SP490EN-L/TR is an interface-level IC designed for nodal architectures. It is suited for UARTs and provides a wide range of features, from low-baud rate communication to high-speed data communication. This article will explore the applications and working principles of the SP490EN-L/TR.

Applications

The SP490EN-L/TR is a versatile device, with a wide range of applications. It is commonly used in systems that need reliable high-speed data communication between nodes or devices. It can be used to send and receive data on a UART, with very low latency. It is also used in many networking, system-level, and embedded applications, as it supports quick, low-cost system level integration.

The SP490EN-L/TR can also be used for serial switched communication. It achieves very low transmission and reception latency, without the need for extra hardware or software. This makes it ideal for applications that require real-time communication, such as automotive networks. In addition, theSP490EN-L/TR is suitable for low power and noise-sensitive applications, as it supports programmable power and noise control features.

The SP490EN-L/TR also supports a wide range of data rates. It can support communication at baud rates up to 12 megabits per second (Mbps). This makes the SP490EN-L/TR an excellent choice for high-speed applications such as industrial automation, robotics, or high-speed serial networking.

Working Principle

The working principle of the SP490EN-L/TR involves the use of two sets of signaling pins. A control pin and a receive/transmit pin. The control pin is used to send control signals to the SP490EN-L/TR and also to receive data from it. The receive/transmit pin is used to receive data (or transmit data, depending on the configuration).

When the control pin is asserted, the SP490EN-L/TR responds by activating its loops and performing either a receive or a transmit function. When data is received, the SP490EN-L/TR stores it in a buffer and then triggers an interrupt when the data has been received. The interrupt informs the system that data is ready to be read from the SP490EN-L/TR\'s buffer. The SP490EN-L/TR then enters a wait state until it is ready to receive more data.

When transmitting data, the SP490EN-L/TR first checks if the receive/transmit pin is already active. If so, it will activate the transmit loop, which prepares the data to be sent. Then, when the control pin is asserted, the SP490EN-L/TR will begin transmitting the data on the transmit pin. Again, an interrupt will be triggered when the data has been sent, so that the SP490EN-L/TR can enter a wait state until it is ready to send more data.

The SP490EN-L/TR provides several other features to improve performance, reduce noise and power consumption, and more. It provides programmable transmit and receive thresholds and power control features, as well as advanced features such as noise filtering, data framing, and data integrity checking. All of these features combined make the SP490EN-L/TR an ideal choice for a wide range of interface-level applications.

Conclusion

The SP490EN-L/TR is a versatile interface-level IC designed for UARTs and high speed data communication. It supports high data rates up to 12 Mbps and features programmable transmit and receive thresholds, power control, noise filtering, data framing, and data integrity checking. The SP490EN-L/TR can be used in many applications, from industrial automation systems, to automotive networks and low-power applications.
