XC4020XL-1HT144C

The XC4020XL-1HT144C is an AMD field-programmable gate array (FPGA) supplied in a 144-pin LQFP package with exposed pad. It delivers on-chip programmable logic, I/O flexibility and embedded RAM for commercial electronic designs.

With 1,862 logic elements, 784 configurable logic blocks (CLBs), 25,088 bits of on-chip RAM and 113 user I/O pins, this surface-mount FPGA is suited to designers needing moderate-density programmable logic in a 144-pin footprint, operating from a 3.0 V to 3.6 V supply at commercial temperature ranges.

Key Features

• Core Logic 1,862 logic elements and 784 CLBs provide configurable resources for custom digital functions and glue-logic implementations.
• On-chip Memory Approximately 0.025 Mbits (25,088 bits) of embedded RAM for small buffering, state storage and register file implementations.
• I/O Capacity 113 user I/O pins to support multiple peripheral interfaces and board-level connectivity in mixed-signal systems.
• Gate Count 20,000 gates for mapping a range of combinational and sequential logic designs.
• Package 144-LQFP with exposed pad; supplier device package listed as 144-TQFP (20×20). Surface-mount mounting type simplifies PCB assembly for compact layouts.
• Power and Temperature Operates from 3.0 V to 3.6 V and rated for commercial temperature operation from 0 °C to 85 °C.
• Compliance RoHS compliant for regulatory and environmental conformity.

Typical Applications

• Control and Glue Logic Implement custom control paths, interface bridging and protocol translation between subsystems using the device’s ample logic and I/O.
• Prototyping and Development Use as a development target for validating digital architectures and timing closure in a compact LQFP package.
• Embedded Logic Functions Integrate small on-chip state machines, lookup tables and buffering using the device’s embedded RAM and logic resources.
• Peripheral Interface Handling Manage multiple external interfaces and I/O signals across the 113 available pins for board-level integration.

Unique Advantages

• Balanced Logic Density: 1,862 logic elements and 20,000 gates provide a mid-range capacity suitable for many control and interfacing tasks without excessive board area.
• Integrated Memory: Embedded RAM (25,088 bits) enables local buffering and state retention without additional external memory components.
• Generous I/O Count: 113 user I/Os reduce the need for external expanders when connecting sensors, peripherals or parallel interfaces.
• Commercial Temperature Rating: Rated for 0 °C to 85 °C operation, appropriate for standard commercial electronics and consumer applications.
• RoHS Compliance: Conforms to RoHS requirements for environmentally conscious product designs.
• Standard Surface-Mount Package: 144-LQFP exposed pad (supplier listed as 144-TQFP 20×20) supports compact PCB layouts and common assembly processes.
