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™ 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.
Outstanding Features
q Low EMI, low standby current, 24 MHz oscillator
q Advanced DMA mechanism
q Fully static HALT mode with asynchronous wake-up
for bus powered operation
q 5V or 3.3V operation
q Improved input range 3.3V signal voltage regulator
q All unidirectional FIFOs are 64 bytes
q Power-up reset and startup delay counter simplify sys-
tem design
q Simple programming model controlled by external controller
q Available in two packages
USBN9603SLB: small footprint for new designs and
portable applications
USBN9603-28M: standard package, pin-to-pin com-
patible with USBN9602-28M
