The BU8874 is an interface chip designed for use in a host microcontroller and is used for low-speed and low-cost serial communication applications. It is ideal for applications such as home automation, industrial control systems, medical device communication, and time domain multiplexing (TDM).

The BU8874 is designed to work in a 3-wire asynchronous serial data format, with the ability to carry both 8-bit and 10-bit data words. It is capable of operating in both master and slave, transmitting or receiving data as required, and supports both full-duplex and half-duplex communications. Data speeds of up to 10 Kbps can be achieved, although speeds up to 20 Kbps can be achieved with with additional hardware support. The clock signal used by the BU8874 is independent of the data rate, and can be up to 10 times higher than the data rate.

The BU8874 has a wide range of features, including programmable baud rate settings, break detection, data error detection and correction, communication settings on a per-channel basis, and adjustable transmit and receive impedance settings. It is designed to help achieve consistent data rates and provide improved communication reliability and reliability of data packages.

The BU8874 has an integrated voltage regulator, allowing it to be used in a wide range of applications. It is compatible with a range of standard microcontrollers, including Intel, PIC and ARM, and can be used in both single and multi-channel systems. The BU8874 also supports an Automatic Baud Rate Recognition (ABRD) feature, which allows the chip to automatically detect the correct serial communication settings for the environment it is operating in.

The BU8874 has several operating modes, which can be configured through the host microcontroller. These include master/slave mode, deep-sleep mode, and extended mode. Master/slave mode allows the BU8874 to act as a command master and/or data slave in a multi-channel system. Deep-sleep mode is used to reduce power consumption when the system is idle. Extended mode can be used to increase the data rate over the standard 10 Kbps maximum.

The BU8874 has an integrated voltage regulator and can be powered directly from the microcontroller. It is designed to operate over a wide range of operating temperature ranges, and is rated for operation up to 85°C. The BU8874 also offers protection against both ESD and EMI.

The BU8874 offers numerous features, making it ideal for applications requiring low-cost, low-speed serial communication. It is capable of operating in both master and slave modes, with support for extended data rates up to 20 Kbps, and features a wide range of protection mechanisms. The integrated voltage regulator ensures reliable operation over a wide range of temperatures, and allows it to be easily integrated into any host system. The BU8874 is an ideal choice for applications that require efficient, low-cost serial communications.
