LC4064V-25T48C

Complex Programmable Logic Devices Overview

The LC4064V-25T48C is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4000V family, manufactured by Lattice Semiconductor Corporation. This device features 64 macrocells and supports up to 30 I/O pins. It operates within a supply voltage range of 3.0 V to 3.6 V and offers a maximum propagation delay of 2.5 ns with a maximum operating frequency of 400 MHz. The component is designed for surface-mount installation in a 48-pin TQFP package, suitable for commercial temperature ranges.

Complex Programmable Logic Devices Feature Summary

• High-performance logic with a maximum propagation delay of 2.5 ns and fMAX of 400 MHz.
• Supports In-System Programming (ISP) via JTAG interface for flexible design updates.
• Integrated global clock pins with programmable polarity control for precise timing management.
• Operates on a single 3.3 V power supply, simplifying power distribution requirements.

Complex Programmable Logic Devices Applications

• General-purpose digital logic replacement for legacy TTL/CMOS circuits.
• Interface bridging between different voltage domains or protocol converters.
• State machine implementation in industrial control systems.
• Address decoding and bus arbitration in embedded computing architectures.

Complex Programmable Logic Devices Procurement Notes

Verify the specific pin count and package type against the datasheet, as the model suffix 'T48' indicates a 48-pin TQFP, which differs from the common 44-pin variant. Confirm that the 3.3 V supply requirement aligns with the target system's power rails. Ensure the design toolchain supports the ispMACH 4000V family for programming and verification.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density of logic (64 macrocells) is required with fast switching speeds. Compare against the LC4064V-25T44C if board space allows for a smaller 44-pin package, noting the difference in available I/O pins. Consider the ispMACH 4000B or Z families if lower power consumption or additional security features are prioritized over the specific performance characteristics of the V series.

Complex Programmable Logic Devices Part Context

The LC4064V-25T48C is part of the ispMACH 4000V family, which represents an evolution of Lattice's high-density CPLD technology. This family is characterized by its SuperFAST architecture, enabling high-speed operation while maintaining compatibility with standard 3.3 V systems. It serves as a robust solution for designs requiring non-volatile configuration and reprogrammability without the complexity of FPGA flows.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other variants within the LC4064V series with different package options, such as the LC4064V-25TQ100C for higher I/O counts. Cross-family replacements like the MachXO2 series offer similar functionality but utilize SRAM-based FPGA technology, requiring external configuration memory and differing power profiles.
