LC4064V-75TN44C

Complex Programmable Logic Devices Overview

The LC4064V-75TN44C is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4000V family. It features 64 macrocells organized into 4 Logic Array Blocks (LABs) and provides 30 user I/O pins. The device operates at a supply voltage of 3.0 V to 3.6 V, with a typical operating voltage of 3.3 V. It supports a maximum frequency of 400 MHz and has a maximum propagation delay of 7.5 ns. The component is housed in a 44-pin TQFP package and is rated for an industrial temperature range of -40°C to +105°C.

Complex Programmable Logic Devices Feature Summary

• High-performance architecture supporting up to 400 MHz operation with 7.5 ns max propagation delay.
• Non-volatile EEPROM technology allowing unlimited reprogramming without external configuration memory.
• System-in-Package (SiP) compatibility with full support for In-System Programming (ISP).
• Industrial temperature range (-40°C to +105°C) suitable for demanding environments.

Complex Programmable Logic Devices Applications

• Interface bridging between different logic families or voltage domains.
• Address decoding and chip select generation in embedded systems.
• State machine implementation for control logic.
• Glue logic replacement in legacy system upgrades.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm it denotes the commercial temperature variant (0°C to 70°C) rather than the industrial variant ('I'). Datasheets often list the 'I' grade as standard; ensure the requested part matches the thermal requirements of the target application before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. Compare the 400 MHz speed grade against the slower 75 ns variants if performance is not critical. Ensure the 44-pin TQFP footprint fits the PCB layout constraints. Verify that the 3.3 V I/O levels match the connected components.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, which succeeded the ispMACH 4000B series. It offers higher density and speed compared to earlier generations while maintaining low power consumption. The 'V' indicates the specific product generation within the 4000 series lineage.

Complex Programmable Logic Devices Replacement Considerations

The LC4064V-75TN44I is the industrial temperature version of this device. If the application requires operation below 0°C, the 'I' suffix part must be used instead. Other pin-compatible options exist within the same package but may differ in speed or cell count.
