LC4384C-5TN176C

Complex Programmable Logic Devices Overview

The LC4384C-5TN176C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V/C family. It features 384 macrocells and supports up to 128 I/O lines with four dedicated inputs. The device operates at a maximum clock frequency of 156 MHz and utilizes a 176-pin Low-profile Quad Flat Package (LFQFP). Key electrical specifications include system-in-programmability capabilities, JTAG boundary scan support, and compliance with lead-free and RoHS standards.

Complex Programmable Logic Devices Feature Summary

• High-density architecture with 384 macrocells for complex logic implementation
• SuperFast performance supporting a maximum frequency of 156 MHz
• System-in-programmability (ISP) via JTAG interface for flexible updates
• 176-pin LFQFP package providing 128 I/O lines

Complex Programmable Logic Devices Applications

• General-purpose programmable logic control systems
• Interface bridging between different voltage domains or protocols
• Address decoding and bus arbitration in embedded systems

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' corresponds to the commercial temperature grade as defined in the official Lattice datasheet. Confirm that the 176-pin LFQFP package dimensions match the design footprint requirements. Ensure the component meets the required environmental certifications such as RoHS and lead-free status before integration into the final assembly process.

Complex Programmable Logic Devices Selection Notes

Select this model when a design requires moderate logic density with high pin counts in a surface-mount QFP package. The 384 macrocell count suits applications needing extensive combinational and sequential logic without the complexity of an FPGA. Consider the 156 MHz speed grade if timing constraints exceed those of slower CPLD alternatives.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000V/C series, which integrates SuperFast technology for high-speed operation. The 'C' designation typically indicates the commercial temperature range variant within this product line. It serves as a non-volatile logic solution offering deterministic timing and low static power consumption compared to volatile logic devices.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements within the same family include the LC4384C-5TQ144C or LC4384C-5FT256C, depending on whether a smaller QFP or larger BGA package is preferred while maintaining identical logic resources.
