• I/O Capacity — 303 I/O pins to support high-channel-count interfaces and extensive peripheral connectivity.
• Package and Mounting — Supplied in an 841-BGA FCCSPBGA package (supplier device package: 841-FCCSP, 15×13); surface-mount mounting type for standard PCB assembly.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C to meet demanding environmental requirements.
• Power Supply — Specified supply voltage at 820 mV as provided in product documentation.
• Environmental Compliance — RoHS compliant to meet lead-free assembly requirements.
• Comprehensive Datasheet Coverage — Series datasheet includes detailed DC and switching characteristics, I/O electrical standards, PLL and oscillator characteristics, and other platform-level specifications for system-level design.

Typical Applications

• High‑density logic designs — Use the device where large programmable logic capacity and embedded RAM are required to implement complex digital functions.
• High‑channel I/O systems — Deploy in applications that require aggregation or routing of many signals, benefiting from the 303 I/O count.
• Industrial controls and automation — Industrial-grade temperature rating and surface-mount packaging enable deployment in factory and process-control environments.

Unique Advantages

• Substantial logic capacity: Approximately 637,000 logic elements let you consolidate multiple discrete functions into a single programmable device, simplifying system architecture.
• On‑chip memory for local buffering: Approximately 4.24 Mbits of embedded RAM reduces external memory dependencies and lowers BOM complexity.
• High I/O count: 303 I/O pins provide flexibility for interfacing with sensors, peripherals, or multi-channel data paths without external multiplexing.
• Industrial thermal tolerance: −40 °C to 100 °C operating range supports designs that must operate reliably across wide temperature variations.
• Compact, assembly‑friendly package: 841-FCCSP (15×13) BGA format and surface-mount mounting support dense PCB layouts and standard manufacturing processes.
• Standards and documentation: Series datasheet delivers detailed electrical and timing characteristics to support verification and system integration.
