STULPI01B Product
Page
STULPI01 is a stand-alone solution able to add a high
speed USB connection in Application-Specific-
Integrated-Circuits and System-on-Chips where fast
data exchange rate, complexity and low power
consumption are a main concern.
The STULPI01 is a high speed (480 Mbps) USB 2.0
transceiver which is compliant with ULPI (UTMI+ Low
Pin Interface) and OTG (On-The-Go) specifications,
providing a complete physical layer solution for any
high speed USB host, device or OTG dual role core.
STULPI01 is optimized for low power consumption,
and minimal die/package dimensions.

OTG Functionality: The Intelligent Solution |
|
STULPI01 is compliant with OTG specifications
providing point-to-point communication, supporting
dual role features between portable devices such as
mobile handsets, PDAs, digital still cameras, digital
video cameras and MP3 players. This means
information from a PC could be downloaded onto OTG
equipment such as a PDA and then the PDA could be
taken on the road and serve as the host to support
printing or music downloading to another device.

DDR Or SDR Mode Supported |
|
Unlike full- and low-speed USB systems which utilize
serial interfaces, the high-speed STULPI01 solution
requires a parallel interface between the controller
and the PHY in order to run the bus at 480 Mbps.
This leads to a corresponding increase in complexity
and pin count. ULPI keeps this down to only 8 or 12
signals because it combines just three control signals,
plus clock, with a 4 or 8-bit bi-directional data bus.
The 4 and 8-bit modes are known as double (DDR)
and single data rate (SDR) respectively.
ULPI Standard Minimizes Pin Count |
ULPI stands for UTMI+ low pin interface and is
designed specifically to reduce the pin count of
discrete high-speed USB PHYs. Pin count reductions
minimize the cost and footprint of the PHY chip on
the PCB and reduce the number of pins dedicated
to USBs for the link controller. As a result of these
capabilities, ULPI is quickly becoming the new
interface standard among system and chip designers.
 Supports 480 Mbit/s high-speed, 12 Mbit/s full-speed
and 1.5 Mbit/s low-speed modes of operation.
On request, 26 MHz or 19.2 MHz oscillator
frequency with external crystal, can be provided
Supports 2.7 V UART mode
Ability to control external charge pump for higher
VBUS currents
Single supply, +3 V to +4.5 V voltage range
Integrated dual voltage regulator to supply internal
circuits with stable 3.3 V and 1.2 V.
Integrated over current detector
Integrated HS termination and FS/LS/OTG pull-up/
pull-down resistors
Power down mode with very low power consumption
for battery-powered devices
