XCS20XL-4PQ208C

Field Programmable Gate Array Overview

The XCS20XL-4PQ208C is a field-programmable gate array (FPGA) from the Spartan-XL family, manufactured by AMD/Xilinx. It features 784 configurable logic blocks and approximately 13,000 system gates. The device supports a maximum operating frequency of 250 MHz and operates within a supply voltage range of 3.0 V to 3.6 V, with a nominal rating of 3.3 V. It utilizes a 208-pin plastic quad flat package (PQFP) with fine pitch terminals. The component is designed for surface-mount installation and functions within an ambient temperature range of 0°C to +85°C.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' corresponds to the commercial temperature grade (0°C to +85°C) as defined in the official datasheet. Confirm the package type matches the 208-pin PQFP specification. Check current availability status, as this model may be discontinued or subject to last-time buy notices. Ensure compatibility with existing PCB footprints and soldering profiles for fine-pitch components.

Field Programmable Gate Array Selection Notes

Select this component when a moderate logic density FPGA is required for 3.3V systems. Compare against the standard XCSPARTAN series if lower power consumption is critical, noting that XL variants may have different power characteristics. Verify that the 250 MHz speed grade meets the timing requirements of the target design. Consider the physical dimensions of the PQFP-208 package for board space constraints.

Field Programmable Gate Array Part Context

This part belongs to the Spartan-XL family, which succeeded the original Spartan series. It offers increased logic capacity compared to earlier generations while maintaining pin compatibility with some legacy designs. The XCS20XL variant specifically targets cost-sensitive applications requiring robust programmable logic capabilities without the complexity of higher-end Virtex devices.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are limited due to the discontinued status. Evaluate the XC2S100 or XC2S50 from the Spartan-II family for functional equivalents, though voltage and feature differences exist. Consult AMD's migration guides for architectural changes between Spartan-XL and subsequent families.
