The MCP2515T-E/SO is an interface controller module designed to connect and input data from different CAN (Controller Area Network) buses. The product is composed of a central controller, a transmitting unit, a reception unit, two transceivers, and a 128-byte FIFO (First In, First Out) RAM. Other features include a low-power mode, two interrupts and a programmable bit timing to support different CAN protocols. The module supports 8 x 8 bytes and 11 x 8 bytes extended formatted data frames.

The application fields of the MCP2515T-E/SO include automotive, industrial, medical, military, and avionics applications. Specifically, it can be used in electronic control units (ECUs), car data loggers, smart home devices and automation systems, as well as in automotive, military, avionics and medical devices. This module is designed to comply with the ISO 11898-2 standard and is suitable for operating temperatures from -40°C to 85°C.

The MCP2515T-E/SO operates using a unified single-chip controller, which both transmits and receives data. The single-chip controller uses the CAN bus to interface with the microcontroller (MCU) or the host processor. It is responsible for the arbitration, arbitration slots, data byte stretching, error detection, RX Buffer management, and the like. The transmitting unit is used to provide the MCU or the host processor with an interface to the CAN bus. It can transmit data in accordance with the protocols. It also contains a FIFO RAM that stores up to 128 bytes of data. The reception unit is used to receive CAN bus data frames and provides them to the MCU or the host processor. It also contains a RAM for storing received data.

The two transceivers use differential signal lines for transmission and reception. They act as interface units between the MCU and the CAN bus. The transceivers use logic-level signals for communication, and are compatible with both standard and extended format data frames. The transceivers are also responsible for error detection, bus arbitration, and generation of error frames when necessary.

The MCP2515T-E/SO also features a low-power mode, which allows the module to enter a low-power state. It uses a programmable bit timing in order to reduce power consumption while enabling support for different CAN protocols. The module also contains two interrupt lines that can be used to act as a general-purpose interrupt. In addition, the module can be configured to support different communication modes, such as polling and sending data frames, or bus-monitoring mode.

In summary, the MCP2515T-E/SO is an interface controller module intended to interface with a microcontroller or host processor to a CAN bus. It is composed of a central controller, a transmitting unit, a reception unit, two transceivers, and a 128-byte FIFO RAM. The module is suitable for automotive, industrial, medical, military, and avionics applications. It complies with the ISO 11898-2 standard and is suitable for operating temperatures from -40°C to 85°C.
