LC4064V-75TN44E

Complex Programmable Logic Devices Overview

The LC4064V-75TN44E is an automotive-grade Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 64 macrocells organized into 4 Logic Array Blocks and provides 30 I/O pins within a 44-pin TQFP package. The device operates at a supply voltage of 3.0 V to 3.6 V with a typical current consumption of 12 mA. It supports a maximum operating frequency of 168 MHz and exhibits a maximum propagation delay of 7.5 ns. Certified under AEC-Q100, it functions reliably across a temperature range of -40°C to +125°C.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TN44E' against official Lattice documentation to confirm the exact pinout and packaging specifications. Ensure that the AEC-Q100 qualification status is explicitly stated in the manufacturer's datasheet for this specific part number before integration into automotive designs. Cross-reference the lead time and production status directly with authorized distributors.

Complex Programmable Logic Devices Selection Notes

Select the LC4064V-75TN44E when automotive certification is mandatory and the design requires 64 macrocells with 30 I/Os. Compare the 168 MHz speed grade against the LC4064V-75T44I if higher performance is needed but automotive qualification is not required. Consider the TQFP-44 package constraints for PCB layout and thermal management in enclosed automotive environments.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000V series, which combines non-volatile configuration memory with high-performance CPLD architecture. The 'V' indicates the low-power variant, while the '75' denotes the 7.5 ns speed grade. The 'E' suffix typically refers to environmental or packaging variations within the TQFP form factor.

Complex Programmable Logic Devices Replacement Considerations

The LC4064V-75T44I is a commercial-grade equivalent with identical electrical characteristics but lacks AEC-Q100 certification. Designers requiring automotive qualification must verify that no direct pin-to-pin automotive alternative exists within the same density tier without consulting Lattice's official obsolescence notices.
