• Embedded Memory — Approximately 0.43 Mbits (434,176 bits) of on-chip RAM to support buffering, state storage and small data structures.
• I/O Count — 360 general-purpose I/Os to enable extensive external device interfacing and multiplexed signal routing.
• Power — Supported core supply voltage range of 1.14 V to 1.26 V for predictable power budgeting and system design.
• Package & Mounting — 484-BBGA package (supplier device package 484-FPBGA, 23×23) with surface-mount mounting type for compact board integration.
• Operating Environment — Industrial operating temperature range of −40 °C to 100 °C to support deployment in harsh or temperature-variable environments.
• Regulatory Compliance — RoHS compliant to meet common environmental and manufacturing requirements.

Typical Applications

• Industrial Automation — Implement control logic and custom I/O handling using the device’s 19,700 logic elements and 360 I/Os for PLCs, motor drives or factory automation interfaces.
• Embedded Systems — Use on-chip RAM and abundant I/O to prototype and deploy embedded platforms requiring custom peripherals and glue logic.
• Communications & Networking — Leverage the high I/O count and programmable logic to manage protocol bridging, packet handling or interface aggregation in networking equipment.
• Test & Measurement — Build configurable signal conditioning, data capture and processing modules where deterministic logic and numerous I/Os are needed.

Unique Advantages

• Balanced Logic and Memory: 19,700 logic elements combined with 434,176 bits of RAM provide a practical mix of programmable logic and on-chip storage for mid-range designs.
• High I/O Density: 360 I/Os enable complex external interfacing without the need for numerous additional I/O expanders.
• Industrial Temperature Rating: Specified operation from −40 °C to 100 °C supports deployments in temperature-challenging environments.
• Compact BGA Package: 484-BBGA (484-FPBGA, 23×23) allows a high pin-count implementation in a space-efficient surface-mount form factor.
• Low-Voltage Core: Narrow core voltage range (1.14 V–1.26 V) supports predictable power design and compatibility with modern low-voltage system rails.
• RoHS Compliant: Meets common environmental compliance expectations for modern manufacturing.
