LC4032V-75T44E

Overview

The LC4032V-75T44E is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V 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 and a maximum operating frequency of 168 MHz. It is designed for industrial temperature ranges, functioning between -40°C and +125°C. The architecture utilizes EEPROM technology for non-volatile configuration storage.

Feature Summary

• 32 Macrocells with 30 User I/Os in a 44-pin TQFP package
• Maximum propagation delay of 7.5 ns and operating frequency of 168 MHz
• EEPROM-based non-volatile memory for system-in-programmability
• Industrial temperature range operation from -40°C to +125°C

Applications

• General-purpose digital logic replacement
• Bus protocol conversion and interface bridging
• Address decoding and control logic generation

Procurement Notes

Verify the specific suffix 'T44E' against official Lattice documentation to confirm pinout compatibility and package dimensions. Ensure design files match the exact variant, as suffixes may indicate minor manufacturing or marking changes without altering core functionality. Cross-reference with the LA4032V series if automotive qualification data is required.

Selection Notes

Select this component when a low-density CPLD with EEPROM persistence is needed for moderate speed applications requiring 32 macrocells. Compare against the LA4032V-75TN44E if AEC-Q100 automotive qualification is necessary, as the standard V-series may not meet those specific reliability standards. Verify power consumption requirements against the 12 mA typical operating current.

Part Context

This part belongs to the Lattice ispMACH 4000V family, which provides high-density logic in small packages. It serves as a successor to older GAL and PAL devices, offering reprogrammability via JTAG. The 4000V series is characterized by its fast propagation delays and support for both 1.8V and 3.3V I/O interfaces.

Replacement Considerations

The LA4032V-75TN44E is a verified equivalent within the same family, potentially offering automotive-grade qualification. Other members of the 4000V series, such as the LC4064V, offer higher density but require pinout verification.
