Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the package designation 'TN176' corresponds to the 176-pin TQFP form factor. Ensure the design toolchain supports the ispMACH 4000ZE architecture for successful configuration file generation.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require moderate logic density with low pin counts. The 1.8V option allows compatibility with lower voltage cores, while the 3.3V option suits traditional interfaces. Compare against the LC4032Z for reduced capacity needs or the LC4256Z for higher density requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000ZE series, designed as a drop-in replacement for older GAL and PAL devices. It offers non-volatile configuration without external boot flash, simplifying board layout compared to volatile FPGA alternatives.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents within the same family include the LC4384B-10TN176C for commercial temperature grades. Cross-family migration may require retiming adjustments due to differences in clock distribution networks.
