The GAL20V8B-25QJN is a complex programmable logic device (CPLD) from Lattice that belongs to their family of GAL devices. A CPLD generally refers to a programmable integrated circuit (IC) that contains multiple logic elements, registers, and/or memory/configuration cells. It is often regarded as being relatively low in cost, yet still providing high density, reliability, and reprogrammability. GAL20V8B-25QJN is a 20-pin device that comes in a standard PLCC package. It offers eight I/O pins and eight internal registers. The device offers both active high and active low output, allowing it to be used in a wide variety of applications.

The GAL20V8B-25QJN has a number of features that make it a suitable choice for many applications. Firstly, it is easy to program with Lattice’s standard GAL Products programmer. Secondly, it has a low standby current requirement, making it suitable for battery-powered applications. Finally, the device has a power-down feature, allowing it to be shut down to save power when not in use. This makes it ideal for applications where power is at a premium.

The GAL20V8B-25QJN is commonly used in applications such as industrial process control, factory automation, security, and automotive systems. The device can also be used to create custom logic functions, such as frequency dividers, logic gates, and counters. Additionally, the GAL20V8B-25QJN can be used to implement arithmetic and bitwise algorithms, such as arithmetic circuits and digital filters. As a result, it is a popular choice for applications that require complex logic.

The GAL20V8B-25QJN uses field programmable array (FPGA) technology to store and update configuration data. This means that the device can be reprogrammed on the fly, allowing for quick changes to be made to its logic functions or configuration settings. A GAL20V8B-25QJN is typically programmed one register at a time, and the data is loaded into the device blind, meaning that the programmed device only knows its configuration when the data enters it. This allows for a high level of flexibility, allowing the designer to make changes and updates to the logic configuration quickly and easily.

In summary, the GAL20V8B-25QJN is a cost-effective and reliable complex programmable logic device. It offers eight I/O pins and eight internal registers, as well as a low standby current requirement and power-down feature. This makes it suitable for a wide range of applications, including industrial process control, factory automation, security, and automotive systems. Additionally, the device is easy to program, and can be updated or reprogrammed on the fly with FPGA technology. As a result, the GAL20V8B-25QJN is a reliable, versatile, and cost-effective choice for many different embedded applications.
