LC4064V-75TN100I

Complex Programmable Logic Devices Overview

The LC4064V-75TN100I 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 64 I/O pins in a TQFP-100 surface-mount package. The device operates at a supply voltage of 3.3 V, with a range of 3.0 V to 3.6 V. Key electrical specifications include a maximum propagation delay of 7.5 ns and a maximum operating frequency of 400 MHz. It supports an industrial temperature range from -40°C to +105°C and draws approximately 12 mA of operating current.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells distributed across 4 Logic Array Blocks for high-density logic implementation
• 7.5 ns maximum propagation delay supporting high-speed digital applications
• Industrial temperature rating (-40°C to +105°C) for robust environmental operation
• TQFP-100 package with 64 accessible I/O pins

Complex Programmable Logic Devices Applications

• High-density programmable logic replacement for legacy PLDs
• Interface bridging between different voltage domains or protocols
• State machine implementation in industrial control systems
• Address decoding and bus arbitration in embedded designs

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized Lattice distributors or certified suppliers. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity handling requirements prior to assembly. Ensure the specific suffix TN100I matches the required package and temperature grade for the target application.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. The 7.5 ns speed grade is suitable for moderate-to-high frequency logic. Compare against the LA4064V series if automotive AEC-Q100 qualification is required instead of standard industrial ratings. Ensure the TQFP-100 footprint fits the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, which succeeded the older LC4064B series. The 'V' denotes the enhanced voltage and performance variant. It serves as a drop-in logical upgrade for many legacy CPLD designs requiring higher density and faster switching speeds within the same pin count.

Complex Programmable Logic Devices Replacement Considerations

The LC4064B-75T100I is a predecessor but may be discontinued. Verify pin compatibility and electrical differences before substitution. No direct cross-model functional equivalents are listed in public data; FPGA alternatives require significant design re-architecture.
