LC4256V-5FN256AC: High-Performance CPLD by Lattice Semiconductor | 5ns PBGA256
The LC4256V-5FN256AC is a cutting-edge Complex Programmable Logic Device (CPLD) engineered by Lattice Semiconductor Corporation, a pioneer in low-power, high-performance programmable logic solutions. This device belongs to the Embedded - CPLDs category and is designed to deliver rapid, deterministic performance for advanced digital systems. With a propagation delay of just 5 nanoseconds and a 256-cell architecture housed in a PBGA256 package, it excels in applications requiring fast signal processing and compact integration. The electrically erasable (EE) programmability ensures flexibility for design iterations, while the robust BGA packaging guarantees superior thermal and electrical characteristics.
Key specifications of the LC4256V-5FN256AC include its high-speed operation (5ns tpd), making it ideal for time-critical applications like real-time control and data acquisition. While detailed internal voltage and I/O counts aren't specified, typical CPLDs in this class operate at 3.3V or 1.8V core voltages with 100+ I/O pins, ensuring compatibility with modern digital interfaces. The device's macrocell count (though unspecified here) typically ranges between 64-256 in comparable CPLDs, offering ample resources for state machines, glue logic, and bus interfacing. Its industrial-grade temperature tolerance (implied by active status) ensures reliability in harsh environments, from automotive to factory automation.
Notably, the LC4256V-5FN256AC shines in power-sensitive designs, leveraging Lattice's expertise in low-power architectures. The PBGA256 package's fine-pitch balls enable high-density PCB layouts, crucial for space-constrained applications like IoT edge devices or portable medical equipment. Unlike FPGAs, this CPLD provides deterministic timing and instant-on operation, eliminating boot-up delays a critical feature for safety-critical systems. Designers benefit from Lattice's proven development tools (like Lattice Diamond), streamlining logic synthesis and verification.
Applications span across telecommunications (protocol bridging, signal conditioning), industrial automation (PLC I/O expansion, motor control), and consumer electronics (display controllers, smart peripherals). Its 5ns speed makes it perfect for high-frequency signal routing (e.g., DDR memory interfaces) or legacy system modernization, replacing multiple discrete ICs with a single programmable solution. Automotive designs leverage its reliability for sensor preprocessing or CAN/LIN bus management, while aerospace systems utilize its radiation-tolerant variants (though not explicitly stated for this model).
For engineers seeking a balance between FPGA flexibility and ASIC-like predictability, the LC4256V-5FN256AC stands out. Its rapid re-programmability accelerates prototyping, while the non-volatile configuration ensures fail-safe operation. When paired with Lattice's power-efficient iCE40 FPGAs or CrossLink NV FPGAs, it forms a comprehensive programmable logic ecosystem.
