LA4064ZC-75TN100E

Overview

The LA4064ZC-75TN100E is an automotive-grade Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000Z family. It features 64 macrocells organized into 4 Logic Array Blocks (LABs) and provides 64 I/O pins in a TQFP-100 package. The device operates at a maximum frequency of 168 MHz with a maximum propagation delay of 7.5 ns. It supports a supply voltage range of 1.7 V to 1.9 V, typically 1.8 V, and meets AEC-Q100 Grade 1 qualification for operation between -40°C and +125°C.

Feature Summary

• Automotive qualified under AEC-Q100 standards for high reliability
• High performance with 168 MHz max frequency and 7.5 ns propagation delay
• Low power architecture supporting 1.8V core voltage
• In-system programmable via JTAG interface

Applications

• Automotive infotainment systems
• Body control modules
• Telematics units
• Sensor interface logic

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm environmental compliance status, as suffixes can indicate RoHS or lead-free variations. Confirm the package type is TQFP-100 and ensure the design accounts for the 1.8V core voltage requirement rather than standard 3.3V logic levels found in other series members.

Selection Notes

Select this component when automotive certification (AEC-Q100) is mandatory for the application. Compare against the LC4064ZC-75TN100E if industrial temperature range (-40°C to +85°C) is sufficient, as it may offer different availability or pricing dynamics. Ensure the system power budget accommodates the dynamic current consumption typical of CPLDs at 168 MHz switching speeds.

Part Context

This part belongs to the ispMACH 4000Z family, which utilizes Lattice's low-voltage CMOS technology. Unlike the LA4064V series which often supports 3.3V, the Z-series is optimized for lower voltage operations around 1.8V, providing better power efficiency for modern automotive electronics while maintaining high density and speed.

Replacement Considerations

Direct pin-compatible replacements within the same automotive grade include other parts from the LA4064ZC series with different package options (e.g., TN44, TN48) if I/O count allows. Non-automotive equivalents like the LC4064ZC-75TN100I share electrical characteristics but lack AEC-Q100 certification.
