LC4384B-5FN256I CPLD | 384-Cell, 5ns Delay | Lattice Semiconductor

The LC4384B-5FN256I from Lattice Semiconductor is a high-performance Complex Programmable Logic Device (CPLD) designed for applications demanding rapid logic execution and compact integration. With 384 macrocells and a blazing-fast 5ns propagation delay, this CPLD excels in real-time processing, making it a top choice for communication protocols, industrial automation, and consumer electronics. Its PBGA256 package ensures efficient thermal management and space-saving PCB layouts, while Lattice's robust ecosystem simplifies development with intuitive design tools and comprehensive documentation.

Engineers favor the LC4384B-5FN256I for its scalable logic density and low-latency performance. Each macrocell supports both combinational and sequential logic, enabling flexible implementation of state machines, counters, and data path controls. The device operates reliably across industrial temperature ranges, backed by Lattice's reputation for quality. Key specifications include a 3.3V core voltage (typical for CPLDs) and support for high-speed I/O standards like LVCMOS and LVTTL, ensuring compatibility with modern digital systems.

Applications span diverse sectors: In 5G infrastructure, the CPLD handles signal routing and error correction; in automotive systems, it manages sensor fusion and CAN bus interfaces. Medical devices leverage its deterministic timing for ultrasound beamforming, while IoT gateways use it to consolidate glue logic. The LC4384B-5FN256I outperforms competing FPGAs in power efficiency for fixed-logic tasks, drawing <50mA active current. Its non-volatile configuration memory eliminates external boot ROMs, streamlining board design.

Lattice provides the ispLEVER Classic design suite for programming the CPLD via JTAG or SPI. Hardware features include 256-ball grid array (BGA) pins with programmable slew rates and drive strength. Security options prevent IP theft through bitstream encryption. For prototyping, the MachXO3L Development Kit offers pin-compatible evaluation. Compared to older LC4000-series CPLDs, the 4384B variant delivers 30% better performance-per-watt and 20% smaller footprint.

With lead-free RoHS compliance and a 10-year longevity commitment, the LC4384B-5FN256I future-proofs embedded designs. Global stock is available at authorized distributors like Digi-Key and Mouser, with volume pricing under $15/unit.
