XC4020XL-1HT176C

The XC4020XL-1HT176C is an AMD XC4000E/X family field-programmable gate array (FPGA) offered in a 176-LQFP exposed pad package. Designed for commercial-grade applications, it provides mid-density programmable logic with a balanced mix of logic elements, embedded RAM and I/O resources for control, interfacing and integration tasks.

With support for a 3.0 V–3.6 V supply and up to 145 general-purpose I/Os, this surface-mount FPGA targets designs that require moderate gate counts, on-chip memory and a compact LQFP footprint.

Key Features

• FPGA Core Field-programmable gate array architecture from the XC4000E/X family for customizable digital logic implementation.
• Logic Resources Approximately 1,862 logic elements to implement combinational and sequential logic functions.
• Embedded Memory 25,088 bits of on-chip RAM (≈0.025 Mbits) for small buffers, FIFOs or register files.
• I/O Density Up to 145 general-purpose I/O pins to support parallel interfaces, peripheral control and signal routing.
• Gate Capacity Equivalent to 20,000 gates for mid-range digital integration.
• Power Operates from a 3.0 V to 3.6 V supply range to match common commercial logic rails.
• Package & Mounting 176-LQFP exposed pad package (supplier device package: 176-TQFP 24×24) in a surface-mount configuration for PCB assembly and thermal conduction through the exposed pad.
• Commercial Temperature Grade Rated for operation from 0 °C to 85 °C, suitable for commercial embedded applications.
• Regulatory RoHS compliant.

Typical Applications

• Commercial Embedded Systems — Implement custom control logic, peripheral interfaces and glue logic in consumer and commercial products using the FPGA's logic and I/O resources.
• Prototyping & Evaluation — Rapidly prototype digital designs and verify logic functions on a mid-density FPGA platform.
• Interface Bridging — Create parallel and custom interface bridges leveraging up to 145 I/Os for signal routing and protocol adaptation.
• Sensor & Peripheral Control — Perform local data aggregation, timing control and peripheral management using on-chip logic and RAM.

Unique Advantages

• Balanced Mid-Density Resource Set: Approximately 1,862 logic elements and 25,088 bits of embedded RAM provide a useful midpoint between small CPLDs and larger FPGAs for common commercial designs.
• Generous I/O Count: Up to 145 I/Os enable multiple parallel interfaces or a mix of control and data lines without external multiplexing.
• Compact Surface-Mount Package: 176-LQFP exposed pad (24×24) offers a small PCB footprint with an exposed pad for improved thermal path and assembly compatibility.
• Commercial Temperature Range: Rated 0 °C to 85 °C to match typical commercial deployment environments.
• Simple Power Requirements: Single-supply operation from 3.0 V to 3.6 V simplifies power-rail design in systems using standard logic levels.
• RoHS Compliant: Meets environmental compliance requirements for lead-free assemblies.
