• High I/O Count  298 user I/Os enable dense peripheral connections, broad interface support, and flexible pin assignments for board-level integration.
• Package & Mounting  400‑LFBGA package (supplier package listed as 400‑CABGA, 17×17) in a surface-mount form factor for compact PCB integration.
• Industrial Temperature Grade  Specified operating range from -40 °C to 100 °C, suitable for industrial temperature environments.
• Core Voltage  Supports a core supply window of 0.95 V to 1.05 V, matching modern low-voltage FPGA power domains.
• Family-Level Peripherals (MachXO5‑NX)  The MachXO5‑NX family datasheet references architecture and peripherals such as programmable I/O, DDR memory support, PCIe, cryptographic engine, on‑chip oscillator, user flash memory (UFM), sysDSP and sysMEM blocks—features that the family supports as described in the MachXO5‑NX documentation.
• Regulatory  RoHS compliant.

Typical Applications

• Industrial Control  Use as programmable glue logic and interface concentrator in industrial automation and control equipment where extended temperature operation and high I/O density are required.
• Protocol Bridging & Connectivity  Deploy for board-level protocol conversion, bus bridging, and I/O aggregation leveraging the high I/O count and family support for interfaces documented in the MachXO5‑NX datasheet.
• Embedded Memory and Buffering  Implement local data buffering, FIFOs, and temporary storage using the device’s embedded RAM to support deterministic data paths in real-time systems.
• Security and System Functions  Leverage MachXO5‑NX family features such as cryptographic engine and user flash (UFM) for secure boot, key storage, and system-level management (as described in the family datasheet).

Unique Advantages

• High Logic Density:  96,000 logic elements enable consolidation of multiple discrete functions into a single programmable device, reducing BOM and board area.
• Substantial On‑Chip Memory:  Approximately 8.16 Mbits of embedded RAM supports local buffering and state storage, minimizing external memory needs for many use cases.
• Large I/O Count:  298 I/Os provide flexibility for connecting sensors, memory, transceivers, and peripherals without needing external multiplexers.
• Industrial Robustness:  -40 °C to 100 °C operating range and industrial grade classification fit factory, instrumentation, and fielded equipment scenarios.
• Compact, Surface‑Mount Packaging:  400‑LFBGA (400‑CABGA, 17×17) enables high-density PCB layouts while supporting automated assembly processes.
• Documented Family Capabilities:  MachXO5‑NX family documentation lists advanced architecture and peripherals (PCIe, DDR support, cryptographic engine, UFM, sysDSP/sysMEM), offering a clear upgrade path within the family for designs requiring those functions.
