Lattice Semiconductor ISPLSI2064A-80LT100: A High-Density Programmable Logic Device for Demanding Embedded Systems
In the realm of embedded systems design, where performance, power efficiency, and physical space are often at a premium, the choice of logic device is critical. The Lattice Semiconductor ISPLSI2064A-80LT100 stands out as a robust, high-density programmable logic solution engineered to meet these stringent demands. As a member of the mature but highly capable ispLSI 2000A family, this device combines a rich architecture with in-system programmability, offering designers a flexible and reliable foundation for complex digital logic implementation.
At the core of the ISPLSI2064A-80LT100 is a high-density architecture featuring 64 macrocells. These macrocells are organized into four Generic Logic Blocks (GLBs), interconnected by a Global Routing Pool (GRP). This internal structure provides a predictable and fast signal path, which is crucial for maintaining timing integrity in high-performance applications. The device is rated for an impressive 80 MHz maximum operating frequency (fmax), ensuring it can handle the processing speeds required by modern embedded control, communication, and data processing tasks.
A key advantage of this device is its In-System Programmability (ISP). Utilizing a simple 5-wire IEEE 1149.1 (JTAG) interface, designers can reprogram the logic of the device after it has been soldered onto a printed circuit board (PCB). This capability dramatically simplifies the development cycle, allows for rapid design iterations, and enables field upgrades, which significantly reduces time-to-market and overall product life cycle costs.
The "LT100" suffix denotes a 100-pin Thin Quad Flat Pack (TQFP) package. This low-profile surface-mount package is ideal for space-constrained applications, making it a perfect fit for portable and compact embedded systems where board real estate is limited. Furthermore, the device operates on a 3.3V supply voltage, striking an excellent balance between power consumption and speed. This lower voltage operation translates to reduced overall system power consumption, a vital parameter for battery-operated and thermally sensitive equipment.
Typical applications for the ISPLSI2064A-80LT100 are extensive. It is perfectly suited to function as a glue logic consolidator, replacing numerous fixed-function standard logic ICs to reduce component count and increase reliability. It is also widely used in complex state machine control, bus interfacing (e.g., PCI local bus control), and high-speed data routing and management within telecommunications hardware, networking equipment, and sophisticated industrial control systems.
ICGOODFIND: The Lattice Semiconductor ISPLSI2064A-80LT100 remains a compelling choice for engineers designing demanding embedded systems. Its blend of high logic density, proven 80MHz performance, and invaluable in-system programmability, all delivered in a space-efficient, low-power package, provides a timeless solution for integrating and managing complex digital functions reliably and efficiently.
