XCS20XL-5VQ100C

The XCS20XL-5VQ100C is a Spartan®-XL field programmable gate array (FPGA) from AMD intended for commercial embedded designs. It provides on-chip programmable logic, I/O, and embedded memory suitable for control, interface, and custom-logic applications that require a mid-density FPGA in a compact surface-mount package.

With 950 logic elements, 77 I/O pins and approximately 12.8 Kbits (≈0.0128 Mbits) of embedded RAM, this device targets applications where moderate gate count, flexible I/O and a 100-pin TQFP footprint are defining requirements.

Key Features

• Core Logic  950 logic elements providing approximately 20,000 gates of implementable logic for custom digital functions and glue logic.
• Embedded Memory  Approximately 12.8 Kbits (≈0.0128 Mbits) of on-chip RAM to support small buffers, FIFOs and state storage without external memory.
• I/O Density  77 general-purpose I/O pins to support multiple interfaces, peripheral control and sensor/connectivity routing in a single device.
• Power and Supply  Operates from a 3.0 V to 3.6 V supply range to match common commercial logic power rails.
• Package and Mounting  Surface-mount 100-TQFP package (supplier device package: 100‑VQFP, 14×14 mm) for compact PCB integration and standard assembly processes.
• Operating Range and Compliance  Commercial-grade operation from 0 °C to 85 °C and RoHS-compliant construction for regulatory and environmental considerations.

Typical Applications

• Embedded Control  Implement custom control logic and interface handling where moderate logic density and ample I/O are required.
• Prototyping and Development  Use as a mid-density FPGA platform for validating digital designs and early-stage system integration.
• Glue Logic and Bus Bridging  Replace discrete logic with programmable gates to simplify board routing and consolidate functions into one device.
• Interface Concentration  Aggregate multiple peripheral signals and manage simple protocol translation using available I/O and embedded RAM.

Unique Advantages

• Balanced Logic Density:  950 logic elements and ~20,000 gates provide a middle ground between low-density PLDs and larger FPGAs for cost-effective integration.
• Integrated Memory:  Approximately 12.8 Kbits of on-chip RAM reduces reliance on external memory for small buffers and control state.
• Generous I/O Count:  77 I/O pins support multi-peripheral designs and simplify board-level signal routing.
• Commercial Temperature Range:  Rated 0 °C to 85 °C for standard commercial deployments and typical indoor or controlled-environment applications.
• Compact Surface-Mount Footprint:  100-TQFP (100‑VQFP, 14×14 mm) package enables space-efficient PCB layouts and standard assembly processes.
• Regulatory Consideration:  RoHS-compliant construction supports environmental compliance requirements.

Why Choose XCS20XL-5VQ100C?
