4th Generation USB2.0 Flash Media Controller with Integrated Card Power FETs and HS Hub
Chapter 1 General Description
The USB2601/USB2602 is an Integrated “combo” High-Speed USB hub and Flash Media Controller.
The Flash media controller permanently resides on Port 1 of the Integrated USB hub.
1.1 High-Speed Hub
The integrated SMSC Hub is fully compliant with the USB2.0 Specification and will attach to a USB
host as a Full-Speed Hub or as a Full-/High-Speed Hub. The Hub supports Low-Speed, Full-Speed,
and High-Speed (if operating as a High-Speed Hub) downstream devices on all of the enabled
downstream ports.
A dedicated Transaction Translator (TT) is available for each downstream facing port. This architecture
ensures maximum USB throughput for each connected device when operating with mixed-speed
peripherals.
Datasheet
The Hub works with an external USB power distribution switch device to control V
downstream ports, and to limit current and sense over-current conditions.
All required resistors on the USB ports are integrated into the Hub. This includes all series termination
resistors on D+ and D– pins and all required pull-down and pull-up resistors on D+ and D– pins. The
over-current sense inputs for the downstream facing ports have internal pull-up resistors.
Throughout this document the upstream facing port of the hub will be referred to as the upstream port,
and the downstream facing ports will be called the downstream ports.
Three externally available ports are available for general USB device connectivity.
1.2 Flash Media Controller
The Bulk Only Mass Storage Class Peripheral Controller intended for supporting CompactFlash (CF
and CF Ultra I/II) in True IDE Mode only, SmartMedia (SM) and XD cards, Memory Stick (MS), Memory
Stick DUO (MSDUO) and Memory Stick Pro (MSPRO), Secure Digital (SD), and MultiMediaCard
(MMC) flash memory devices. It provides a single chip solution for the most popular flash memory
cards in the market.
The device consists of buffers, Fast 8051 microprocessor with expanded scratchpad, and program
SRAM, and CF, MS, SM and SD controllers. The SD controller supports both SD and MMC devices.
SM controller supports both SM and xD cards.
12K bytes of scratchpad SRAM and 768 Bytes of program SRAM are also provided.
Eleven GPIO pins are provided for indicators, external serial EEPROM for OEM ID and system
configuration information, and other special functions.
switching to
BUS
Internal power FETs are provided to directly supply power to the xD/SM, MMC/SD and MS/MSPro
cards.
The internal ROM program is capable of implementing any combination of single or multi-LUN
CF/SD/MMC/SM/MS reader functions with individual card power control and activity indication. SMSC
also provides licenses** for Win98 and Win2K drivers and setup utilities. Note: Please check with
SMSC for precise features and capabilities for the current ROM code release.

Chapter 6 Pin Descriptions
This section provides a detailed description of each signal. The signals are arranged in functional
groups according to their associated interface.
The “n” or “_N”symbol in the signal name indicates that the active, or asserted state occurs when the
signal is at a low voltage level. When “n” is not present before the signal name (or “_N” after the signal
name), the signal is asserted when at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signal. The term assert, or assertion indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation indicates that a signal is inactive.

pin, in order to set the transceiver’s internal bias
currents.
Analog TestATESTAIOThis signal is used for testing the analog section of the
chip and should be connected to VDDA33 for normal
operation.
Crystal
Input/External Clock
Input
XTAL1/
CLKIN
ICLKx24Mhz Crystal or external clock input.
This pin can be connected to one terminal of the crystal
or can be connected to an external 24Mhz clock when
a crystal is not used.
Note:The ‘SEL_CLKDRV and CLK_SEL[1:0]’ pins
will be sampled while RESET_N is asserted,
and the value will be latched upon RESET_N
negation. This will determine the clock source
and value.
Crystal OutputXTAL2OCLKx24Mhz Crystal
This is the other terminal of the crystal, or left open
when an external clock source is used to drive
XTAL1/CLKIN. It may not be used to drive any external
circuitry other than the crystal circuit.
Select Clock DriveSEL_CLKDRVI/O8PDSEL_CLKDRV. During RESET_N assertion, this pin will
select the operating clock mode (crystal or externally
driven clock source), and a weak pull-down resistor is
enabled. When RESET_N is negated, the value will be
internally latched and the internal pull-down will be
disabled.
Clock SelectCLK_SEL[1:0]I/O8PDSEL[1:0]. During RESET_N assertion, these pins will
select the operating frequency of the external clock, and
the corresponding weak pull-down resistors are
enabled. When RESET_N is negated, the value on
these pins will be internal latched and the internal pulldowns will be disabled.
