LC4064V-10T44I

Complex Programmable Logic Devices Overview

The LC4064V-10T44I is a Complex Programmable Logic Device (CPLD) from Lattice Semiconductor's ispMACH 4000V family. It features 64 macrocells organized into 4 Logic Array Blocks (LABs) and provides 30 I/O pins. The device operates within a supply voltage range of 3.0 V to 3.6 V, with a typical operating voltage of 3.3 V. It supports a maximum operating frequency of 400 MHz and has a maximum propagation delay of 10 ns. The component is housed in a 44-pin TQFP package and functions reliably across an industrial temperature range of -40°C to +105°C.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells distributed across 4 Logic Array Blocks for flexible logic implementation
• Maximum propagation delay of 10 ns supporting up to 400 MHz operation
• Industrial temperature range capability from -40°C to +105°C
• System-in-Package programmability via JTAG interface

Complex Programmable Logic Devices Applications

• High-speed data bus protocol conversion
• Address decoding and control logic generation
• State machine implementation in industrial controllers
• Interface bridging between legacy and modern digital systems

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +105°C). Confirm the 'T44' designation corresponds to the 44-pin Thin Quad Flat Package (TQFP). Ensure compatibility with standard 3.3V logic levels for input/output interfacing. Check for moisture sensitivity level requirements during storage and handling.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. The 10 ns speed grade is suitable for moderate-frequency applications requiring deterministic timing. Compare against the LC4064V-75T44I if faster switching speeds (7.5 ns) are required. Ensure the 44-pin TQFP footprint matches the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000V series, designed for high-density, low-power CPLD applications. It serves as a successor to earlier non-V variants, offering improved performance and lower power consumption while maintaining pin-to-pin compatibility with certain legacy devices in the broader LC4000 family.

Complex Programmable Logic Devices Replacement Considerations

The LC4064V-75T44I is a verified faster-speed variant within the same package and logic density. Designers requiring higher throughput may substitute this part with the LC4064V-75T44I without hardware changes.
