XC4020E-4HQ208I

The XC4020E-4HQ208I is a Field Programmable Gate Array (FPGA) IC from AMD designed for programmable digital logic implementations. It provides mid-density programmable resources with a defined logic capacity, on-chip RAM, and a substantial I/O complement, targeting industrial embedded and control applications that require a 5 V-class supply and extended operating temperature range.

Key Features

• Logic Capacity  Provides 1,862 logic elements supporting up to 20,000 equivalent gates for implementing custom digital functions.
• Embedded Memory  Includes approximately 25,088 bits of on-chip RAM for state storage, buffering, and small data tables.
• I/O Resources  Offers 160 general-purpose I/O pins to interface with peripherals, sensors, and external logic.
• Programmable Fabric Structure  Contains 784 logic clusters to organize and synthesize combinational and sequential logic (as specified).
• Power  Operates from a 4.5 V to 5.5 V supply range compatible with 5 V-class systems.
• Package & Mounting  Supplied in a 208-BFQFP exposed pad package (supplier device package: 208-PQFP, 28×28) suitable for surface-mount assembly.
• Industrial Temperature Rating  Rated for operation from -40 °C to 100 °C for use in industrial environments.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Industrial Control  Use in industrial automation where programmable logic and an industrial temperature range (-40 °C to 100 °C) are required for reliable operation.
• Embedded Systems  Implement custom logic functions and control paths using 1,862 logic elements and on-chip RAM to support moderate-complexity embedded designs.
• I/O-Intensive Interfaces  Integrate multiple peripheral signals and external devices using the device’s 160 I/O pins for flexible interfacing.
• Prototyping and Mid-Density Designs  Evaluate and deploy mid-density programmable logic solutions up to approximately 20,000 gates with moderate embedded memory.

Unique Advantages

• Industrial-grade operation: The -40 °C to 100 °C rating supports deployments in demanding temperature environments.
• Substantial I/O availability: 160 I/O pins enable broad external connectivity without additional interface logic.
• Balanced logic and memory: 1,862 logic elements combined with ~25,088 bits of on-chip RAM provide a compact platform for control and data-handling tasks.
• 5 V supply compatibility: 4.5 V to 5.5 V supply range fits designs that use 5 V-class power rails.
• Surface-mount exposed-pad package: 208-BFQFP exposed pad packaging supports thermal management and dense PCB layouts.
• Regulatory readiness: RoHS compliance supports environmentally conscious product requirements.
