Complex Programmable Logic Devices Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Lattice Semiconductor. Verification of availability should focus on secondary market distributors or surplus suppliers. Designers must confirm the authenticity of stock and check for potential lead time variations associated with end-of-life inventory. Alternative sourcing strategies are recommended for new production runs.

Complex Programmable Logic Devices Selection Notes

Select this device when a high pin count CPLD with moderate speed is required. The 7.5 ns delay suits applications where timing margins allow for slower switching than modern FPGAs. Consider the 256-pin footprint for board space constraints. Verify that the 0°C to 90°C industrial temperature range meets environmental requirements, as it differs from the wider -40°C to 85°C range found in some other CPLD families.

Complex Programmable Logic Devices Part Context

Part of the ispMACH 4000V family, designed for cost-effective, high-density logic solutions. This series bridges the gap between standard CPLDs and low-end FPGAs, offering non-volatile configuration without the complexity of FPGA flow tools. It targets applications requiring reliable, instant-on operation with significant logic density in a compact form factor.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitutes include the LC4384V-75FTN256I from Lattice Semiconductor and the T13F256I4 from Efinix. These alternatives offer similar pin counts and functionality but may differ in specific electrical characteristics or software toolchain compatibility. Evaluate pin-to-pin compatibility and logical equivalence before substitution.
