General Description
The USBN9603/4 are integrated, USB Node controllers.
The only difference between the USBN9603 and USBN9604 devices is the effect of a hardware reset on the
clock generation circuit. In the USBN9604, assertion of the RESET input causes the clock generation circuit to
be reset, the same as during Power-on reset, whereas in the USBN9603 the clock generation circuit is not reset.
This difference is particularly important for bus-powered operations. In such applications, the voltage
provided by the bus may fall below acceptable levels for the clock generation circuit. When this occurs, a
reset must be applied to this circuit to guarantee proper operation. This low voltage detection is typically
accomplished in bus-powered applications using a voltage sensor such as the LP3470 to appropriately reset the
CPU and other components including the USBN9604.
Other than the reset mechanism for the clock generation circuit, these
two devices are identical. All references to "the device"
in this document refer to both devices, unless otherwise noted.
The device provides enhanced DMA support with many automatic data
handling features. It is compatible with USB specification
versions 1.0 and 1.1, and is an advanced version 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/PLUSÖ interface. Seven endpoint
pipes are supported: one for the mandatory control endpoint
and six to support interrupt, bulk and isochronous 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 programmable interrupt
output scheme allows device configuration for
different interrupt signaling requirements.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
