USBN9603 Universal Serial Bus Full Speed Function Controller with Enhanced DMA Support
PRELIMINARY

USBN9603 Universal Serial Bus
Full Speed Function Controller with Enhanced DMA Support
General Description
The USBN9603 is an integrated, USB Node controller that
features enhanced DMA support with many automatic data
handling features. It is compatible with USB specification ver-
sions 1.0 and 1.1, and is an advanced version of the currently
available USBN9602.
A single IC integrates the required USB transceiver with a
3.3V regulator, a Serial Interface Engine (SIE), USB end-
point (EP) FIFOs, a versatile 8-bit parallel interface, a clock
generator and a MICROWIRE/PLUS鈩?interface. Seven
endpoint pipes are supported: one for the mandatory con-
trol endpoint and six to support interrupt, bulk and isochro-
nous endpoints. Each endpoint pipe has a dedicated FIFO,
8 bytes for the control endpoint and 64 bytes for the other
endpoints. The 8-bit parallel interface supports multiplexed
and non-multiplexed style CPU address/data buses. A pro-
grammable interrupt output scheme allows device con鏗乬u-
ration for different interrupt signaling requirements.
