Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix against project timing requirements, as the '10' designation indicates a 10 ns delay variant distinct from faster or slower options. Confirm moisture sensitivity level handling procedures during assembly, as the device requires proper storage conditions. Ensure the TQFP-100 footprint matches the target PCB layout constraints before finalizing procurement orders.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are required for designs exceeding the capacity of lower-density variants like the LC4128V. Choose the TN100I package for surface-mount applications needing 64 accessible I/O pins. The 10 ns speed grade offers a balance between performance and power consumption compared to faster, higher-cost alternatives within the same family.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000V series, designed for high-performance, low-power CPLD applications. The series utilizes non-volatile technology to retain configuration data without external memory. The LC4256V variant specifically targets designs requiring moderate logic density with fast signal processing capabilities in compact packages.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package include other speed grades of the LC4256V series, such as the LC4256V-75TN100I, provided timing margins allow for the adjusted propagation delay. Cross-family migration to newer Lattice CPLD lines may require schematic and layout modifications due to architectural differences.
