LC4384B-75TN176I

Complex Programmable Logic Devices Overview

The LC4384B-75TN176I is a high-density, in-system programmable complex PLD from the Lattice CPLD family. It features 4096 usable macrocells and supports supply voltages of 3.3V, 2.5V, and 1.8V. The device operates at a maximum frequency of 75 MHz (indicated by the -75 speed grade) and is housed in a 176-pin TQFP package. Designed for industrial and commercial applications, it provides robust logic density with low power consumption characteristics typical of Lattice's CPLD portfolio.

Complex Programmable Logic Devices Feature Summary

• 4096 usable macrocells for high-density logic implementation
• In-system programmability via JTAG or serial configuration
• Multi-voltage support: 3.3V, 2.5V, and 1.8V I/O standards
• 176-pin Thin Quad Flat Package (TQFP) with 0.5 mm pitch

Complex Programmable Logic Devices Applications

• System control and address decoding
• Interface bridging between different voltage domains
• State machine implementation in industrial equipment
• Memory interface buffering

Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'I' indicates industrial temperature range (-40°C to +85°C). Confirm the package type TN176 corresponds to the 176-pin TQFP. Ensure the design tool suite supports the specific CPLD architecture for programming and simulation.

Complex Programmable Logic Devices Selection Notes

Select this model when 4096 macrocells are required for complex logic functions. Compare against lower-density variants like LC4256 if fewer resources suffice. Consider the -75 speed grade for timing requirements up to 75 MHz. Verify I/O voltage compatibility with connected components.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice CPLD family, distinct from their FPGA lines such as MachXO or ECP series. CPLDs offer deterministic timing and non-volatile configuration, making them suitable for boot control and simple logic tasks where FPGA flexibility is unnecessary.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same family include other LC4384B variants with different speed grades or package options. Cross-family migration to newer Lattice devices may require schematic and code adaptation due to architectural differences.
