Embedded technology has come a long way and it has many applications in today’s world. From aerospace and military applications to commercial and consumer products, embedded systems enable computers to perform complex tasks with the help of programmable logic devices. Amongst these devices, complex programmable logic devices, or CPLDs, are widely used. The ATF750CL-15SC is one such CPLD and it has numerous applications within the embedded domain.

ATF750CL-15SC Application Field

The ATF750CL-15SC is an advanced CMOS-based, Programmable Logic Device (PLD), designed to provide low-cost, high-density, and logic integration. The device is suitable for various control, addressing, and interface applications. It offers a large programmable logic array, high-speed clock management capabilities, and flexible Flash-based programming, making it suitable for a wide range of embedded applications, including personal computers, in-vehicle infotainment systems, industrial automation systems, as well as medical and industrial control systems.

The device is built on the common 0.6-micron CMOS architecture and incorporates 31 user-programmable macrocells and 293Kbits of High-Density Programmable Logic Array (HSPLA). This makes it suitable for dynamic and static application-specific configurations. Additionally, the device features JTAG boundary-scan and IEEE 1149.1 standard-wide interconnect protocol support, which facilitates production testing of large fields of interconnected devices.

Furthermore, the device offers a highly efficient and flexible memory-based programming mechanism, where a byte-wide Flash ROM holds configuration data and supports in-device and full VHDL designs. This ensures that the device can be programmed at various stages of the system\'s deployment life cycle, right from the beginning of the design process to the final manufacturing stage.

ATF750CL-15SC Working Principle

The ATF750CL-15SC is programmed to perform specific tasks through an extensive range of user-programmable features. It has two distinct application-oriented architectures, with the first one being for Logical Elements (LEs) and the second one for Logic Control and Interconnection (LCIs). The LEs provide for the programmable logic operations, while the LCIs control the logic operations and provide for on-chip bus systems.

The programmable logic operations are conveyed from the user-defined bit pattern in the instruction words. These patterns are then decoded to the LEs, and the outputs are combined to perform the specified functions. Additionally, these instruction words provide direct access to all available resources, including the LEs, LCIs, and the external device periphery.

Interconnection between LEs and LCIs is also supported. This provides for the system\'s control logic operations, and complex timing control, interaction of the application-specific logic and device control logic, and the sharing of resources between LEs and LCIs. Furthermore, interconnection can also be used to control the device\'s input and output clock lines, which can be synchronized externally.

Overall, the ATF750CL-15SC is a high-density CPLD with excellent performance, which makes it suitable for a wide range of embedded applications. Its user-programmable features make it easy to program and update, and its on-chip bus systems provide enhanced support for system level architectures.
