Complex Programmable Logic Devices Procurement Notes

This component is identified as obsolete or end-of-life by major distributors. Verification of current availability requires direct consultation with authorized Lattice Semiconductor channels or approved secondary market suppliers. Designers should confirm lead times and authenticity rigorously due to the discontinued status.

Complex Programmable Logic Devices Selection Notes

Select this part when existing designs require a drop-in replacement for older CPLDs with similar pin counts and logic density. Ensure the target application does not demand higher performance metrics than the 156 MHz operating frequency allows. Verify that the 3.3V supply voltage aligns with the system power rails before integration.

Complex Programmable Logic Devices Part Context

Part of the ispMACH 4000V series, designed for low-power applications requiring moderate logic capacity. This family bridges the gap between simple programmable logic and complex FPGAs, offering deterministic timing and instant-on capabilities suitable for cost-sensitive consumer and industrial electronics.

Complex Programmable Logic Devices Replacement Considerations

No public confirmed substitutes are listed in the provided documentation. Engineers must evaluate newer Lattice families such as the MachXO series or CrossLink-NX for functional equivalents, ensuring compatibility with existing PCB footprints and design toolchains.
