LC4064C-5TN100C

Complex Programmable Logic Devices Overview

The LC4064C-5TN100C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000C family, manufactured by Lattice Semiconductor. It features 64 macrocells organized into 4 Logic Array Blocks (LABs), providing high-density logic capabilities within a compact form factor. The device operates with a core voltage of 1.8V and supports 5V-tolerant I/O interfaces, including LVCMOS 3.3, LVCMOS 2.5, LVCMOS 1.8, LVTTTL, and PCI 3.3 standards. Key electrical parameters include a maximum operating frequency of 400 MHz, a propagation delay of 2.5 ns, and a typical standby current of 11.5 µA. It utilizes EEPROM technology for non-volatile configuration storage.

• Commercial temperature range support from 0°C to +90°C junction temperature.

Complex Programmable Logic Devices Applications

• Interface bridging between different voltage domains and protocol converters.
• State machine implementation and control logic in embedded systems.
• Address decoding and bus buffering in industrial control applications.
• General-purpose programmable logic for prototyping and low-volume production.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TN' against official Lattice documentation to confirm package details and temperature grade, as datasheets may list standard variants like 'TQFP-100'. Ensure RoHS compliance status is confirmed through the manufacturer's current product status notifications, as older series may have varying environmental declarations. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Complex Programmable Logic Devices Selection Notes

Select this component when a design requires moderate logic density (64 macrocells) with fast switching speeds and 5V tolerance on a 1.8V core. Compare against the LC4064V or LC4064Z variants if industrial (-40°C to +105°C) or automotive (-40°C to +130°C) temperature ranges are required, as the 'C' suffix typically denotes commercial grade. Consider pin count and I/O requirements relative to the TQFP-100 package limitations.

Complex Programmable Logic Devices Part Context

This device is part of the ispMACH 4000 family, which integrates features from previous ispLSI 2000 and ispMACH 4000A architectures. The family offers a balance of power efficiency and performance, utilizing a global routing scheme for predictable timing. The LC4064C represents the mid-range density option within the 4000 series, suitable for applications needing more logic than the LC4032 but less than the LC4128.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes within the same family include LC4064V-5TN100C (Industrial temp) and LC4064Z-5TN100C (Automotive temp). For legacy replacement, verify compatibility with ispMACH 4000A devices, though pinouts and electrical characteristics may differ. Check for Pin-to-Pin compatible upgrades from other CPLD families only if voltage levels and I/O drive strengths match.
