The device is RoHS compliant and designed for surface-mount assembly.

Key Features

• Logic Capacity  Provides 32,000 logic elements to implement custom digital functions and control logic within a single FPGA device.
• Embedded Memory  Includes approximately 339,968 bits of on-chip RAM (≈0.34 Mbits) for buffering, FIFOs, and small data storage requirements.
• I/O Density  Offers 331 I/Os to support complex interfacing, parallel buses, and multi-channel connectivity without external multiplexing.
• Power and Voltage  Operates from a low-voltage supply range of 1.14 V to 1.26 V to match modern low-voltage system rails.
• Package and Mounting  Supplied in a 484-FPBGA (23 × 23 mm) package — listed as 484-BBGA — and intended for surface-mount PCB assembly.
• Operating Range  Commercial grade operation from 0 °C to 85 °C suitable for standard commercial and embedded environments.
• Environmental Compliance  RoHS compliant to meet common environmental and manufacturing requirements.

Typical Applications

• Programmable logic implementations  Use the device where reconfigurable digital logic is required, leveraging 32,000 logic elements for custom datapaths and control functions.
• I/O-heavy interfaces  Deploy in designs that need many parallel or multi-protocol connections, taking advantage of the 331 available I/Os.
• Embedded buffering and small-data storage  Utilize the approximately 0.34 Mbits of on-chip RAM for local buffering, FIFOs, or state storage without external memory.

Unique Advantages

• High logic density: 32,000 logic elements enable substantial on-chip logic implementation while maintaining a single-chip solution.
• Significant embedded memory: Approximately 0.34 Mbits of RAM reduces reliance on external memory for short-term storage and buffering.
• Extensive I/O count: 331 I/Os support complex interfacing and reduce the need for additional I/O expanders.
• Compact, manufacturable package: 484-FPBGA (23 × 23 mm) in a surface-mount format simplifies PCB layout for dense system designs.
• Low-voltage operation: Narrow supply range (1.14–1.26 V) aligns with modern low-voltage digital systems to simplify power supply design.
• RoHS compliant: Meets common environmental standards for electronics manufacturing and assembly.
