Introduction

The DS89C387TM is a powerful, user-friendly device that allows fast and easy implementation of application-specific interface designs. This device can be used for interfacing with up to 32 devices such as microprocessors and peripherals. It also offers support for many popular bus protocols such as I2C, SPI, SMbus, 1-Wire, etc. The integrated 3-phase, full-duplex auto-parallel bus allows it to be connected to devices that use different bus protocols simultaneously. The device can be used to provide a universal, fully-integrated, high-performance interface solution for a wide variety of applications, including embedded systems, industrial automation, medical, automotive, aviation, and telecommunications.

Application field

The DS89C387TM can be used in a variety of industrial, automotive and consumer applications, such as factory automation, control systems, instrumentation, and medical equipment. It is especially useful for applications that require reliable and efficient communication between various devices. It can be used as a communications controller to connect a range of microprocessors, sensors, and/or peripherals to one or more LAN networks.

The device also provides a rapid prototyping services for new applications during their development stages. It offers a simple programming environment, along with a wide range of configurable interface options. This facilitates the development of custom control algorithms and drivers that are tailored to specific application requirements.

In addition, the device can be used to develop peripheral interface designs that are optimized for specific applications. This allows the device to be used to simplify the development of sophisticated and efficient peripherals, such as wireless modems and wireless sensors.

Working Principle

The DS89C387TM uses three functional layers of hardware, software, and protocol layers to establish control communication. The hardware layer consists of configurable I/O pins, signal processing logic and analog interface circuitry. The software layer consists of a variety of controller firmware programs, which are stored in on-chip non-volatile memory. The protocol layer includes support for various communication protocols such as I2C, SPI, SMbus, and 1-Wire. This allows the device to be used to develop an interface between different device types.

The device supports the connection of up to 32 devices. Each device can utilize up to eight I/O lines, four interrupt lines, and one bi-directional bus line. The interrupts are used to detect the presence of connected devices and to identify them. The bus line is used for synchronization between devices.

The device can be configured for serial or parallel operation. Serial communication is used for devices that support clock synchronous protocols such as I2C and SPI. Parallel communication is used for devices that use stop-start protocol or other analog communication protocols. In addition to this, the device can also support bidirectional communication.

The DS89C387TM can also be used to develop custom interface designs using the integrated analog circuitry. The integrated analog circuitry supports many popular data conversion functions, such as comparator, attenuator, reference, and gain factor. This allows the device to convert analog signals into digital signals and vice versa. The device also supports various analog filters, such as lowpass, highpass, and band-pass filters.

Conclusion

In summary, the DS89C387TM is a highly flexible, user-friendly device that is ideal for applications requiring fast and easy implementation of custom interface designs. It supports a wide array of protocols, including I2C, SPI, SMbus, 1-Wire and more. The device also includes powerful, integrated analog circuitry and can be used to develop custom interfaces for a variety of applications. With its integrated 3-phase, full-duplex auto-parallel bus, it can be connected to devices using different bus protocols simultaneously.
