• I/O Density — 553 user I/O pins to support broad peripheral and interface connectivity.
• Package & Mounting — 1156-FCBGA (35×35) package in a surface-mount form factor for high-density PCB integration.
• Operating Range — Industrial-grade operation from −40 °C to 100 °C for deployment in harsh thermal environments.
• Power — Voltage supply specified at 820 mV (per product data).
• Avant Platform Architecture — Device aligns with the Lattice Avant platform architecture which includes programmable functional unit (PFU) blocks, flexible routing and clocking structures, on-chip PLL/DLL options, and device configuration features.
• Memory and DSP Subsystems — Datasheet coverage indicates sysMEM and sysDSP blocks for memory cascading, FIFO modes, ROM/initialization, and DSP functions useful for signal processing and compute tasks.
• Programmable I/O and PHY Support — Architecture includes programmable I/O cell (PIC) features, DDR memory support with DDRPHY grouping, and SERDES/PCS building blocks for multi-protocol PHY integration.
• Configuration & Reliability — Device configuration supports enhanced options including JTAG and SEU handling as described in the Avant platform documentation.
• Compliance — RoHS compliant for regulatory alignment in standard manufacturing processes.

Typical Applications

• High‑speed interfaces and protocol bridging — Utilizes SERDES/PCS and multi‑protocol PHY capabilities for complex serial link aggregation, protocol conversion, and interface bridging.
• DDR memory interfacing and buffering — DDRPHY and sysMEM features support designs that require external DDR memory interfaces and high-bandwidth buffering.
• Embedded compute and DSP acceleration — sysDSP and abundant logic elements enable implementation of custom accelerators and signal processing pipelines.
• Industrial control and automation — Industrial-grade temperature range and broad I/O density suit automation, motor control, and factory systems requiring robust operation.

Unique Advantages

• Substantial programmable capacity: 637,000 logic elements provide the headroom for complex, high‑gate‑count designs without partitioning across multiple devices.
• Integrated memory resources: Approximately 4.24 Mbits of on‑chip RAM reduces dependency on external memory for many buffering and local storage needs.
• High I/O count: 553 I/O pins simplify system integration by accommodating multiple parallel interfaces and control signals on a single device.
• Industrial thermal capability: −40 °C to 100 °C rating supports deployment in demanding thermal environments common in industrial applications.
• Avant platform ecosystem: Architecture elements documented in the Avant platform (PFU blocks, clocking, sysMEM, sysDSP, SERDES/PCS) provide a coherent foundation for implementing a wide range of protocols and compute functions.
• Production-ready package: 1156-FCBGA (35×35) surface-mount package aligns with compact, high-density PCB designs and standard assembly flows.
