INTER-CHIP USB IP

 

Inter-Chip USB is a low power, chip to chip variant of the USB standard interface. InterChip USB is a USB-IF and a ETSI (European telecommunications Standards Institute) standard. Typical use case of  InterChip USB is to provide a high troughput link to a UICC (SIM or USIM card).

INVIA has pioneered Inter-Chip USB since its inception and has developed innovative, patent protected, silicon proven Inter-Chip USB IP solutions  :

• Inter-Chip USB PHY IP: connects to a standard USB digital controller with UTMI or ULPI interface.

• Inter-Chip USB Bridge IP

                - USB 2.0 host downstream port to Inter-Chip USB peripheral

                -  Inter-Chip USB downstream port to USB 2.0 peripheral.

• Inter-Chip USB voltage class converter IP (1.55V to 3.6V)

• USB Clock recovery IP: implements USB  without external oscillator.

 

Highlights

• Fully compliant with ETSI TS 102 600
• Very low footprint : 3 mm² typical 0.35µm implementation
• 4kV ESD protection
• "All-in-one" pin-programmable mode select (PHY, Bridge, Voltage class converter)

 

Power Consumption

• 100 µA typical Vbus current
• Slew rate control to minimize radiated EMI

Deliverables

• Specification and Integration Manual
• GDSII and Layer Map files
• Library Exchange Format (LEF) defining size and pin locations
• RTL Behavioral Model
• Timing Constraint Files
• Netlist in SPICE format for LVS

 

    Prototyping Board

INVIA's Inter-Chip USB Development board is based on a test chip that incorporates all the IPs listed above. The board includes a USB Type A connector, a USB Type B connector, a SIM connector and a flex with eight pin SIM.

 

Inter-Chip USB IP has a strong track record of silicon implementation with volume production in 0.35 µm. Test chips and characterization reports of these test chips can be shared under NDA. Please contact sales@invia.fr for more information.
