XC4020XL-1PQ240I

The XC4020XL-1PQ240I is an AMD field-programmable gate array (FPGA) in the XC4000E/X family designed for industrial applications. It offers a compact, surface-mount package with a balanced combination of logic density, on-chip memory, and I/O count suited for embedded control, digital signal interfacing, and custom logic functions.

Key Features

• Core Logic Provides 1,862 logic elements for implementing combinational and sequential logic blocks and custom state machines.
• Embedded Memory Includes 25,088 bits of on-chip RAM to support data buffering, small FIFOs, and register files directly on the FPGA.
• I/O Capacity Offers 192 general-purpose I/O pins to interface with peripherals, sensors, and external digital buses.
• Gate Equivalent Approximately 20,000 gates of logic capacity for moderate-complexity digital designs.
• Power Operates from a 3 V to 3.6 V supply range, enabling compatibility with common 3.3 V system rails.
• Package & Mounting Supplied in a 240-BFQFP package (supplier device package: 240-PQFP, 32×32) for surface-mount PCB assembly.
• Industrial Temperature Range Rated for operation from –40 °C to 100 °C to meet industrial-environment requirements.
• Regulatory RoHS-compliant for reduced hazardous substance content.

Typical Applications

• Industrial Control — Implement custom control logic, sequencing, and interface glue for PLCs, motor controllers, and PLC expansion modules.
• Embedded Interfaces — Bridge and adapt peripheral interfaces, handle data aggregation from sensors, and implement protocol translators.
• Signal Conditioning & Preprocessing — Perform deterministic preprocessing, simple digital filtering, and timing-critical logic ahead of a microcontroller or DSP.

Unique Advantages

• Balanced Logic Density: 1,862 logic elements provide sufficient resources for moderate-complexity custom logic without excessive board area or cost.
• On‑Chip Memory: 25,088 bits of embedded RAM reduce reliance on external memory for small buffers and FIFOs, simplifying BOM and layout.
• High I/O Count: 192 I/Os allow direct connection to many peripherals and sensor arrays, reducing the need for external I/O expanders.
• Industrial Temperature Rating: –40 °C to 100 °C operation supports deployment in harsh or wide-temperature environments.
• Standard 3.3 V Supply: Compatibility with a 3 V to 3.6 V supply range eases integration into common embedded power architectures.
