Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and speed grade. Confirm that the component meets all required environmental specifications for the intended application environment. Check for any recent revisions to the datasheet that may impact pin compatibility or electrical characteristics.

Field Programmable Gate Array Selection Notes

Select this device for applications requiring low-density programmable logic with non-volatile configuration. Ensure the design utilizes the available embedded memory resources efficiently. Verify that the I/O voltage requirements match the system's power supply rails. Consider the thermal performance if operating at maximum frequency or temperature limits.

Field Programmable Gate Array Part Context

This part belongs to the Lattice MachXO family, which combines CPLD-like instant-on capabilities with FPGA flexibility. The MachXO series is designed for cost-sensitive, low-power applications traditionally served by CPLDs or small FPGAs. It offers high integration through embedded memory and PLLs.

Field Programmable Gate Array Replacement Considerations

Direct replacements within the MachXO family include LCMXO2280C-3FTN256I and LCMXO2280E-4B256I, subject to speed grade and commercial/industrial temperature range availability. Cross-family migration to MachXO2 or MachXO3 requires careful review of pinout and feature differences.
