USBN9603/USBN9604 Universal Serial Bus
Full Speed Node Controller with Enhanced DMA Support
General Description
The USBN9603/4 are integrated, USB Node controllers.
Other than the reset mechanism for the clock generation cir-
cuit, these two devices are identical. All references to “the
device” in this document refer to both devices, unless other-
wise noted.
The device provides enhanced DMA support with many au-
tomatic data handling features. It is compatible with USB
specification versions 1.0 and 1.1, and is an advanced ver-
sion of the USBN9602.
The device 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 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 configu-
ration for different interrupt signaling requirements.
