• Logic Capacity — 637,000 logic elements to implement complex custom logic, control, and data-path functions.
• Embedded Memory — Approximately 4.24 Mbits of on-chip RAM (4,239,360 bits) for buffers, state storage, and embedded data structures.
• Rich I/O — 502 user I/O pins to support extensive peripheral interfacing and multi-channel designs.
• Package & Mounting — 841-BGA (841-FCCSP, 15×13) surface-mount package for compact board integration.
• Industrial Temperature Range — Guaranteed operation from -40 °C to 100 °C for demanding environmental conditions.
• Supply Voltage — Device specified for a supply voltage at 820 mV.
• Platform Architecture — Lattice Avant platform architecture with Programmable Functional Units (PFU), clocking (on-chip oscillator, PLL, global/regional/edge clocks), sysMEM, sysDSP, and programmable I/O cell structures.
• Memory and Interface Support — Platform-level support for sysMEM configurations (single/dual/pseudo-dual port, FIFO, RAM init/ROM modes) and DDR memory PHY capabilities.
• High-speed Interfaces — Series-level SERDES and PCS blocks and multi-protocol PHY/PCS integration as part of the Avant platform.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — High logic density and industrial temperature range enable complex control, sequencing, and deterministic I/O for factory automation.
• Communications Infrastructure — Large I/O count and platform SERDES/PCS support facilitate protocol bridging, packet processing, and high-speed interface implementations.
• Edge Computing and Signal Processing — Substantial logic elements and embedded RAM support on-device acceleration and buffering for edge DSP workloads.
• Memory Interface and Bridging — sysMEM and DDRPHY support enable memory buffering, caching, and interface bridging for embedded systems.

Unique Advantages

• High Logic Density: 637,000 logic elements provide the capacity to consolidate multiple functions into a single FPGA, reducing system complexity.
• Significant On-Chip RAM: Approximately 4.24 Mbits of embedded memory reduces dependence on external memory for many buffering and state-storage tasks.
• Extensive I/O Count: 502 I/O pins allow flexible connectivity to sensors, buses, high-speed transceivers, and peripheral devices.
• Industrial Temperature Operation: Rated from -40 °C to 100 °C to meet thermal requirements for harsh or outdoor deployments.
• Integrated Avant Platform Capabilities: Platform-level clocking, sysDSP, programmable I/O cells, and SERDES/PCS enable complex timing, DSP, and high-speed interface implementations.
• Compact Package: 841-FCCSP BGA (15×13) offers a space-efficient footprint for densely packed PCBs.
