The TJA1048T is a high speed differential bus controller that is designed to drive and receive data on a differential bus system. It is a single-channel transceiver designed to support the CAN ISO 11898-2 protocol in automotive applications. It is suitable for use in high speed data transactions such as proprietary protocols and network protocols.

The main features of the device are as follows:

• Integrated 8-bit A/D converter with on-chip temperature sensor
• Wide input and output voltage ranges
• Flexible power supply design for efficient power management
• Compatibility with three-state logic
• Optimized for signal transmission speeds up to 1 Mbps.

The TJA1048T operates using a three-state logic, which allows it to provide simultaneous access to inputs and outputs on a differential bus system. The three-state logic utilizes two inputs, A and B, and two outputs, C and D, that are connected to the data lines. When a logic 1 signal is sent to A or B, either one of the outputs (C or D) will be asserted, while the other output will remain inactive. Alternatively, if logic 0 is sent to the inputs, both outputs will be deasserted.

The TJA1048T is designed to support the ISO 11898-2 standard. This standard defines the communication protocol used by nodes on a differential-bus system. The protocol defines the method of communication between two nodes, which includes both the data transmission rate and the message format. The protocol defines the start and stop conditions for data frames, how data is encoded and decoded, how errors are detected and corrected, and how the bus is managed.

In terms of hardware, the TJA1048T provides three configurable I/Os for easy connection to external peripherals. These I/Os are used for data transfer to and from the processor, as well as for error signal management. The device also has an integrated 8-bit A/D converter with an on-chip temperature sensor, which allows the user to monitor and control the operating temperature of the device. Finally, the device has an integrated charge pump circuit which allows the user to supply power to either 2.5V or 3.3V.

The TJA1048T is a flexible and reliable single-channel transceiver designed to provide high speed and reliable communication in automotive applications. It is compatible with the ISO 11898-2 protocol, and its on-chip features enable the user to easily integrate it into any system. The device is also well-suited for harsh environments due to its wide input and output voltage ranges, and its flexible power supply design.
