Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-10) against design timing requirements, as other variants like -75 exist within the same package. Confirm moisture sensitivity level handling procedures during assembly, as the component is humidity sensitive. Ensure the TQFP-128 footprint matches the PCB layout exactly. Check for RoHS compliance status on the latest manufacturer documentation before finalizing procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 92 I/Os are required in a TQFP-128 package. Compare the 10 ns propagation delay against system timing constraints; faster variants like LC4128V-5 or slower ones like LC4128V-15 may offer cost or power trade-offs. Consider the LC4128C variant if commercial temperature range suffices. Verify power consumption specifications against thermal management capabilities.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000V family, designed for high-density, low-power CPLD applications. It utilizes non-volatile Flash technology, allowing instant-on functionality without external configuration memory. The family supports multiple voltage domains (3.3V, 2.5V, 1.8V) and offers flexible I/O standards, making it suitable for mixed-signal interfaces and legacy system integration.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes include other speed grades within the LC4128V series, such as LC4128V-5TN128I or LC4128V-15TN128I, provided timing margins allow. The LC4128C-75TN128I is a pin-compatible alternative but differs in temperature rating and performance characteristics. Verify that any substitute maintains the same TQFP-128 package and pinout compatibility.
