USB82640
Automotive USB 2.0 Hub and Flash Media Card
Controller Combo
Highlights
• AEC-Q100 compliance
- Microchip’s parts are tested to meet or
exceed the requirements of the AEC-Q100
automotive qualification standards
• PortMap
- Flexible port mapping and port disable
sequencing supports multiple platform
designs
• PortSwap
- Programmable USB differential-pair pin loca-
tions ease PCB design by aligning USB sig-
nal traces directly to connectors
• PHYBoost
- Programmable USB transceiver drive
strength for recovering signal integrity due to
compromised system environment
Target Applications
• Automotive integrated head unit
• Automotive breakout box
• Automotive media player dock
• Automotive consumer connectivity ports
• Portable device charging via USB
• Rear seat infotainment access
Key Benefits
• Single-chip compound device: USB 2.0 hub con-
troller with two hi-speed downstream ports and a
flash media controller
• Hub and flash media reader/writer configuration
from a single source:
- Configuration of internal code using an exter-
nal I2CTM EEPROM or SPI Flash
- Execution of external code from SPI Flash
- Support of custom vendor, product, and lan-
guage IDs when using an external EEPROM
• 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
• Integrated regulator for 1.8 V core operation
• External regulator mode for 1.8 V core operation
• RoHS compliant packages
- 48-pin (7x7 mm²) VQFN
• Temperature ranges:
- 48VQFN: -40 ºC to +85 ºC

USB82640
1.1 Device Features
1.1.1 HARDWARE FEATURES
• Single-chip hub and flash media controller
• USB82640 supports the temperature range of -40 °C to +85 °C
• Transaction Translator (TT) in the hub supports operation of FS and LS peripherals
• Full power management with individual or ganged power control of each downstream port
• Optional support for external firmware access via SPI interface
• Code execution via SPI ROM which must meet the following qualifications:
- 30 MHz or 60 MHz operation support
- Single bit or dual bit mode support
- Mode 0 or mode 3 SPI support
Compliance with the following flash media card specifications:
• Secure Digital 2.0/MultiMediaCard 4.2
- SD 2.0, SD-HS, SD-HC
- TransFlashTM and reduced form factor media
- 1/4/8 bit MMC 4.2
- Supports storage addressability of up to 2 TB

• Supports internal regulator for 1.8 V core operation
• Supports external regulator for 1.8 V core operation
1.1.2 CONFIGURABLE FEATURES
Default configuration is implemented in the USB82640 following a reset. The USB82640 may also be configured by an
external I2C EEPROM or external SPI ROM flash where the following features are supported.
• Customizable vendor ID, product ID, and device ID
• 12-hex digits maximum for the serial number string
• 29-character manufacturer ID and product strings for flash media reader/writer
• Compound device support on a port-by-port basis
- a port is permanently hardwired to a downstream USB peripheral device
• Select over-current sensing and port power control on an individual or ganged (all ports together) basis to match
the OEM’s choice of circuit board component selection
• Port power control and over-current detection/delay features
• Configure the delay time for filtering the over-current sense inputs
• Configure the delay time for turning on downstream port power
• Bus- or self-powered selection
• Hub port disable of non-removable configurations
• Flexible port mapping and disable sequencing supports multiple platform designs
• Programmable USB differential-pair pin location selection eases PCB layout by aligning USB signal lines directly
to connectors
• Programmable USB signal drive strength improves USB signal integrity using 4 levels of signal drive strength
• Indicate the maximum current that the 2-port hub consumes from the USB upstream port
• Manage the maximum current required for the hub controller
