Key Features

• Core Logic Density  Approximately 637,000 logic elements available for implementing complex programmable logic and custom datapaths.
• Embedded Memory  Approximately 4.24 Mbits of on-chip RAM (total RAM bits: 4,239,360) for local buffering, FIFOs, and memory-mapped logic.
• I/O Capacity  553 user I/O pins to support extensive peripheral and system interfacing requirements.
• Clocking and Timing  Integrated clocking architecture with on-chip oscillator and PLL resources, plus global, regional, and edge clock domains as described in the Avant platform overview.
• Programmable I/O and PHY  Programmable I/O cells, sysI/O banking, DDRPHY support, and SERDES/PCS blocks are included in the Avant platform documentation for high-speed interface implementations.
• DSP Resources  sysDSP blocks are part of the platform architecture to accelerate arithmetic and signal-processing tasks (see platform documentation).
• Configuration and Reliability  Device configuration options include JTAG and documented SEU handling provisions outlined in the Avant platform datasheet.
• Package and Mounting  Supplied in a 1156‑FCBGA (35×35 mm) package; mounting type is surface mount.
• Supply and Temperature  Voltage supply listed as 820 mV; industrial operating temperature range from -40 °C to 100 °C.
• RoHS Compliance  RoHS status: Compliant.

Typical Applications

• Industrial Control Systems  Industrial-grade FPGA resources and extended temperature range make the device suitable for programmable logic in control and automation equipment.
• High‑I/O Embedded Systems  Large I/O count supports systems requiring many peripheral connections and flexible pin usage.
• Memory‑Rich, Logic‑Intensive Designs  Substantial on-chip RAM and high logic element count enable local buffering and complex state machines or datapaths.

Unique Advantages

• High Logic Capacity: The device’s approximately 637,000 logic elements enable integration of large custom functions and complex control logic into a single FPGA.
• Significant Embedded Memory: Roughly 4.24 Mbits of on-chip RAM reduces dependence on external memory for many buffering and FIFO use cases.
• Large I/O Footprint: 553 I/O pins facilitate rich peripheral connectivity and system interfacing without extensive external multiplexing.
• Comprehensive On‑Chip Resources: The Avant platform’s documented features—clocking, PLLs, DDRPHY, sysDSP, and SERDES/PCS—provide integrated building blocks for common FPGA functions.
• Industrial‑Grade Operation: Specified operating range from -40 °C to 100 °C supports deployment in environments requiring wider temperature tolerance.
• Compact FCBGA Packaging: The 1156‑FCBGA (35×35) package delivers high integration density in a surface-mount form factor.
