LA4064V-75TN44E

Overview

The LA4064V-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 (LABs) and provides 30 I/O pins in a TQFP-44 surface-mount package. The device operates at a supply voltage of 3.0 V to 3.6 V with a typical current of 12 mA. Key electrical specifications include a maximum propagation delay of 7.5 ns and a maximum operating frequency of 168 MHz. It is qualified under AEC-Q100 standards and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• AEC-Q100 Grade 1 qualification for automotive reliability
• 64 Macrocells with 4 LABs and 30 I/Os
• 7.5 ns maximum propagation delay
• Extended industrial temperature range (-40°C to +125°C)

Applications

• Automotive electronic control units
• In-vehicle networking interfaces
• Sensor signal conditioning

Procurement Notes

Verify the specific suffix 'E' against official Lattice documentation to confirm it denotes the automotive grade and lead-free status as indicated by the AEC-Q100 qualification. Ensure the TQFP-44 package dimensions match the target PCB footprint requirements. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this component when an automotive-certified CPLD with low pin count is required. Compare against the LC4064V series if higher performance (400 MHz) is needed but automotive qualification is not mandatory. Verify that the 64 macrocell density meets logic capacity needs without requiring larger packages like the TN100 variant.

Part Context

This part belongs to the Lattice ispMACH 4000V family, which offers system-in-package programmability. The 'LA' prefix typically indicates the automotive-grade variant within the 4000V line, distinguishing it from the standard commercial LC series. It serves as a drop-in replacement for legacy GAL devices in automotive applications requiring reprogrammability.

Replacement Considerations

The LC4064V-75TN44I is a commercial-grade alternative with identical pinout and logic structure but lacks AEC-Q100 certification and has a lower maximum operating temperature (+105°C). Designers must verify environmental constraints before substituting.
