XC4020E-1HQ240C

The XC4020E-1HQ240C is a field programmable gate array (FPGA) from AMD in the XC4000E/X family, supplied in a 240-BFQFP exposed pad package. It provides a balance of programmable logic, on-chip RAM, and high I/O count for commercial-grade digital designs that require configurable logic and memory resources.

Designed for systems operating from a 4.75 V to 5.25 V supply and rated for 0 °C to 85 °C, this device targets general-purpose embedded applications that need moderate gate density and flexible I/O in a surface-mount PQFP footprint.

Key Features

• FPGA Core 1,862 logic cells and 20,000 gates provide configurable logic capacity for custom glue logic, state machines, and parallel datapaths.
• Logic Resources 784 logic elements available to structure and partition designs for modular implementation.
• On-Chip Memory Approximately 0.025 Mbits of embedded memory (25,088 bits) for small buffers, FIFOs, and register storage.
• I/O 193 user I/O pins support wide peripheral interfacing and multiple external signal connections.
• Power Single-supply operation from 4.75 V to 5.25 V simplifies integration into standard 5 V systems.
• Package 240-pin BFQFP with exposed pad (supplier package: 240-PQFP, 32×32) in a surface-mount configuration for board-level thermal management and compact layout.
• Operating Conditions Commercial grade device rated for 0 °C to 85 °C operation.
• Compliance RoHS compliant.

Typical Applications

• Custom Control Logic — Implement application-specific state machines and protocol translators where moderate logic density and plentiful I/O are required.
• Interface Bridge — Bridge parallel and serial peripherals or aggregate multiple signals using the available I/O and embedded memory resources.
• Prototyping and Development — Use the FPGA’s reprogrammable logic for iterative hardware development and proof-of-concept implementations.
• Embedded Signal Conditioning — Implement preprocessing or formatting of digital sensor data before passing to downstream systems.

Unique Advantages

• Balanced Logic and Gate Count: 20,000 gates and 1,862 logic cells offer suitable capacity for medium-complexity designs without excessive overhead.
• High I/O Density: 193 I/O pins enable extensive external connectivity for multi-signal interfaces and peripheral expansion.
• On-Board Memory: Approximately 0.025 Mbits of embedded RAM supports small buffers and data staging without external memory.
• Standard 5 V Supply: Operates from 4.75 V to 5.25 V for straightforward integration into legacy 5 V systems and common power rails.
• Compact Surface-Mount Package: 240-BFQFP with exposed pad supports PCB space efficiency and improved thermal conduction to the board.
• RoHS Compliant: Meets RoHS requirements for environmentally conscious manufacturing.
