4.9

Ethernet Controller

The Ethernet controller contains an on-chip 10/100BASE-TX Ethernet transceiver and Media Access

Control (MAC) designed to provide high performance of frame transmission and reception. The Ethernet

transceiver is compliant with 10/100BASE-TX Ethernet standards, such as IEEE802.3/802.3u and ANSI

X3.263-1995, and MAC protocol refers to an IEEE standard 802.3-2000.

4.9.1 Features



10/100 Mbps data transfer.



Conforms to IEEE 802.3-2002 specification.



Supports full-duplex and half-duplex modes.

Supports CSMA/CD protocol for half-duplex operation.

Supports IEEE802.3x flow control for full-duplex operation.



Programmable MAC address.



CRC-32 algorithm calculates the FCS nibble at a time, automatic FCS generation and checking,

able to capture frames with CRC errors if required.



Promiscuous mode support.



Station Management (STA) entity included.



Supports double buffering for 2kB TX and 4kB RX memory.



Two LED indicators used by Ethernet multi-function.

CAN Bus Controller

The FT900/1/2/3 series contains two CAN controllers, CAN0 and CAN1. Controller Area Network (CAN) is

a high performance communication protocol for serial data communication. It is widely used in

automotive and industrial applications. However this is expanding due to its reliability and feasibility. CAN

bus use a multi-master bus scheme with one logic bus line and equal nodes. The number of nodes is not

limited by the protocol. Nodes do not have specific addresses. Instead, message identifiers are used,

indicating the message content and priority of the message. FT900 CAN bus controllers support

multicasting and broadcasting with an external CAN transceiver.

4.10.1

Features



Conforms to protocol version 2.0 parts A and B.



Supports bit rates of up to 1 Mb/s.



Supports standard (11-bit identifier) and extended (29-bit identifier) frames.



Support hardware message filtering with dual/single filters.



64 Bytes receiver and 16 Bytes transmitter FIFO.



No overload frames are generated.



Supports normal and listen-only modes.
