LC4128V-75TN144C

Complex Programmable Logic Devices Overview

The LC4128V-75TN144C is a Complex Programmable Logic Device (CPLD) from the ispMACH 4000V family. It features 128 macrocells organized into 8 Logic Array Blocks (LABs) and provides 96 I/O pins. The device operates within a supply voltage range of 3.0 V to 3.6 V, with a maximum propagation delay of 7.5 ns and a maximum operating frequency of 333 MHz. It supports in-system programmability via EEPROM technology and functions across an industrial temperature range of -40°C to +105°C.

Complex Programmable Logic Devices Feature Summary

• Supports in-system programmability using non-volatile EEPROM memory technology for flexible design updates.

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Interface bridging between legacy protocols and modern digital buses
• State machine implementation in embedded communication hardware

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm commercial grade temperature rating and package marking standards. Ensure compatibility with existing PCB footprints for the 144-TQFP package. Confirm that the design toolchain supports the ispMACH 4000V architecture for programming and simulation.

Complex Programmable Logic Devices Selection Notes

Select this component when high-speed performance up to 333 MHz is required alongside moderate logic density. Compare against the LC4128V-75TN144I if industrial temperature ratings (-40°C to +105°C) are necessary, as the 'C' suffix typically denotes commercial range. Evaluate power consumption requirements against the 12 mA typical operating current.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V series, designed for super-fast, high-density PLD applications. It serves as a successor to earlier CPLD generations, offering improved speed and density while maintaining backward compatibility with standard JEDEC pinouts for many packages.

Complex Programmable Logic Devices Replacement Considerations

The LC4128V-5TN144C is a documented alternative within the same family, offering faster 5 ns delay but potentially different electrical characteristics. Verify pinout compatibility and thermal performance before substitution.
