The CS82C37AZ is a programmable interrupt controller designed to manage interrupts in microprocessor-based systems. It operates by receiving interrupt requests from various sources and prioritizing them based on the programmed priority levels. The controller then generates interrupt acknowledge signals to the requesting devices, allowing them to proceed with their respective interrupt service routines. The CS82C37AZ also supports cascading, enabling multiple controllers to be connected together to handle a larger number of interrupts.
The CS82C37AZ is commonly used in various applications where efficient interrupt handling is required. Some typical application fields include: - Personal Computers (PCs) - Embedded Systems - Industrial Automation - Communication Systems - Medical Equipment - Gaming Consoles
These alternative models offer similar functionality to the CS82C37AZ and can be considered as replacements depending on specific requirements and availability.
