LC4064C-5T44I

Complex Programmable Logic Devices Overview

The LC4064C-5T44I is a member of the ispMACH 4000C family, a high-performance Complex Programmable Logic Device (CPLD) manufactured by Lattice Semiconductor. This device integrates 64 macrocells and supports a maximum operating frequency (fMAX) of 400 MHz with a propagation delay (tPD) of 2.5 ns. It operates with a core voltage of 1.8 V for low dynamic power consumption while supporting 5 V tolerant I/O standards including LVCMOS 3.3, LVCMOS 2.5, LVCMOS 1.8, and LVTTL. The component is housed in a 44-pin TQFP package and is rated for industrial temperature ranges (-40°C to +105°C junction temperature).

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature grade (-40°C to +105°C Tj) as distinct from Commercial or Extended grades. Confirm the package type corresponds to the 44-pin Thin Quad Flat Package (TQFP). Ensure compatibility with JTAG In-System Programming (ISP) requirements for your design workflow.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the logic density requirements. The 5 ns speed grade (-5) offers a balance between performance and power. Consider the 44-pin TQFP package constraints regarding pin count and board space. Verify that the 1.8 V core voltage aligns with the system's power supply architecture.

Complex Programmable Logic Devices Part Context

The LC4064C belongs to the ispMACH 4000C series, which blends ispLSI 2000 and ispMACH 4A architectures. This family is designed for high performance and low power, offering excellent first-time-fit characteristics and timing predictability through global routing pools.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include LC4064V, LC4064B, or LC4064Z, depending on required voltage levels and temperature grades. Cross-family migration to ispMACH 4000V/Z may be considered for automotive applications requiring AEC-Q100 compliance.
