XC4020XL-2HT144I

The XC4020XL-2HT144I is an AMD field programmable gate array (FPGA) from the XC4000E/X family provided in a 144-LQFP exposed pad package. It delivers a compact, surface-mount programmable logic solution with 1,862 logic elements, approximately 25,088 bits of on-chip RAM and a gate count of 20,000.

Designed for demanding environments, the device operates from a 3.0 V to 3.6 V supply and is specified for industrial temperature operation from −40°C to 100°C. The package provides 113 user I/O pins and an exposed pad for thermal performance in board-level designs.

Key Features

• Core Logic  1,862 logic elements supporting custom digital logic implementations and moderate-density programmable functions.
• Embedded Memory  25,088 bits of on-chip RAM to store configuration data, small buffers, and state information.
• I/O and Gate Count  113 I/O pins and an internal gate count of 20,000 enable a variety of peripheral interfaces and combinational/sequential logic resources.
• Power  Single-supply operation from 3.0 V to 3.6 V suited to standard 3 V systems.
• Package and Mounting  144-LQFP exposed pad package (supplier device package listed as 144-TQFP, 20 × 20 mm) in a surface-mount form factor for compact PCB integration and thermal dissipation.
• Industrial Temperature Grade  Specified to operate from −40°C to 100°C, supporting use in industrial temperature environments.
• RoHS Compliant  Meets RoHS requirements for materials compliance.

Typical Applications

• Industrial control logic  Programmable control and interface tasks that benefit from 1,862 logic elements and an industrial temperature rating (−40°C to 100°C).
• Embedded system prototyping  Board-level prototyping and development where 113 I/O lines and on-chip RAM (25,088 bits) are needed for glue logic and local buffering.
• Peripheral interfacing  Implementing custom I/O adaptation, simple protocol bridging, and interface logic within a compact 144-LQFP surface-mount package.

Unique Advantages

• Balanced logic and memory  Combines 1,862 logic elements with 25,088 bits of embedded RAM to support moderate-density programmable designs without external memory for small buffers.
• Wide I/O capability  113 I/O pins provide flexibility for connecting multiple peripherals and interfaces on a single device.
• Industrial-rated operation  −40°C to 100°C operating range and an industrial grade designation make the device suitable for extended-temperature environments.
• Compact, thermally aware package  144-LQFP exposed pad (surface mount) supports compact PCB layouts and improved thermal dissipation for sustained operation.
• Standard 3 V supply  Operates from 3.0 V to 3.6 V, matching common system power rails for straightforward integration.
• Regulatory compliance  RoHS-compliant construction simplifies material compliance considerations.
