The LC4384V-10TN176I from Lattice Semiconductor is a cutting-edge Complex Programmable Logic Device (CPLD) designed for high-performance embedded applications. This in-system programmable (ISP) IC combines 384 macrocells with 128 I/O pins, delivering exceptional logic density and connectivity in a compact 176-TQFP package. With a rapid 10ns propagation delay and 3.3V operation, it excels in time-critical systems requiring reliable programmability. The device operates across an industrial temperature range (-40 C to 105 C), making it suitable for harsh environments. Engineers favor this CPLD for its balance of speed, flexibility, and power efficiency in prototyping and production.
At its core, the LC4384V-10TN176I features 24 logic blocks with advanced routing architecture. The 3V to 3.6V internal voltage supply ensures compatibility with modern low-power designs while maintaining signal integrity. Its surface-mount 176-LQFP package (24x24mm) optimizes PCB space utilization. Key specifications include 5,000 usable gates, 64PT product terms per macrocell, and JTAG programming support. The device supports hot-socketing and features individual output enable controls, enhancing system reliability. These technical attributes make it a versatile solution for logic consolidation, interface bridging, and control applications.
The LC4384V-10TN176I shines in diverse applications including industrial automation, telecom infrastructure, and automotive systems. Its high I/O count enables complex bus interfaces like PCI or memory controllers, while the macrocell array efficiently implements state machines and glue logic.
