LC4064V-5TN100C CPLD | Lattice Semiconductor | High-Speed Programmable Logic Device
The LC4064V-5TN100C is a cutting-edge Complex Programmable Logic Device (CPLD) developed by Lattice Semiconductor, designed to deliver exceptional performance in embedded systems and digital logic applications. This device stands out with its 5-nanosecond propagation delay, enabling real-time processing for time-sensitive operations. With 64 macrocells and 4 logic blocks, it offers a balanced architecture capable of implementing complex state machines, glue logic, and interface protocols. The 3V to 3.6V operating voltage ensures compatibility with modern low-power designs while maintaining robust signal integrity. Packaged in a compact 100-LQFP (14x14mm) format, it is ideal for space-constrained applications requiring high I/O density (64 pins). Its In-System Programmability (ISP) allows for field updates, reducing development cycles and enabling adaptive system configurations.
Engineers will appreciate the LC4064V-5TN100C's industrial-grade temperature range (0 C to 90 C TJ), making it suitable for harsh environments like factory automation or outdoor electronics. The device integrates Lattice's advanced E CMOS technology, ensuring low standby current and high reliability. Each macrocell supports both combinatorial and sequential logic, with programmable flip-flops for flexible timing control. The CPLD also features global and product-term clocking, allowing precise synchronization across multiple logic blocks. With its non-volatile configuration memory, the LC4064V-5TN100C retains its programming even during power cycles, eliminating the need for external boot devices. This feature is particularly valuable in mission-critical systems where instant-on operation is essential.
Target applications span across industrial control systems (PLC I/O expansion, motor control), telecommunications (protocol bridging, signal conditioning), and consumer electronics (display controllers, peripheral interfaces). In automotive systems, it can manage sensor arrays or dashboard logic, while in medical devices, it ensures reliable timing for diagnostic equipment. The CPLD's 5V-tolerant I/Os simplify interfacing with legacy components, and its hot-socketing capability prevents bus contention during live insertion. Designers can leverage Lattice's ispLEVER design tools for seamless development, including synthesis, place-and-route, and timing analysis. The toolchain supports industry-standard HDLs (VHDL, Verilog) and offers simulation models for verification.
For procurement flexibility, the LC4064V-5TN100C is available in commercial (0 C to 70 C) and industrial temperature variants, with lead-free and RoHS-compliant options. Its 10,000-program/erase cycle endurance guarantees long-term field serviceability. When compared to FPGAs, this CPLD provides deterministic timing and lower latency, making it preferable for control-plane applications. The device is also resistant to configuration upsets from radiation or noise, a critical factor in aerospace and defense systems. With over two decades of proven reliability in Lattice's 4000V family, this CPLD continues to be a go-to solution for legacy upgrades and new designs requiring fast, deterministic logic.
In summary, the LC4064V-5TN100C combines high speed, design flexibility, and ruggedness in a cost-effective package. Its blend of performance characteristics 5ns speed, 64 I/Os, and 3.3V operation positions it uniquely for bridging, glue logic, and control applications where FPGAs may be overkill. The extensive ecosystem of development tools and reference designs accelerates time-to-market, while the device's longevity ensures supply chain stability. Whether replacing discrete logic or enabling next-gen system features, this CPLD delivers a future-proof foundation for innovative digital designs across industries.
