XC4020XL-1BG256C

The XC4020XL-1BG256C is a commercial-grade Field Programmable Gate Array (FPGA) from the XC4000E/X family in a 256-BBGA package. It provides a balance of programmable logic capacity, on-chip memory, and I/O density for embedded and digital designs that require customizable logic implementation.

This device targets applications that need moderate logic density and flexible interfacing while operating within standard commercial temperature and supply ranges.

Key Features

• Logic Capacity  Provides 1,862 logic elements to implement custom digital logic and finite-state machines.
• Embedded Memory  Includes 25,088 total on-chip RAM bits—approximately 0.025 Mbits of embedded memory—for small buffers, FIFOs, and storage blocks.
• I/O Density  Offers 205 user I/O pins to support multiple parallel interfaces and peripheral connections.
• Gate Equivalency  Rated at 20,000 gates for quick reference when comparing device density.
• Power  Operates from a supply voltage range of 3 V to 3.6 V to match common digital power rails.
• Package and Mounting  Supplied in a 256-BBGA package (supplier device package: 256-PBGA, 27×27) with surface-mount mounting for compact board integration.
• Operating Range  Commercial temperature grade with an operating range of 0 °C to 85 °C.
• Compliance  RoHS compliant indicating conformance with restricted substances requirements.

Typical Applications

• Custom Digital Logic  Implement programmable state machines, glue logic, and application-specific digital functions using on-chip logic and memory.
• Peripheral Interfacing  Use the device's 205 I/O pins to interface sensors, displays, or external controllers requiring parallel or multiplexed signals.
• Prototyping and Development  Employ the XC4020XL-1BG256C for proof-of-concept designs and early hardware validation where reconfigurability is required.
• I/O Expansion and Glue Logic  Deploy as an I/O expander or protocol adapter to consolidate board-level logic and reduce discrete components.

Unique Advantages

• Balanced Logic and Memory:  1,862 logic elements coupled with 25,088 bits of RAM enable a mix of control logic and modest on-chip storage without external memory.
• High I/O Count:  205 I/O pins allow multiple interfaces and parallel signals to be routed directly to the FPGA, simplifying board-level routing.
• Standard Supply Compatibility:  3 V to 3.6 V supply range aligns with common digital power rails for straightforward power design.
• Compact Surface-Mount Package:  256-BBGA / 256-PBGA (27×27) packaging supports high-density PCB designs while maintaining manufacturability with surface-mount assembly.
• Commercial Temperature Rating:  Rated 0 °C to 85 °C for general-purpose, commercial deployments.
• RoHS Compliant:  Compliant status simplifies environmental and regulatory considerations for many markets.
