Complex Programmable Logic Devices (CPLDs) are widely used in various embedded systems. The GAL16V8D-20QPI is a highly integrated product with a 16-macrocell architecture and up to 20 product terms per macrocell. It is also pin-compatible with the widely used 16V8 devices, making it ideal for use in existing designs. This device is suitable for applications that require high speed, complex logic functions, reliability and low cost.

The GAL16V8D-20QPI operates in two power supply voltages, 3.3 volts (Vcc1), and 5 volts (Vcc2), allowing two different power supply configurations, both with typical active power dissipation of 300mW max. The CPLD allows the user to configure up to 16 interconnectable AND gates, with up to 128K bits of programmable logic. The GAL16V8D-20QPI also features low propagation delay, low standby current and low operating temperature.

The main application fields of the GAL16V8D-20QPI is industrial automation, automotive, consumer electronics, multimedia, networking, and now industrial Internet of Things (IIoT). The chip is used for a variety of industrial control tasks and can also be used for high-reliability embedded applications in consumer products. The device can also be used to control various subsystems in automotive applications and for relays, sensors, and other components.

The GAL16V8D-20QPI is programmable through a serial programming interface such as the I2C, JTAG, or SPI protocols. It is configured by the user, either through an integrated development environment (IDE) or a vendor-provided programming interface. The device can also be configured using external memory devices, such as PROMs, EPROMs, or EEPROMs. Once programmed, the device can be mounted onto a printed circuit board (PCB) and connected to other components.

The working principle of the GAL16V8D-20QPI is based on the classical logic gates. An input to the logic gate is either a 0 or a 1. OR, AND, NAND and NOR gates are basic building blocks of CPLDs. OR and AND gate combinations can implement a variety of logic functions, whereas the NAND and NOR gates can also be used for implementing complex functions. Depending on the user’s preference and requirements, different combinations of modules can be assembled together to make a CPLD configure.

The GAL16V8D-20QPI offers a variety of features, such as high-speed operation, low-power consumption, reliability, low cost, and low power dissipation. Due to its modular structure and its flexibility, it is a powerful solution for many embedded systems.
