LA4064V-75TN44E CPLD - High-Speed 3.3V Programmable Logic Device | Lattice Semiconductor
The LA4064V-75TN44E represents Lattice Semiconductor's advanced solution for complex digital logic implementations requiring both high speed and design flexibility. This in-system programmable CPLD features 64 macrocells organized in an optimized architecture that delivers 7.5ns maximum propagation delay while operating at 3.3V core voltage. The device's 30 I/O pins support versatile interfacing capabilities, and its industrial-grade temperature range (-40 C to +125 C) ensures reliable operation in harsh environments. Engineers will appreciate the 44-TQFP package's balance of compact footprint (10 10mm) with sufficient pin count for moderate complexity designs.
With its 7.5ns pin-to-pin delay performance, the LA4064V-75TN44E stands out among 3.3V CPLDs for timing-critical applications. The device utilizes Lattice's proven ispLSI technology, offering non-volatile configuration storage and 10,000 program/erase cycle endurance. Power consumption is optimized through advanced CMOS process technology, typically drawing <50mA active current at maximum frequency. The architecture supports flexible pin locking and incremental design changes without complete recompilation, significantly reducing development time for iterative projects.
The LA4064V-75TN44E finds particular advantage in industrial control systems where its combination of deterministic timing and reprogrammability addresses evolving standards. Its 30 I/O pins can implement various interface standards including LVCMOS 3.3V/2.5V with programmable slew rate control. The macrocell architecture features individual clock/reset control and buried register feedback paths for efficient state machine implementation. Security features include read/write protection and a unique ID code to prevent unauthorized access to the configuration.
This CPLD excels in applications requiring glue logic consolidation, protocol bridging, or real-time control functions. Typical implementations include motor control interfaces, sensor data conditioning, and system power management. The automotive-grade temperature qualification makes it suitable for under-hood electronics, while the instant-on capability benefits power-critical applications. Designers migrating from older 5V CPLDs will appreciate the seamless transition with 5V-tolerant I/Os (when properly configured) and improved power efficiency.
Lattice provides comprehensive development support through the Diamond Programmer software and third-party synthesis tools. Reference designs demonstrate best practices for clock distribution, power decoupling, and signal integrity in the 44-TQFP package. The LA4064V-75TN44E's combination of performance, density, and industrial reliability positions it as an optimal choice for designers needing programmable logic between simple PALs and larger FPGAs.
