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 I²C^TM 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
