Key Features

• Core Logic — 637,000 logic elements provide substantial programmable logic resources for complex designs and hardware acceleration.
• Embedded Memory — Approximately 4.24 Mbits of on-chip RAM (4,239,360 bits) with sysMEM features such as single/dual/pseudo-dual port modes, FIFO support, RAM initialization/ROM operation, and memory cascading.
• I/O Capacity — 554 user I/Os supporting multi-protocol interfaces and flexible sysI/O banking as described in the Avant platform architecture.
• Clocking & Timing — Integrated clock infrastructure including on-chip oscillator, PLL, global/regional/edge clock domains, dynamic clock select/control, DLL delay and clock synchronizers for precise timing and clock distribution.
• High-speed Interfaces & PHY — Platform-level support for SERDES, PCS, multi-protocol PHY integration and DDR memory support with DDRPHY and DQS grouping for robust high-bandwidth interface implementations.
• Signal Processing — sysDSP blocks included in the architecture for dedicated DSP processing capabilities.
• Device Configuration & Debug — Enhanced configuration options, JTAG support, SEU handling and trace ID facilities for configuration, verification and system reliability.
• Package & Mounting — 1156‑BBGA (1156‑FCBGA) surface-mount package, supplier package specified as 1156‑FCBGA (35×35), suitable for high-density board layouts.
• Commercial Grade & Compliance — Commercial temperature grade (0 °C to 85 °C) and RoHS compliant.
• Power — Core voltage supply specified at 820 mV.

Typical Applications

• High-performance communications — Implement multi-protocol PHYs, SERDES/PCS and high-bandwidth interfaces for networking and data transport systems.
• Memory interface controllers — Leverage sysMEM and DDRPHY support to implement DDR memory controllers, FIFOs and complex memory hierarchies.
• Signal processing and acceleration — Use sysDSP resources and large logic fabric for compute acceleration, filtering and real-time data processing.
• Custom I/O and protocol bridging — Deploy the extensive I/O count and programmable I/O cells to consolidate peripherals, bridge interfaces, or implement custom protocol adapters.

Unique Advantages

• High logic density: 637,000 logic elements enable large-scale FPGA implementations without multiple devices.
• Substantial embedded memory: Approximately 4.24 Mbits of on-chip RAM supports large buffers, FIFOs and complex state machines with flexible memory modes.
• Extensive I/O footprint: 554 user I/Os provide the pin-count needed for multi-interface systems and dense board-level integration.
• Comprehensive clocking and timing: On-chip oscillator, PLLs, multiple clock domains and dynamic clock control simplify timing architecture and system synchronization.
• Advanced interface support: Built-in SERDES/PCS, multi-protocol PHY options and DDRPHY support enable high-speed link and memory subsystem implementations.
• Compact, surface-mount package: 1156‑FCBGA (35×35) package offers a high-pin-count solution in a compact footprint for PCB space-constrained applications.
