XCS40-4BG256C

The XCS40-4BG256C is a Spartan® Field Programmable Gate Array (FPGA) IC manufactured by AMD, provided in a 256-BBGA package (256-PBGA, 27×27). The device integrates 1,862 logic elements, approximately 40,000 gates and 25,088 bits of on-chip RAM, with 205 user I/O pins for configurable system designs.

Specified for commercial-grade applications, the XCS40-4BG256C operates from a 4.75 V to 5.25 V supply and across an operating temperature range of 0 °C to 85 °C. The device is surface-mount and RoHS compliant.

Key Features

• Core Logic 1,862 logic elements and approximately 40,000 gates provide a moderate-density programmable fabric for implementing combinational and sequential logic.
• Embedded Memory 25,088 bits of on-chip RAM support small buffers, FIFOs and temporary data storage directly within the FPGA fabric.
• I/O Capacity 205 user I/O pins enable connections to multiple peripherals, buses and external devices from a single device.
• Power Single-supply operation from 4.75 V to 5.25 V simplifies integration into 5 V system environments.
• Package & Mounting 256-BBGA (supplier package: 256-PBGA, 27×27) in a surface-mount form factor supports compact PCB layouts.
• Temperature & Grade Commercial grade operation from 0 °C to 85 °C for standard commercial electronics applications.
• Environmental Compliance RoHS compliant to meet common environmental and materials requirements.

Typical Applications

• Embedded Control and Glue Logic Implement custom control functions and interface logic using the device’s logic elements and abundant I/O.
• Prototyping and Development Use the FPGA’s reprogrammable fabric and on-chip RAM for design validation and iterative development.
