XC4028XL-09HQ304C

The XC4028XL-09HQ304C is a commercial-grade field programmable gate array (FPGA) from the XC4000E/X family. It provides 2,432 logic elements, 32,768 bits of on-chip RAM and up to 256 general-purpose I/O lines in a 304-pin BFQFP exposed pad package, supporting system designs that require moderate logic density and substantial I/O capacity.

This surface-mount FPGA operates from a 3.0 V to 3.6 V supply and is specified for commercial temperature operation from 0 °C to 85 °C, offering a balanced combination of integration and board-level compatibility for a range of embedded designs.

Key Features

• Logic Capacity  2,432 logic elements with approximately 28,000 equivalent gates to implement combinational and sequential logic functions.
• Embedded Memory  32,768 bits of on-chip RAM for small data buffers, state storage and control/state-machine implementations.
• I/O Density  Up to 256 general-purpose I/O pins to support broad interfacing and parallel connectivity needs.
• Package  304-BFQFP exposed pad package (supplier device package: 304-PQFP, 40×40) in a surface-mount form factor for compact PCB integration and thermal conduction through the exposed pad.
• Power  Operates from a 3.0 V to 3.6 V supply range suitable for common commercial power rails.
• Operating Range  Commercial temperature grade specified from 0 °C to 85 °C for standard environment deployments.
• Environmental Compliance  RoHS compliant.

Typical Applications

• I/O-Intensive Interface Logic  Implement custom bus interfaces, parallel converters or glue logic where up to 256 I/O lines are required.
• Embedded Control and Glue Logic  Use the 2,432 logic elements and on-chip RAM to implement control state machines, protocol handling and mid-density logic functions.
• Compact Surface-Mount Designs  Suitable for PCBs that require a high-pin-count, surface-mount FPGA in a 304-BFQFP exposed pad package.
• Commercial Temperature Systems  Target systems and products that operate within 0 °C to 85 °C and require RoHS-compliant components.

Unique Advantages

• Balanced Logic and Memory  Combines 2,432 logic elements with 32,768 bits of RAM to support both control logic and modest data buffering without external memory.
• High I/O Count  256 I/O pins enable direct connection to multiple peripherals, buses and parallel interfaces, reducing the need for external interface chips.
• Surface-Mount, Exposed-Pad Package  304-BFQFP with exposed pad provides a compact footprint and improved board-level thermal conduction for high-pin-count designs.
• Commercial-Grade Operating Range  Rated for 0 °C to 85 °C, aligning with a wide range of standard commercial applications and environments.
• RoHS Compliant  Meets common environmental regulatory requirements for lead-free assemblies.
• Standard Supply Voltage  3.0 V to 3.6 V operation fits common commercial power rails for straightforward integration.
