LA4032V-75TN44E CPLD - High-Speed Programmable Logic Device by Lattice Semiconductor
The LA4032V-75TN44E from Lattice Semiconductor represents the cutting edge of Complex Programmable Logic Device (CPLD) technology. This high-performance IC combines 32 macrocells with an impressive 7.5ns propagation delay, making it ideal for time-critical applications in industrial automation, telecommunications, and automotive systems. The device operates on a 3.3V power supply (3V to 3.6V range) and features 30 I/O pins in a compact 44-pin TQFP package measuring just 10x10mm. With in-system programmability (ISP) and operation across an industrial temperature range (-40 C to +125 C), this CPLD offers unparalleled flexibility for demanding embedded control applications.
Engineers will appreciate the LA4032V-75TN44E's advanced architecture that provides both combinational and sequential logic capabilities. Each of the 32 macrocells can be independently configured, allowing for complex state machines and glue logic implementations. The device's 7.5ns maximum propagation delay ensures rapid response times, while the 3.3V operation makes it compatible with modern low-power systems. The surface-mount TQFP package enables high-density PCB designs while maintaining excellent thermal characteristics for reliable operation in harsh environments.
Key technical specifications include a 44-pin Thin Quad Flat Package (TQFP) with 30 usable I/O pins, supporting both 3.3V and 5V tolerant inputs. The CPLD features non-volatile E CMOS technology for reliable operation and features 600 usable gates. Programming is simplified through industry-standard tools, with the in-system programmability allowing for field updates without physical removal from the circuit board. These features make the LA4032V-75TN44E particularly valuable for applications requiring post-deployment firmware updates or configuration changes.
The LA4032V-75TN44E excels in numerous applications including industrial control systems (PLC interfaces, motor control), automotive electronics (sensor interfaces, lighting control), telecommunications equipment (protocol conversion, signal conditioning), and consumer electronics (appliance control, display interfaces). Its robust design features include hot-socketing capability (live insertion/removal protection) and superior noise immunity, making it reliable in electrically noisy environments. The device is also compliant with industrial EMC standards, ensuring stable operation in challenging electromagnetic conditions.
Lattice Semiconductor's reputation for quality shines through in the LA4032V-75TN44E's design and manufacturing. As an active product in Lattice's portfolio, it benefits from ongoing technical support and guaranteed long-term availability.
