USBN9602 is an integrated USB Node controller compatible with the USB Specification Versions 1.0 and 1.1, released by National Semiconductor Corporation in 1998. The controller integrates a USB transceiver, a 3.3V regulator, a 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 control 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 programmer can program endpoint FIFOs via the 8-bit parallel interface.
