LC4064ZE-7TN100I

Complex Programmable Logic Devices Overview

The LC4064ZE-7TN100I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000ZE family. It features 64 macrocells and supports up to 64 I/O pins within a TQFP-100 package. The device operates on a 1.8V supply voltage with interface compatibility for 3.3V, 2.5V, 1.8V, and 1.5V levels. Key electrical parameters include a maximum propagation delay of 7.5 ns, a maximum operating frequency of 241 MHz, and a typical operating current of 80 uA at 1.8V. It functions within a temperature range of -40°C to +105°C.

• Address decoding and bus arbitration in industrial control units
• State machine implementation for communication protocol controllers
• Logic replacement for legacy discrete components in space-constrained designs

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix against official Lattice documentation, as the provided model number may differ from standard commercial listings which often cite the LC4064ZE-5 variant. Confirm moisture sensitivity level handling requirements prior to assembly. Ensure design tools support the ispMACH 4000ZE architecture for accurate place-and-route results. Cross-reference the manufacturer part number with authorized distributors to avoid obsolete or counterfeit sources.

Complex Programmable Logic Devices Selection Notes

Select this component when low static power consumption is critical alongside moderate logic density. The 1.8V operation distinguishes it from the 3.3V LC4064V series. Consider the 7.5 ns delay specification for timing-critical paths. Evaluate pin-out retention needs against the robust routing pools. Compare against the LC4064ZE-5 variant if higher speed performance is required for the same package footprint.

Complex Programmable Logic Devices Part Context

This CPLD belongs to the ispMACH 4000ZE series, an evolution of the original ispMACH 4000Z architecture. The series emphasizes high speed combined with ultra-low power dissipation. It utilizes a flexible structure with four Logic Array Blocks (LABs). The family is designed for applications requiring reliable programmability and extensive I/O flexibility across various industrial and commercial environments.

Complex Programmable Logic Devices Replacement Considerations

The LC4064ZE-5TN100I serves as a verified faster-speed alternative within the same package and feature set. The older LC4064B-75T100I is discontinued and operates at 2.5V, requiring significant voltage level adjustments. Direct pin-compatible replacements from other manufacturers are not explicitly documented in the provided source material.
