ON Semiconductor G65SC22PEI-2 Versatile Interface Adapter (VIA)

The ON Semiconductor G65SC22PEI-2 is a highly integrated Versatile Interface Adapter (VIA) designed to provide flexible interface solutions for microprocessor-based systems. This powerful interface chip is a direct descendant of the well-known 6522 VIA and is widely used in a variety of applications ranging from industrial control systems to consumer electronics.

Featuring a 40-pin dual in-line package (DIP), the G65SC22PEI-2 is equipped with a wealth of features that make it an ideal choice for interfacing with peripheral devices. It includes two independent 8-bit bidirectional I/O ports, which allow for easy connection to external devices. Each port is supported by its own data direction register, giving the user complete control over data flow and enabling the device to accommodate a wide range of peripherals.

In addition to the I/O ports, the G65SC22PEI-2 boasts two 16-bit timer/counters that can be utilized for event counting or interval timing. These timers are highly configurable and can operate in different modes, providing versatility in timing tasks. The VIA also contains a shift register that can be used for serial-to-parallel and parallel-to-serial data conversion, further enhancing its utility in communication applications.

One of the key features of the G65SC22PEI-2 is its ability to handle interrupt signals through its programmable interrupt control logic. This allows for efficient and responsive system design by enabling the device to prioritize and manage multiple interrupt sources. The VIA's handshake lines also ensure smooth data transfer with handshake-driven peripherals, ensuring data integrity and synchronization.

The G65SC22PEI-2 operates over a wide range of voltages and provides TTL compatibility, making it suitable for interfacing with both standard and low-power devices. Its robust design and proven reliability make it a trusted component for engineers and designers looking to build sophisticated control systems. With its combination of flexibility, performance, and ease of use, the ON Semiconductor G65SC22PEI-2 remains a preferred choice for those seeking a versatile interface solution.
