ISPLSI2064-100LJ CPLD - High-Performance In-System Programmable Logic Device | Lattice Semiconductor
The ISPLSI2064-100LJ from Lattice Semiconductor is a cutting-edge Complex Programmable Logic Device (CPLD) designed for high-performance embedded applications. With its in-system programmability (ISP), this device allows engineers to reconfigure logic functions on-the-fly without removing the chip from the circuit board. Featuring 64 macrocells and 2000 equivalent gates, it delivers robust logic density for implementing complex state machines, glue logic, and interface bridging. The device operates at a speedy 10ns propagation delay with a 4.75V to 5.25V power supply range, making it suitable for both industrial and commercial applications where reliability and speed are critical.
This CPLD comes in a compact 84-PLCC (29.31x29.31mm) package with 64 I/O pins, offering excellent connectivity for interfacing with processors, memory, and peripheral devices. Its 16 logic blocks are interconnected via a high-speed global routing pool, ensuring efficient signal distribution. The 0 C to 70 C operating temperature range makes it versatile for various environments. Engineers appreciate its 5V tolerance on I/O pins, simplifying integration with legacy systems while maintaining compatibility with modern 3.3V components through careful design.
The ISPLSI2064-100LJ excels in applications requiring real-time processing and flexible logic implementation. Its architecture supports wide input gating (up to 36 product terms per macrocell) and buried registers for efficient state machine design. Security features include programmable security bit protection to prevent unauthorized access to configuration data. The device is fully compliant with IEEE 1149.1 JTAG boundary scan standards, enabling robust system testing and debugging capabilities. Lattice's proven ispLEVER design software provides comprehensive support for schematic entry, HDL synthesis, and simulation.
Typical applications include industrial control systems (PLC interfaces, motor control), telecommunications (protocol conversion, line cards), automotive electronics (sensor interfacing, dashboard logic), and consumer electronics (display controllers, input processing). Its ability to consolidate multiple discrete logic components into a single programmable device reduces board space, lowers power consumption, and improves system reliability. The 100-pin PLCC package offers excellent thermal characteristics for sustained operation in demanding conditions.
As an active product in Lattice's mature CPLD family, the ISPLSI2064-100LJ benefits from stable long-term supply and extensive technical documentation. Designers can leverage numerous reference designs and application notes to accelerate development. For applications requiring higher density, Lattice offers upward-compatible devices in the same family with additional macrocells and I/O. The combination of predictable timing, non-volatile configuration, and instant-on operation makes this CPLD particularly valuable in systems requiring reliable startup without external configuration memory.
