LC4064ZC-37T48C

Complex Programmable Logic Devices Overview

The LC4064ZC-37T48C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000Z family. It features 64 macrocells and supports up to 32 I/Os in a TQFP-48 package. The device operates at a maximum frequency of 333 MHz with a typical propagation delay of 2.7 ns. It utilizes a 1.8V core voltage for low dynamic power consumption while maintaining 5V-compatible I/Os. The component is designed for high-density, superfast performance applications requiring system-in-programmability via JTAG.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (e.g., -37 vs -5) against the manufacturer's datasheet to ensure timing requirements are met. Confirm RoHS compliance status as it varies by manufacturing batch and region. Check for end-of-life or obsolescence notices directly from Lattice Semiconductor before procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the logic density. The -37 speed grade offers a balance between performance and power. Ensure the design requires 5V I/O compatibility if interfacing with legacy systems. Compare against the LC4064ZE series if lower power is prioritized over maximum speed.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000Z family, which integrates SuperFast architecture with non-volatile configuration memory. It replaces older GAL and PAL devices in designs requiring reprogrammability and higher complexity. The Z variant specifically denotes non-volatile technology within the 4000 series.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements include other speed grades within the LC4064ZC series, such as LC4064ZC-5T48I or LC4064ZC-7T48I, provided timing constraints allow. Verify that the replacement's I/O standards and power specifications match the original design requirements.
