LC4064V-75TN44I CPLD - High-Performance 3.3V 64-Macrocell Programmable Logic Device
The LC4064V-75TN44I represents Lattice Semiconductor's advanced 3.3V Complex Programmable Logic Device (CPLD) solution, delivering exceptional performance for modern digital designs. With 64 macrocells organized across 4 logic blocks, this device offers 7.5ns maximum propagation delay at 3.0-3.6V operation, making it ideal for timing-critical applications. The 44-pin TQFP package (10 10mm) provides 30 user I/Os with robust -40 C to +105 C industrial temperature range support. Its in-system programmability (ISP) through IEEE 1149.1 JTAG interface enables field upgrades without physical device removal, significantly reducing development cycles and maintenance costs.
Engineers will appreciate the LC4064V-75TN44I's architectural advantages, including zero-power E CMOS technology that eliminates standby current consumption. The device features 36 inputs and 30 outputs with programmable slew rate control, offering 5V tolerant I/Os for mixed-voltage system designs. With 800 usable gates and 64 macrocells featuring individual clock/reset controls, it provides flexible implementation of complex state machines and glue logic. The 7.5ns pin-to-pin delay ensures reliable operation in high-speed interfaces, while the 100MHz maximum frequency supports demanding processing requirements.
From a technical perspective, the LC4064V-75TN44I demonstrates superior signal integrity with its advanced I/O buffer design. The device supports multiple I/O standards including LVCMOS 3.3V/2.5V/1.8V and LVTTL, accommodating diverse system requirements. Security features include 128-bit AES encryption for bitstream protection and dual boot capability for fail-safe operation. Designers benefit from Lattice's ispLEVER design software with VHDL/Verilog support, along with comprehensive reference designs and IP cores to accelerate development.
This CPLD finds extensive applications across multiple industries including industrial automation (PLC I/O interfaces, motor control), telecommunications (protocol bridging, line cards), medical devices (patient monitoring systems), and consumer electronics (display controllers, smart home devices). Its combination of high reliability (10,000 program/erase cycles minimum) and low power consumption (typically 50 A standby current) makes it particularly suitable for battery-powered equipment. The device also serves excellently in legacy system upgrades, replacing multiple discrete logic ICs with a single programmable solution.
For procurement and technical support, the LC4064V-75TN44I is available through authorized distributors with full traceability. Lattice provides complete documentation including datasheets, application notes, and hardware design guidelines. The device is RoHS compliant and has undergone rigorous qualification testing, ensuring long-term availability for industrial and commercial applications. Designers can leverage Lattice's technical support ecosystem including reference designs, evaluation boards, and online communities to streamline their development process with this versatile CPLD solution.
