USB Interface
34
The eCOG1X includes a USB 2.0 compatible peripheral module. It operates in USB host and
peripheral modes, with support for On-The-Go functions. It supports low speed (1.5Mb/s), full speed
(12Mb/s), and high speed (480Mb/s) modes.
An internal PHY supports low speed and full speed modes. High speed mode is supported with an
external PHY, using a ULPI bus connection.
The USB core in the eCOG1X offers the following features:
•
•
•
•
The USB core requires 4Kbytes of working memory, used for the endpoint data buffers. This is taken
from the top of the internal memory and cannot then be accessed directly by the processor. Reading
and writing to this memory is always done either through the USB core FIFO registers or with the DMA
peripheral and the slave FIFO.
The USB core is controlled through a set of memory mapped registers, located at an address defined
by the MMU. The USB DMA channel is controlled through the eCOG1X internal peripheral registers.
Low speed (LS), Full Speed (FS) and High Speed (HS) operation
USB host, peripheral and On-The-Go (OTG) use
Internal PHY for LS, FS and OTG operation.
ULPI interface for use with external HS PHY.
