XC4020E-4HQ240C

The XC4020E-4HQ240C is a commercial-grade Field Programmable Gate Array (FPGA) IC from AMD's XC4000E/X family supplied in a 240-pin BFQFP package with exposed pad. It provides a compact, surface-mount programmable logic solution with a balance of logic resources, on-chip memory and I/O for embedded digital designs.

With 1,862 logic cells, 784 configurable logic blocks (CLBs), approximately 25 Kbits of on-chip RAM and 193 I/O pins, this device is intended for applications that require a moderate amount of programmable logic, multiple I/O signals and industry-standard 5 V supply operation.

Key Features

• Core Logic  Provides 1,862 logic cells organized into 784 configurable logic blocks (CLBs) for implementing custom digital functions and control logic.
• Embedded Memory  Total on-chip RAM of 25,088 bits (approximately 25 Kbits) to support small data buffers, state machines and lookup tables.
• I/O Capacity  193 general-purpose I/O pins enable broad connectivity for parallel interfaces, buses and external peripherals.
• Gate Complexity  Estimated equivalence of 20,000 gates for assessing integration level within system designs.
• Power and Supply  Standard 5 V supply range with specified operation from 4.75 V to 5.25 V suitable for legacy and mixed-voltage systems that rely on 5 V rails.
• Package & Mounting  240-BFQFP exposed pad package (supplier device package: 240-PQFP, 32×32) in a surface-mount configuration for PCB assembly and thermal conduction through the exposed pad.
• Operating Conditions  Commercial-grade operating temperature range of 0 °C to 85 °C and RoHS-compliant lead-free status for regulatory compatibility.

Typical Applications

• Programmable Logic Prototyping  Use the XC4020E-4HQ240C to validate and iterate custom digital designs that require moderate logic and memory resources.
• I/O-Intensive Interfaces  Leverage 193 I/O pins to implement parallel buses, protocol bridging or custom I/O expansion for embedded systems.
• Embedded Control and Glue Logic  Deploy the device to centralize control functions, state machines and glue logic where a compact FPGA with combined logic and RAM is needed.

Unique Advantages

• Balanced Logic and Memory:  Combines 1,862 logic cells with approximately 25 Kbits of on-chip RAM to implement moderate-complexity digital functions without requiring external memory.
• High I/O Count:  193 I/O pins provide flexibility for connectivity and allow direct interfacing to multiple peripherals and buses, reducing external interface components.
• Standard 5 V Operation:  Designed for systems operating on a 4.75 V to 5.25 V supply, simplifying integration into legacy 5 V platforms.
• Surface-Mount BFQFP with Exposed Pad:  240-pin BFQFP package with exposed pad supports PCB-mounted thermal path and compact board layouts for space-constrained applications.
• Commercial-Grade Reliability:  Specified for 0 °C to 85 °C operation and delivered RoHS-compliant for lead-free assembly processes.

Why Choose XC4020E-4HQ240C?

The XC4020E-4HQ240C occupies a practical position for designers who need a commercial-grade FPGA with a moderate complement of logic, on-chip RAM and a high I/O count in a space-efficient surface-mount package. Its 240-pin BFQFP exposed pad configuration and 5 V supply compatibility make it suitable for systems that require straightforward board-level integration and thermal management.

This device is suitable for engineers and procurement teams targeting mid-level programmable logic implementations—where a balance of logic density, embedded memory and extensive I/O enables consolidation of control, interfacing and glue logic into a single, RoHS-compliant component.
