USB2642
USB 2.0 Hub and Flash Media Card Controller Combo
General Description
The USB2642 is a USB 2.0 compliant, hi-speed hub
and card reader combo solution. This fully-integrated,
single chip solution provides USB expansion and flash
media reader/writer integration. The Microchip
USB2642 provides an ultra fast interface between a
USB host and today’s popular flash media formats. The
controller allows read/write capability to flash media
including the following:
• Secure DigitalTM (SD)
• SD High CapacityTM (SDHC)
• SD Extended CapacityTM (SDXC)
• MultiMediaCardTM(MMC)
• Embedded MultiMediaCardTM (eMMC)
The USB2642 offers a versatile, cost-effective and
energy-efficient hub controller with 2 downstream USB
2.0 ports and a flash media interface. The flash media
interface can support sustained transfer rates exceed-
ing 35 MB/s.
Additionally, the USB2642 provides an I2CTM over USB
bridge and an SD over USB bridge. The I2C bridge
allows for control of any I2C slave device operating at
50KHz serial clock.
Highlights
PortMap
- Flexible port mapping and port disable
sequencing supports multiple platform
designs
PortSwap
- Programmable USB differential-pair pin loca-
tions eases PCB design by aligning USB sig-
nal traces directly to connectors
PHYBoost
- Programmable USB transceiver drive
strength recovers signal integrity
Features
• Single-chip USB 2.0 hub controller with 2
exposed hi-speed downstream ports
• The dedicated flash media reader is internally
attached to a 3rd downstream port of the hub as a
USB compound device
• Hub and flash media reader/writer configuration
from a single source:
- Configures internal code using an external
SPI ROM
- Supports execution of external code from SPI
Flash EEPROM
- Supports custom vendor, product, and lan-
guage ID when using an external EEPROM
• Supports full power management with individual
or ganged power control of each downstream port
• Transaction Translator (TT) in the hub supports
operation of FS and LS peripherals
• Single 24 MHz crystal support
• Control of peripheral I2C devices by USB host.
• Supports internally or externally regulated 1.8 V
core voltage operation
• Supports storage addressability of up to 2TB
• RoHS compliant package
- USB2642: 48-pin (7x7 mm²) QFN
• Temperature ranges:
- Commercial Range (0 ºC to +70 ºC)
- Industrial Range (-40 ºC to +85 ºC)
Target Applications
• Desktop and mobile PCs
• Monitors and televisions
• Mobile PC docking
• Consumer A/V
• Media players/viewers
• Printers
• Flash media card readers/writers

It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at docerrors@microchip.com. We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for cur-
rent devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the
revision of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you are
using.
