Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'BC' against official Lattice documentation, as standard listings often cite 'C'. Confirm current lifecycle status, as similar LC4256V variants are marked as obsolete or end-of-life in public records. Ensure the FN256 package availability matches design requirements. Cross-reference RoHS compliance details with the latest manufacturer datasheet before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with high speed is required. The 256 macrocell count suits applications needing more capacity than smaller CPLDs but less than FPGAs. Consider the 5ns delay and 322MHz max frequency for timing-critical designs. Verify that the FN256 footprint fits the PCB layout constraints compared to other packages like TQFP.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice LC4000V family, which offers low-power CMOS technology. The LC4256V variant specifically provides 256 macrocells, balancing performance and power consumption. It is designed for general-purpose programmable logic applications where non-volatile configuration and ease of use are prioritized over massive parallel processing capabilities found in larger FPGA families.

Complex Programmable Logic Devices Replacement Considerations

Public sources indicate the LC4256V series may be discontinued. Check for direct pin-compatible upgrades within the Lattice portfolio, such as newer MachXO or CrossLink series devices, though architectural differences exist. Verify if legacy distributors hold remaining stock or if alternative manufacturers offer functionally equivalent CPLDs with matching I/O counts and speeds.
