• I/O Count  349 general-purpose I/O pins to support wide bus interfaces and multiple peripheral connections.
• Package & Mounting  484-BGA, FCCSPBGA package (supplier device package: 484-FCCSP, 19×19) in a surface-mount format for dense board-level integration.
• Power Supply  Voltage supply: 820 mV (device nominal supply as specified).
• Operating Temperature  Commercial operating range: 0 °C to 85 °C.
• Platform Architecture  Part of the Lattice Avant Platform with documented architecture elements such as Programmable Functional Unit (PFU) blocks, routing fabric, and clocking hierarchy.
• Clocking & Timing  Platform-level clock features include on-chip oscillator, PLLs, global and regional clock resources, dynamic clock control and synchronizers (as described in the Avant Platform documentation).
• Memory & DSP  sysMEM and sysDSP resources in the Avant Platform enable memory-centric and DSP-accelerated functions; features include single/dual-port RAM modes, FIFO modes and DSP blocks (per platform documentation).
• I/O & Interfaces  Programmable I/O cells and banking scheme with support for platform I/O standards; platform documentation also describes DDR memory support and DDRPHY options, multi-protocol PHY/PCS and SERDES capabilities.
• System Configuration & Reliability  Platform configuration options include JTAG, SEU handling guidance and enhanced configuration features described in the Avant Platform documentation.
• Compliance  RoHS compliant.

Typical Applications

• High-density programmable logic designs  Implement large-scale custom logic, state machines and hardware accelerators using 637,000 logic elements and extensive on-chip RAM.
• Memory-centric subsystems  Leverage approximately 4.24 Mbits of embedded memory and sysMEM features for buffering, FIFOs and ROM-like initialization modes.
• High-pin-count interface hubs  Use the 349 I/Os and flexible PIO banking to aggregate multiple buses, sensors and peripheral interfaces on a single device.
• Clock- and timing-critical designs  Utilize platform clocking resources including PLLs, on-chip oscillator and dynamic clock control to manage complex timing domains.

Unique Advantages

• High logic density: 637,000 logic elements provide substantial room for complex designs and integration of multiple functions into a single device, reducing board-level component count.
• On-chip memory for system efficiency: Approximately 4.24 Mbits of embedded RAM enables local buffering and memory cascades to simplify external memory requirements.
• Extensive I/O capability: 349 I/Os support broad peripheral connectivity and wide parallel interfaces without immediate need for external GPIO expanders.
• Platform-level resources: Avant Platform features such as PFU blocks, sysDSP, DDR support and SERDES/PCS options provide a documented architectural foundation for building diverse FPGA-based subsystems.
• Compact, manufacturable package: 484-FCCSP (19×19) ball grid package in surface-mount format eases placement in space-constrained designs while supporting automated assembly.
• Commercial-grade readiness: Specified for 0 °C to 85 °C operation and RoHS compliant for mainstream electronic product deployment.
