LC4064V-10T100I

Complex Programmable Logic Devices Overview

The LC4064V-10T100I is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 64 macrocells organized into four Logic Array Blocks (LABs) and provides 64 I/O pins in a TQFP-100 package. The device supports system-in-programmability via EEPROM technology and operates at supply voltages of 3.3 V, 2.5 V, or 1.8 V. Key electrical parameters include a maximum operating frequency of 400 MHz, a typical propagation delay of 2.5 ns, and an operating temperature range of -40°C to +105°C for the industrial grade variant.

Complex Programmable Logic Devices Feature Summary

• High-performance architecture with up to 400 MHz maximum operating frequency and 2.5 ns propagation delay.
• Supports multiple voltage domains including 3.3 V, 2.5 V, and 1.8 V for flexible interface compatibility.
• Features 64 macrocells across 4 LABs with up to 80 product terms per output.
• Enables in-system programming and JTAG boundary scan support.

Complex Programmable Logic Devices Applications

• Industrial control systems requiring high-density logic in compact packages.
• Communication interfaces and protocol conversion circuits.
• General-purpose digital logic replacement for discrete components.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'T' against the manufacturer's official datasheet to confirm package type and temperature grade, as variations exist within the LC4064V series. Ensure design compliance with the specified 3.3 V/2.5 V/1.8 V supply requirements and check for moisture sensitivity level handling during assembly.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with fast switching speeds is required. Compare against the LC4064C or LC4064Z variants if different temperature ranges or voltage options are needed. Confirm that the 100-pin TQFP footprint fits the PCB layout constraints and that the 64 I/O count meets the interface requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, designed for high-density applications. It serves as a successor to earlier GAL-based designs, offering reprogrammability and higher performance. The LC4064V series is distinct from the FPGA families like iCE40, focusing on deterministic combinatorial and registered logic.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include LC4064V-75TN100I or LC4064V-25TN100I, depending on speed grade requirements. Verify that any substitute maintains the same TQFP-100 package and EEPROM programming mechanism.
