PCI7421ZHK is a type of interface-controller product manufactured by Advantech. It is an embedded 16-bit PCI bus controller, supporting 32-bit data transfers. It integrates a PCI-bus, an I/O card, and a Field-Programmable Gate Array (FPGA) into one unit, allowing users to configure the functionality of their system to meet their specific needs.

The PCI7421ZHK is designed to provide a reliable, high-performance data transfer controller. It features dual-channel data transfers, a bus master mode, and a packet structure which allows for easy transfer of multiple packets. The device is compliant with the PCI specification and has a wide voltage range, so it can be used in various applications. It also comes with a power management system and a watchdog timer to ensure that the system remains running in the case of system failure or power loss.

The PCI7421ZHK is a versatile controller and can be used in various application areas, such as industrial automation, medical and entertainment systems, automotive systems and test and measurement equipment. The device is suitable for applications requiring high performance, reliable operation, and low latency. Its packet-oriented transaction methodology provides efficient data transfer and error handling, making it ideal for applications requiring high throughput and low latency.

The PCI7421ZHK\'s working principle is based on a dual-channel transaction model. In this model, two channels are used for transferring data between two devices. One of the channels is for transmitting data and the other for receiving. The PCI7421ZHK supports DMA (direct memory access) transfer, which allows for data transfer without CPU intervention, reducing system overhead and increasing data transfer speeds. The PCIe configuration provided by the device allows for data transfer speeds of up to 8Gbps.

The PCI7421ZHK also has advanced features, such as integrated busmaster support, packet pacing, and error detection and correction. It incorporates a Field-Programmable Gate Array (FPGA) to enable users to customize their system and enhance its performance. Additionally, it also supports various programming languages and provides a robust API, allowing users to easily develop control software.

In summary, the PCI7421ZHK is a versatile, multi-function interface-controller which can be used to provide reliable and high-performance data transfer. It has a wide range of applications and supports advanced features such as DMA transfer, packet pacing, and error detection and correction. It also reduces system overhead with its efficient data transfer and error handling mechanisms, making it an ideal choice for applications requiring high throughput and low latency.
