SPEAR-09-B042
Main blocks
8.5
Ethernet controller
The Ethernet MAC controller provides the following features:
●
Compliant with the IEEE 802.3-2002 standard
●
MII interface to the external PHY
●
Supports 10/100 Mbps data transfer rates
●
Local FIFO available (4 Kbyte RX, 2 Kbyte TX)
●
Supports both half-duplex and full-duplex operation. In half-duplex operation,
CSMA/CD protocol is provided for, as well as packet bursting and frame extension at
100 Mbps
●
Programmable frame length to support both standard and jumbo ethernet frames with
size up to 16 Kbyte
●
A variety of flexible addresses filtering modes are supported
●
A set of control and status registers (CSRs) to control GMAC core operation
●
Native DMA with single-channel transmit and receive engines, providing 32/64/128-bit
data transfers
●
DMA implements dual-buffer (ring) or linked-list (chained) descriptor chaining
●
An AHB slave acting as programming interface to access all CSRs, for both DMA and
GMAC core subsystems
●
An AHB master for data transfer to system memory
●
32-bit AHB master bus width, supporting 32, 64, and 128-bit wide data transactions
8.6
USB2 host controller
SPEAr BASIC has two fully independent USB 2.0 hosts and each one is constituted with 5
major blocks:
●
EHCI capable of managing high-speed transfers (HS mode, 480 Mbps)
●
OHCI that manages the full and the low speed transfers (12 and 1.5 Mbps)
●
Local 2-Kbyte FIFO
●
Local DMA
●
Integrated USB2 transceiver (PHY)
Both hosts can manage an external power switch, providing a control line to enable or
disable the power, and an input line to sense any over-current condition detected by the
external switch.
One host controller at time can perform high speed transfer.
