LC4032V-75TN48E

Overview

The LC4032V-75TN48E is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 32 macrocells and supports up to 32 user I/Os within a 48-pin TQFP package. The device operates at a maximum frequency of 400 MHz with a typical propagation delay of 7.5 ns. It utilizes non-volatile EEPROM technology for configuration storage, allowing for in-system programmability. The standard commercial grade variant typically operates between 0°C and +90°C on a 3.3V supply.

Feature Summary

• 32 Macrocells with 32 User I/Os
• 400 MHz Maximum Operating Frequency
• 7.5 ns Typical Propagation Delay
• EEPROM Non-Volatile Configuration Memory

Applications

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

Procurement Notes

Verify the suffix 'E' against official Lattice documentation to confirm if it denotes an automotive-grade qualification or specific environmental rating, as standard commercial parts typically use suffix 'C'. Confirm moisture sensitivity level and reflow soldering profile requirements prior to assembly.

Selection Notes

Select this component when a low pin-count CPLD with fast switching speeds is required. Ensure the design fits within the 32 macrocell limit. Compare against the LA4032V series if automotive temperature ranges (-40°C to +125°C) are necessary, as the 'V' series often has specific industrial variants.

Part Context

This part belongs to the Lattice ispMACH 4000V family, designed for high-performance applications requiring small form factors. It serves as a successor to older GAL devices, offering reprogrammability and higher density than discrete logic solutions while maintaining low power consumption.

Replacement Considerations

Direct pin-compatible replacements include other members of the ispMACH 4000V family such as the LC4032V-75TN48C (commercial grade). Verify that any substitute matches the 7.5 ns speed grade and 3.3V I/O voltage levels.
