The USBN9602 is an integrated USB Node controller compatible
with the USB Specification Versions 1.0 and 1.1.
Integrated onto a single IC are the required USB transceiver
with a 3.3V Regulator, Media Access Controller,
USB endpoint (EP) FIFOs, a versatile 8-bit parallel interface,
MICROWIRE/PLUS? Interface and a clock generator.
A total of seven FIFO buffers support the different USB
messages: one bidirectional FIFO for the mandatory con-trol endpoint EP0 and six FIFOs for an additional six unidirectional
Endpoint Pipes to support USB interrupt, bulk and
isochronous data transfers. 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.
