Field Programmable Gate Array Procurement Notes

Verify the specific suffix codes against official datasheets to confirm temperature range and package variant. Ensure that the procurement channel provides genuine components with traceable origin to avoid counterfeit risks common in legacy FPGA/CPLD markets. Check for RoHS compliance status if required by your manufacturing standards.

Field Programmable Gate Array Selection Notes

Select this component when a low-cost, low-pin-count solution is needed for simple logic functions. Compare against larger CPLDs if future expansion of I/O count or macrocells is anticipated. Consider power consumption differences between 1.8V and 3.3V operation modes during system design.

Field Programmable Gate Array Part Context

This part is part of the Xilinx CoolRunner-II series, designed for cost-sensitive applications requiring moderate complexity. It bridges the gap between discrete logic gates and larger FPGAs, offering a balance of performance, pin count, and ease of use for basic digital control tasks.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements may be limited due to proprietary architecture. Evaluate equivalent parts from Lattice Semiconductor or Microchip Technology with similar macrocell counts and I/O configurations. Verify software toolchain compatibility before substitution.
