LA4032V-75TN44E

Overview

The LA4032V-75TN44E is an automotive-grade Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V/Z Auto family. It features 32 macrocells and supports up to 30 user I/Os within a 44-pin TQFP package. The device operates on a 3.3 V supply voltage with a maximum propagation delay of 7.5 ns. Certified under AEC-Q100 standards, it ensures reliability for automotive applications across an extended temperature range of -40°C to +125°C.

Feature Summary

• AEC-Q100 qualified for automotive grade reliability
• Supports JTAG In-System Programming (ISP)
• 5 V tolerant I/Os compatible with LVCMOS 3.3, LVTTL, and PCI interfaces
• Low power consumption with 1.8 V core voltage

Applications

• Automotive electronic control units (ECUs)
• In-vehicle infotainment systems
• Body electronics and lighting control modules

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official documentation to confirm if it denotes a specific environmental compliance or packaging variation distinct from standard industrial grades. Ensure the design accounts for the 44-TQFP footprint dimensions and moisture sensitivity level requirements during assembly.

Selection Notes

Select this component when automotive qualification (AEC-Q100) is mandatory for the target application. Compare against the LC4032V-75TN44I variant if the operating environment does not require the extended -40°C to +125°C temperature range, as the industrial version may offer different availability or cost structures while maintaining similar electrical performance.

Part Context

This part belongs to the ispMACH 4000V/Z Auto family, which integrates high-density logic with low-power architecture. The family blends ispLSI 2000 and ispMACH 4A technologies to provide SuperFAST performance. The LA4032V variant specifically targets the lower density segment of the automotive CPLD market, offering a balance of pin count and logic resources.

Replacement Considerations

The LC4032V-75TN44I serves as the industrial-grade equivalent with identical logical functionality but a restricted operating temperature range of 0°C to +90°C. Direct substitution requires verifying that the system thermal design remains within the industrial limits.
