ATF750C-10JI Application Field and Working Principle - Embedded - CPLDs (Complex Programmable Logic Devices)

CPLDs, or Complex Programmable Logic Devices, are integrated circuits that incorporate both programmable logic and memory which can be configured to perform specific user-defined functions. As an experienced leader in the embedded systems and technology industry, Atmel has been offering a broad portfolio of programmable logic solutions to meet the ever-increasing demands of the embedded industry. One of Atmel\'s latest offering is the Atmel ATF750C-10JI, an ultra-low power, low-cost CPLD device with integrated 8-bit instruction memory.

The ATF750C-10JI is a sensitive, commercial and industrial grade CPLD device that is ideal for applications requiring small form factor, low cost and requires minimum power consumption. It has a 1.2K to 10K logic elements for configuring, IO pins for signal and chip enable for recognition, user controllable pull-up and pull-down resistors, an on-board internal regulator, program memory, and up to 16 levels of hierarchy. With these features, the ATF750C-10JI is suitable for a wide range of embedded applications that calls for low-power, low-cost and creative possibilities.

Application Fields of ATF750C-10JI

The ATF750C-10JI can be used in a variety of embedded designs, such as consumer, industrial and automotive applications. Examples of consumer applications include mobile phones, digital cameras and consumer electronics. For industrial applications, the device can be used in robotics, energy and industrial control systems. In automotive applications, the device can be used in vehicle control modules, engine controllers, etc.

The utilization of the ATF750C-10JI also extends to keyless entry systems, garage door openers, consumer appliances, digital set-top boxes for utilizing buffered displays, and programming and controlling devices for home and industrial automation. Young engineers can also use the unique and minimalistic feature-set of the ATF750C-10JI to develop their own stand-alone applications for laboratory purposes.

ATF750C-10JI Working Principle

Atmel\'s ATF750C-10JI CPLD device follows an innovative design consisting of three main components: the Programmable Logic Array (PLA) core, the Instruction Memory (IM), and the Serial Interface Module (SIM). The PLA core is the most powerful component of any CPLD, as it contains the logic logic elements (LEs), IO cells, and register file, as well as the clocks, reset and control logic. Together, the logic elements and IO cells make the main body of the CPLD.

The instruction memory modules contain the user-defined instructions which are encoded and stored to control register states and other internal components. The SIM is responsible for serializing the data for communication with external devices, and for bit manipulation in registers. The instruction memory, serial interface and logic cells are also known as subsystems, and control how the device operates as a whole.

The Atmel ATF750C-10JI supports immediate configuration mode, which enables the device to respond quickly to any commands through a continuous reset cycle or power-up sequence. It also features a highly flexible architecture that provides greater flexibility compared to standard CPLDs. The device’s control signals, register states and other internal components can be programmed via the programming interface to configure the device for any given application.

For applications that require minimal power consumption, the ATF750C-10JI supports two low-power modes – low-power state and low-power idle mode. In low-power state, the device is placed in a state where all clocks are disabled and the logic elements, IO cells and register files are powered off. The low-power idle mode further reduces the power consumption by disabling all non-essential components and reducing the clock frequency.

Conclusion

Atmel\'s ATF750C-10JI CPLD device is an ideal choice for embedded devices that require low-power, low-cost and creative possibilities. The device takes advantage of an innovative three-component design that includes a Programmable Logic Array (PLA) core, an Instruction Memory (IM) and a Serial Interface Module (SIM). It provides configurable logic elements, IO cells and register files, as well as program memory and a range of user-controllable parameters. Thanks to its low-power modes, it is suitable for battery-powered devices, as well as those that operate in extreme temperature and voltage conditions. Overall, the ATF750C-10JI is an attractive choice for a variety of embedded applications.
