Key Features

• Logic Capacity — 637,000 logic elements to implement complex programmable logic and custom hardware functions.
• Embedded Memory — Approximately 4.24 Mbits of total on-chip RAM for data buffering, state storage, and memory-intensive functions.
• I/O Density — 502 general-purpose I/Os to support dense interfacing and broad peripheral connectivity.
• Package and Mounting — 841-BGA / 841-FCCSP (15×13) supply-device package for compact surface-mount integration.
• Commercial Temperature Grade — Rated for operation from 0 °C to 85 °C for standard commercial deployments.
• Avant Platform Architecture — Platform-level architecture includes programmable functional unit (PFU) blocks, routing, and a flexible clocking structure (on-chip oscillator, PLLs, global/regional/edge clocks) as described in the Avant documentation.
• Memory and DSP Subsystems — Platform includes sysMEM capabilities (single/dual/pseudo-dual port modes, FIFO modes) and sysDSP support for on-chip memory and DSP functions.
• High-Speed Interface Support — Platform documentation references SERDES/PCS blocks, Multi-Protocol PHY (MPPHY) integration, and DDR PHY support for high-speed serial and memory interfaces.
• Configuration and Reliability Features — Device configuration options include enhanced configuration, JTAG access, and Single Event Upset (SEU) handling mechanisms as documented for the Avant platform.
• Standards and Compliance — RoHS compliant; commercial-grade product classification.

Typical Applications

• Protocol and Interface Bridging — Use the device’s SERDES/PCS and Multi-Protocol PHY support to implement high-speed protocol conversion and interface bridging.
• Memory Controller and Buffering — Leverage sysMEM and DDR PHY support for memory controller logic, data buffering, and FIFO implementations.
• Custom DSP and Acceleration — Implement DSP pipelines and custom compute blocks using the platform’s sysDSP and large logic element count.
• Dense I/O Control — Utilize 502 I/Os for board-level peripheral aggregation, sensor interfacing, and complex I/O routing.

Unique Advantages

• High logic density: 637,000 logic elements enable integration of substantial custom logic without extensive external components.
• Significant on-chip memory: Approximately 4.24 Mbits of embedded RAM supports large buffering and state storage directly on-chip.
• Broad I/O count: 502 I/Os provide flexibility for systems that require many external connections or mixed-signal interfacing.
• Flexible platform capabilities: Avant platform features—clocking, PFU blocks, sysMEM, sysDSP, and SERDES/PHY support—offer adaptable building blocks for diverse designs.
• Compact package: 841-FCCSP (15×13) package for dense PCB layouts while maintaining high I/O and logic capacity.
• Commercial readiness: RoHS compliance and a 0 °C to 85 °C operating range align with standard commercial product requirements.
