Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms industrial or extended temperature ratings if required, though datasheets typically classify this package variant under commercial ranges unless explicitly stated otherwise. Confirm RoHS compliance status as manufacturing processes evolve. Check for end-of-life notifications or obsolescence notices from Lattice Semiconductor before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select the LC4384C-5T176I when 384 macrocells are sufficient for the design complexity and a TQFP-176 footprint is preferred for through-hole or standard surface-mount assembly. Ensure the system power budget accommodates the 1.8V core voltage and verify that the 156 MHz speed grade meets timing requirements for the target clock domains.

Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4000ZE family, which focuses on ultra-low power consumption while maintaining high performance. The family offers flexibility with multiple package options and temperature grades, allowing designers to scale logic density from 32 to 256 macrocells across different form factors.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same family include other variants of the LC4400 series or LC4384C devices with different speed grades or package types, provided the logic capacity and I/O count remain compatible.
