

Supports suspend and resume power management functions.



Supports remote wakeup feature.



Supports Battery Charging specification revision 1.2.

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 the MAC protocol refers to IEEE standard

802.3-2000.

4.9.1 Features:



10/100Mbps 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 a nibble at a time, with 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 2kB RX memory.



Two LED indicators used by Ethernet multi-function.

4.10 CAN Bus Controller

The FT905 series contains two controllers, CAN bus 0 and CAN bus 1. 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 uses 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. FT905 CAN bus supports 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 Mbit/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.



Supports single shot transmission.



Supports an abort transmission feature.



Readable error counters and last error code capture supported.
