70-1CBG484I

The LAV-AT-E70-1CBG484I is an Avant™-E FPGA from Lattice Semiconductor, delivered in a compact 484-FCCSP (19×19) / 484-BGA package for surface-mount assembly. It integrates programmable logic, embedded memory, and a broad set of on-chip system features documented in the Avant platform datasheet.

This device is aimed at industrial designs requiring substantial logic capacity, multiple I/O, embedded RAM, and integrated subsystem blocks such as clocking, DDR memory support, SERDES/PMA and programmable I/O. Its specification set supports deployment across applications that need flexible, reprogrammable logic and system-level integration.

Key Features

• Logic Capacity — Provides 637,000 logic elements for implementing custom digital logic and control functions.
• Embedded Memory — Includes a total of 4,239,360 bits of on-chip RAM (approximately 4.24 Mbits) for data buffering, FIFOs, and working memory.
• I/O Density — 349 user I/O pins to support diverse interface and signaling requirements.
• On‑Chip Clocking — Platform-level clocking architecture with on-chip oscillator, PLLs, global and regional clocks, and dynamic clock control as described in the Avant platform documentation.
• Memory and PHY Support — Device documentation covers sysMEM memory primitives, sysDSP resources, DDR memory support and DDRPHY integration for memory interface implementations.
• SERDES and Protocol Support — Architecture includes SERDES/PMA blocks and multi‑protocol PCS/PHY integration for high‑speed serial link integration as outlined in the platform overview.
• Configuration and Reliability — Enhanced configuration options including JTAG and Single Event Upset (SEU) handling are addressed in the product documentation.
• Package and Mounting — Available in 484-FCCSP (19×19) / 484-BGA package; surface-mount mounting type.
• Operating Range — Industrial-grade operating temperature range from −40 °C to 100 °C and a specified supply voltage of 820 mV.
• Compliance — RoHS compliant.

Typical Applications

• High-speed communications — Use the device’s SERDES/PMA and multi-protocol PCS/PHY capabilities to implement flexible serial link endpoints and protocol bridging.
• Memory interface controllers — Leverage sysMEM primitives and DDRPHY support for custom DDR memory controllers and buffering logic.
• Signal processing and acceleration — Combine abundant logic elements and sysDSP resources for hardware-accelerated processing, filtering, and data path functions.
• Protocol conversion and I/O aggregation — Use 349 I/Os and programmable I/O cells to consolidate and translate between multiple peripheral interfaces in embedded systems.

Unique Advantages

• Substantial logic density: 637,000 logic elements enable complex, large-scale custom hardware designs without external programmable logic.
• On-chip memory capacity: Approximately 4.24 Mbits of embedded RAM reduces reliance on external buffering and simplifies board-level memory architectures.
• Integrated high-speed interfaces: SERDES/PMA and DDRPHY support reduce the need for separate interface ASICs when implementing serial links and memory controllers.
• Comprehensive clocking and timing features: Built-in oscillator, PLLs and regional/global clock structures support flexible and deterministic clocking topologies.
• Industrial temperature rating: −40 °C to 100 °C operating range supports deployment in industrial environments.
• Compact, surface-mount packaging: 484-FCCSP (19×19) / 484-BGA options enable space-efficient board layouts.
