XC4028XL-2BG352I

The XC4028XL-2BG352I is a field programmable gate array (FPGA) IC from AMD in the XC4000E/X family. It provides on-chip programmable logic and connectivity in a 352-LBGA exposed pad package suited for surface-mount applications.

This FPGA combines a defined logic fabric, embedded memory and a high I/O count to address programmable digital logic and interfacing needs in industrial-grade environments operating from -40 °C to 100 °C.

Key Features

• Logic Capacity  1024 logic blocks and 2,432 logic elements (cells) enable implementation of custom digital logic functions and control state machines.
• Embedded Memory  Approximately 32 kbits of on-chip RAM provide local storage for buffering, small FIFOs and state retention.
• I/O Density  256 user I/O pins support extensive external interfacing for peripheral control, parallel buses and signal routing.
• Gate Count  Approximately 28,000 gates, giving a clear reference for design partitioning and resource planning.
• Power and Supply  Operates from a 3.0 V to 3.6 V supply window to match standard digital system rails.
• Package and Mounting  352-LBGA exposed pad, metal package (supplier package: 352-MBGA, 35×35) for surface-mount assembly and thermal management.
• Industrial Temperature Rating  Specified for -40 °C to 100 °C operation, supporting deployment in industrial environments.
• RoHS Compliance  Meets RoHS environmental requirements for lead-free manufacturing and assembly.

Typical Applications

• Custom digital logic and prototyping  Use the XC4028XL-2BG352I to implement bespoke state machines, glue logic and proof-of-concept digital designs where reconfigurable logic is required.
• I/O-heavy interfacing  With 256 I/O pins, the device is suitable for parallel bus bridging, peripheral aggregation and signal routing between subsystems.
• Embedded control and finite-state systems  The combination of logic elements and approximately 32 kbits of on-chip RAM supports control algorithms, small data buffering and local decision-making in industrial equipment.

Unique Advantages

• Balanced logic and I/O capacity: 2,432 logic elements combined with 256 I/O pins let you implement both mid-complexity logic and extensive external interfaces without immediate need for external glue components.
• On-chip embedded memory: Approximately 32 kbits of RAM enable local buffering and small data storage close to your logic, reducing external memory dependency for many control tasks.
• Industrial temperature range: Rated from -40 °C to 100 °C for reliable operation in industrial environments and harsher operating conditions.
• Standard 3.0–3.6 V supply: Compatibility with common digital supply rails simplifies power-supply design and integration into existing systems.
• Compact, thermally aware package: 352-LBGA exposed pad, metal package supports surface-mount assembly while providing a thermal path for heat dissipation in dense board layouts.
• RoHS-compliant: Meets lead-free manufacturing requirements for modern production processes.
