USB82642

Automotive USB 2.0 Hub and Flash Media Card

Controller Combo

Highlights

Key Benefits

• AEC-Q100 compliance

• Single-chip USB 2.0 hub controller with 2

exposed hi-speed downstream ports

- Microchip’s parts are tested to meet or

exceed the requirements of the AEC-Q100

automotive qualification standards

• The dedicated flash media reader is internally

attached to a 3rd downstream port of the hub as a

USB compound device

• PortMap

• Hub and flash media reader/writer configuration

from a single source:

- Flexible port mapping and port disable

sequencing supports multiple platform

designs

- Configures internal code using an external

SPI ROM

• PortSwap

- Supports execution of external code from SPI

Flash EEPROM

- Programmable USB differential-pair pin loca-

tions ease PCB design by aligning USB sig-

nal traces directly to connectors

- Supports custom vendor, product, and lan-

guage ID when using an external EEPROM

• PHYBoost

• Supports full power management with individual

or ganged power control of each downstream port

- Programmable USB transceiver drive

strength recovers signal integrity

• Transaction Translator (TT) in the hub supports

operation of FS and LS peripherals

Target Applications

• Single 24 MHz crystal support

• Control of peripheral I²C devices by USB host

• Automotive integrated head unit

• Automotive breakout box

• Supports internally or externally regulated 1.8 V

core voltage operation

• Automotive media player dock

• Automotive consumer connectivity ports

• Portable device charging via USB

• Supports storage addressability of up to 2 TB

• One GPO output

• RoHS compliant packages

- 48-pin (7x7 mm²) VQFN

• Temperature ranges:

- 48VQFN: -40 ºC to +85 ºC
