I don't have any idea of what "can" can be, related to chips. Any help?

Programa que transmite dati¡os a numerosos destinatarios: "Controller Area Network "
Explanation:
Programa que transmite datos a múltiples destinatarios a la vez.
multicast

1. In communications networks, to transmit a message to multiple recipients at the same time. Multicast is a one-to-many transmission similar to broadcasting, except that multicasting means sending to specific groups, whereas broadcasting implies sending to everybody. When sending large volumes of data, multicast saves considerable bandwidth, because the bulk of the data is transmitted once from its source through major backbones and are multiplied, or distributed out, at switching points closer to the end users. In a unicast system, the data is replicated entirely to each recipient. See IP multicast, IGMP and SRM.

2. In digital television broadcasting, to send multiple channels of programming over the allotted bandwidth for digital transmission rather than one high-definition TV (HDTV) signal.

Controller Area Network (CAN) is a multicast shared serial bus standard, originally developed in the 1980s by Robert Bosch GmbH, for connecting electronic control units (ECUs). CAN was specifically designed to be robust in noisy environments and can utilize a differential balanced line like RS-485. It can be even more robust against noise if twisted pair wire is used. Although initially created for automotive purposes (as a vehicle bus), nowadays it is used in many embedded control applications (e.g., industrial) that may be subject to noise.

Bit rates up to 1 Mbit/s are possible at networks length below 40 m. Decreasing the bit rate allows longer network distances (e.g. 250 kbit/s at 250 m).

The CAN data link layer protocol is standardized in ISO 11898-1 (2003). This standard describes mainly the data link layer — composed of the logical link control (LLC) sublayer and the Media Access Control (MAC) sublayer — and some aspects of the physical layer of the ISO/OSI Reference Model. All the other protocol layers are left to the network designer\'s choice.

Data transmission

CAN transmits data through a binary model of \"dominant\" bits and \"recessive\" bits where dominant is a logical 0 and recessive is a logical 1. If one node transmits a dominant bit and another node transmits a recessive bit then the dominant bit \"wins\" (a logical AND between the two).
Commonly when used with a differential bus, a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) scheme is implemented: if two or more devices start transmitting at the same time, there is a priority based arbitration scheme to decide which one will be granted permission to continue transmitting. Specifically, a dominant bit is asserted by creating a voltage across the wires while a recessive bit is simply not asserted on the bus.

During arbitration, each transmitting node monitors the bus state and compares the received bit with the transmitted bit. If a dominant bit is received when a recessive bit is transmitted then the node stops transmitting (i.e., it lost arbitration). Arbitration is performed during the transmition of the identifier field.

Frames

All frames (aka messages) begin with a start-of-frame (SOF) bit that, obviously, denotes the start of the frame transmission.

CAN has four frame types:

* Data frame: a frame containing node data for transmission
* Remote frame: a frame requesting the transmission of a specific identifier
* Error frame: a frame transmitted by any node detecting an error
* Overload frame: a frame to inject a delay between data and/or remote frames

Data frame

The data frame is the only frame for actual data transmission. There are two message formats:

* Standard: with 11 identifier bits
* Extended: with 29 identifier bits

The CAN standard requires the implementation must accept the standard format and may accept the extended format.
