LA4032V-75TN48E

Overview

The LA4032V-75TN48E is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V/Z family. It features 32 macrocells and supports up to 32 user I/Os within a 48-pin TQFP package. The device operates with a 1.8 V core voltage, enabling low dynamic power consumption while maintaining SuperFAST performance. It offers a maximum propagation delay of 7.5 ns and a maximum operating frequency of 168 MHz. Designed for automotive applications, it meets AEC-Q100 standards and functions across an extended temperature range of -40°C to +125°C.

Feature Summary

• Automotive Grade: Certified to AEC-Q100 standards for reliability in vehicle environments.
• Extended Temperature Range: Operates reliably from -40°C to +125°C junction temperature.
• Low Power Architecture: Utilizes a 1.8 V core voltage to minimize dynamic power dissipation.
• High Performance: Delivers SuperFAST timing with a maximum frequency of 168 MHz.

Applications

• Automotive infotainment systems
• Vehicle sensor interface logic
• Body control modules
• Industrial automation controllers

Procurement Notes

Verify the specific suffix 'E' against official Lattice documentation to confirm its impact on packaging or material composition, as distributor listings may vary in describing ordering suffixes. Ensure compliance with RoHS directives and check Moisture Sensitivity Level (MSL) ratings prior to surface mount assembly processes.

Selection Notes

Select this component when automotive qualification (AEC-Q100) and wide temperature operation are required alongside moderate logic density. Compare against the LC4032V series if industrial grade (0°C to 90°C) is sufficient, as the LA variant provides broader thermal resilience. Confirm that the 1.8 V core voltage aligns with the system's power budget and I/O interface requirements.

Part Context

This part belongs to the ispMACH 4000V/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The family is characterized by Global Routing Pool technology for predictable timing and pin-out retention. The LA prefix specifically denotes the automotive-grade version of the standard LC series CPLDs.

Replacement Considerations

The LC4032V-75TN48C is a functionally similar industrial-grade alternative within the same package but lacks AEC-Q100 certification and the extended -40°C to +125°C temperature range. Verify if the automotive qualification is strictly necessary for the target application before substituting.
