Block description
The STULPI01 integrates a comparator for the VBUS, ID line detector, differential HS data
driver, differential and single-ended receivers, low dropout voltage regulators, and control
logic.
The STULPI01 provides a complete solution for connection of a digital USB
host/device/OTG controller to a USB bus.
Oscillator and PLL
An external clock (digital square wave
STULPI01A or STULPI01B).
The PLL internally produces all frequencies needed for operation:

Voltage reference
This block provides the precise reference voltage needed by internal circuit.
It requires a 12 kΩ +/- 1% resistor connected to the R
Power-on-reset (POR)
The power-on-reset circuit generates a reset pulse upon power-up which is used to initialize
the entire digital logic. Power-on-reset senses the V
During the power-on-reset pulse, the ULPI pins are in a high impedance state with pull-
down/pull-up resistors disabled.
UTMI + CORE
This is the digital heart of the chip and performs the bit-stuffing, NRZI decoding and serial-
to-parallel conversion during receive and the reverse operation during transmit for HS and
FS/LS.
ULPI wrapper
This implements the ULPI related protocol and conversion from UTMI+ to ULPI interface.
This block also implements the interrupt logic and complete ULPI register set.
60 MHz clock for the UTMI core and ULPI interface controller
1.5 MHz for low-speed USB data
12 MHz for full-speed USB data
480 MHz for high-speed USB data
