GAL22V10D-10LJN

The GAL22V10D-10LJN (Generic Array Logic) is an embedded-CPLD (Complex Programmable Logic Device) created by Lattice Semiconductor. It is used in digital circuit designs and is a low cost, low power, and simple way to create custom logic gates from complex functions. The GAL22V10D-10LJN features 16 macrocells, each of which has multiple logic gates in it - allowing for a variety of different configurations. The GAL22V10D-10LJN also features an internal oscillator for the clock, which eliminates the need for an external oscillator. This helps reduce overall system cost, as an external oscillator requires more power and space.

The GAL22V10D-10LJN is used to create custom digital designs, such as digital signal processing applications and memory interfaces. It has also been used in industrial control applications, such as stepper motor control and automated assembly lines. Because the device is highly configurable, it can be used to implement very specific logic designs which may have not been possible with other devices. Additionally, the low cost and low power requirements make it a cost-effective option for low-volume production applications.

The working principle of the GAL22V10D-10LJN is fairly simple. Each macrocell in the device can contain up to six logic gates, and each gate can have up to three inputs and two outputs. The logic gates within the macrocell are configured by the user according to their desired logic design, either through soldering or through software. The clock input determines when the logic from each macrocell is evaluated and outputs are generated. The inputs and outputs can be connected to external devices, such as LED drivers or stepper motor controllers. By connecting the GAL22V10D-10LJN to such devices, custom logic designs can be created with ease.

In summary, the GAL22V10D-10LJN is a low cost, low power, and simple way to create custom logic gates from complex functions. It is an embedded-CPLD device manufactured by Lattice Semiconductor, and is used in industrial control applications, digital signal processing systems, and memory interfaces. The GAL22V10D-10LJN features up to 16 macrocells which can be configured by the user to create custom logic designs. Additionally, the device features an internal clock oscillator which eliminates the need for an external oscillator. The inputs and outputs of the device can be connected to external devices, allowing for complete integration into a variety of systems.
