USBN9603/USBN9604 Universal Serial Bus

Full Speed Node Controller with Enhanced DMA Support

General Description

Outstanding Features

●

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.

Low EMI, low standby current, 24 MHz oscillator

●

Advanced DMA mechanism

●

Fully static HALT mode with asynchronous wake-up

for bus powered operation

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.

●

5V or 3.3V operation

●

Improved input range 3.3V signal voltage regulator

●

All unidirectional FIFOs are 64 bytes

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.

●

Power-up reset and startup delay counter simplify sys-

tem design

●

Simple programming model controlled by external controller

●

Available in two packages

— USBN9603/4SLB: small footprint for new designs

and portable applications

— USBN9603/4-28M: standard package, pin-to-pin

compatible with USBN9602-28M
