MC33390D

The MC33390D is an integrated, low cost, transceiver solution for automotive applications. It is an Inter-Integrated Circuit (I2C) transceiver, providing an optimized interface between on board microcontrollers and outboard devices such as sensors, motors, and other devices. The MC33390D offers a combination of low power consumption, high speed, and high noise immunity for enhanced system performance.

The MC33390D is ideal for communication interface in automotive control systems, such as those requiring in-vehicle high speed serial data transmission. The high speed and low power consumption, along with its inherent error checking, make it an ideal solution for automotive control systems. The MC33390D features a multi-Piconet support, allowing simultaneous communication of up to eight nodes and allowing for network size expansion. The multi-Piconet support also makes it suitable for other applications where high speed, low power consumption, and flexible data transfer are required.

The working principle of the MC33390D is based on the bi-directional, cyclic communication of digital signals. The data is transmitted in the form of serial bytes, which are then encoded, decoded, and stored using an on-chip RAM and Flash memory. The data transmission is initiated by the master node, which sends out digital data packets to the peripheral nodes, which acknowledge the transaction and send back their own responses.

The MC33390D is also equipped with Serial Peripheral Interface (SPI) and Universal Asynchronous Receiver Transmitter (UART). The SPI and UART features provide the necessary flexibility for the communication interface in various applications. The MC33390D supports a wide range of bus speeds, allowing for efficient data transfer for up to a maximum rate of 500 kBps.

The MC33390D also offers integrated ESD protection for its I2C, UART, and SPI channels. The integrated on-chip protection ensures reliable communication of digital signals from various sources, such as external transceivers, sensors, and motors. The integrated ESD protection also ensures enhanced system reliability, by protecting against sudden electrical disturbances or power surges.

The MC33390D is an ideal choice for cost-sensitive and power-sensitive projects requiring efficient data transfer. It is also ideal for automotive control systems and communication interface in a wide range of applications. The MC33390D provides an optimized interface between on board microcontroller and out board devices, offering low power consumption, high speed, and high noise immunity for enhanced system performance.
