XC4028XL-3HQ304I

The XC4028XL-3HQ304I is a field programmable gate array (FPGA) IC from AMD in the XC4000E/X family. It provides a balanced combination of logic capacity, on-chip RAM, and a high count of I/O pins for designs that require moderate logic integration and substantial external interfacing.

With 2,432 logic elements, 32,768 bits of on-chip RAM, and 256 I/O, this device is suited to industrial applications and embedded designs that need robust temperature range and a compact surface-mount footprint.

Key Features

• Core Logic 2,432 logic elements and approximately 28,000 gates deliver the programmable logic resources for custom digital functions.
• On-Chip Memory 32,768 bits of total RAM provide local storage for state machines, FIFOs, and small data buffers.
• I/O Density 256 general-purpose I/O pins enable broad external device interfacing and parallel connectivity options.
• Package & Mounting 304-BFQFP exposed pad package (supplier device package: 304-PQFP, 40 × 40 mm) in a surface-mount form factor for compact board-level integration.
• Power Operates from a 3.0 V to 3.6 V supply range to match common 3.3 V system rails.
• Industrial Temperature Range Rated for operation from −40 °C to 100 °C to meet demanding environmental requirements.
• Environmental Compliance RoHS compliant.

Typical Applications

• Industrial Control and Automation Suitable for control logic and I/O-heavy interfaces that require operation across −40 °C to 100 °C and many external connections.
• Embedded System Glue Logic Use the device to implement custom interface logic, bus bridging, and peripheral control where 256 I/O and 2,432 logic elements meet integration needs.
• Prototyping and Development Provides on-chip RAM and moderate gate count for algorithm validation and hardware proof-of-concept work in surface-mount designs.
• Custom Peripheral Integration Ideal for designs that require consolidating multiple discrete functions into a single programmable device with ample I/O.

Unique Advantages

• Balanced Logic and I/O Count: 2,432 logic elements combined with 256 I/O allow designers to implement complex I/O-centric functions without excessive partitioning across multiple devices.
• Compact, Board-Friendly Package: The 304-pin BFQFP with exposed pad and surface-mount mounting simplifies thermal management and PCB routing for dense assemblies.
• Industrial Reliability: Rated operation from −40 °C to 100 °C supports deployment in temperature-challenging environments.
• On-Device RAM: 32,768 bits of on-chip RAM reduces dependence on external memory for small buffers and state storage, simplifying BOM and board layout.
• Standard 3.3 V Supply Range: Compatibility with 3.0–3.6 V systems eases integration into common embedded power architectures.
