• Embedded Memory  Approximately 0.37 Mbits of on-chip RAM (368,640 total RAM bits) for buffering, state machines, and small data storage needs.
• I/O Resources  311 user I/O pins to support multiple parallel interfaces and signal connections directly from the FPGA fabric.
• Power Supply  Operates from a defined core supply range of 1.14 V to 1.26 V, enabling predictable integration with regulated power domains.
• Package and Mounting  400-BGA package (supplier device package: 400-FBGA, 21 × 21 mm) designed for surface-mount assembly in space-constrained boards.
• Automotive Qualification  Grade: Automotive with AEC-Q100 qualification for designs requiring industry-recognized component-level automotive qualification.
• Operating Temperature  Rated for −40°C to 125°C operation to support deployment across extended temperature ranges.
• Environmental Compliance  RoHS compliant for adherence to common environmental and lead-free manufacturing requirements.

Typical Applications

• Automotive Control Systems  Automotive-grade qualification (AEC-Q100) and −40°C to 125°C range allow use in control and monitoring functions where reprogrammable logic and environmental robustness are required.
• Protocol Bridging and Interface Aggregation  311 I/Os and programmable logic resources facilitate implementation of custom interface bridges, signal multiplexing, and glue logic between heterogeneous peripherals.
• Deterministic Control and State Machines  8,064 logic elements and embedded RAM support implementation of timing-critical control, sequencing, and finite state machines.
• Compact Embedded Systems  The 400-FBGA (21 × 21 mm) surface-mount package enables integration into size-constrained systems that require on-board programmable logic.

Unique Advantages

• Automotive-Grade Qualification: AEC-Q100 qualification and automotive grade marking provide confidence for designs targeting transportation and other demanding environments.
• Ample Logic Capacity: 896 CLBs and 8,064 logic elements deliver sufficient resources for medium-complexity custom logic without excessive board-level component count.
• High I/O Count: 311 I/Os simplify direct interfacing to multiple peripherals and parallel buses, reducing the need for external glue logic.
• On-Chip Memory: Approximately 0.37 Mbits of embedded RAM supports buffering and small data-store requirements without external memory.
• Wide Temperature and Defined Supply Range: Operation from −40°C to 125°C and a clearly specified core supply (1.14 V–1.26 V) aid reliable system-level integration and validation.
• Compact BGA Footprint: The 400-FBGA (21 × 21 mm) package provides a dense, surface-mount solution for space-constrained PCBs.
