Device with an EEPROM having both a near field communication interface and a second interface
A peripheral device and a method for programming the read/writeable memory of the RFID circuitry by communications between either RF antenna or bus communications port controller interface or both. In the peripheral device, an EEPROM, bus communications controller interface, NFC interface, antenna, and logic controller operate to receive and transmit configuration and calibration data between a BLUETOOTH circuit and an external BLUETOOTH enabled device. The dual interfaced EEPROM is operable to share or partition its EEPROM between an NFC interface and a bus communications controller.
1. A peripheral device comprising:
a memory wherein the memory is dual interfaced such that a bus communications controller interface and a passive NFC interface can both be used by the memory to transmit data;
an NFC antenna, connected to said passive NFC interface, for communicating NFC signals with an external BLUETOOTH enabled device; and
a BLUETOOTH circuit in data communication with the bus communications controller interface
wherein the NFC interface is operable to be used for pairing the device with the external BLUETOOTH enabled device via a NFC link and to receive authentication information from the NFC interface, wherein the peripheral device is operable to store the authentication information in the memory, and
the peripheral device is operable to establish a BLUETOOTH connection to the external BLUETOOTH device using the authentication information without any manual entry of pairing data by a user.
2. The device of claim 1 , wherein the memory is an electronically erasable programmable read only memory (EEPROM).
3. The device of claim 1 , wherein the external BLUETOOTH enabled device is a mobile communication device.
4. The device of claim 1 further comprising a logic controller, wherein the logic controller is operable as an interface between the BLUETOOTH circuit and the memory to handle commands used to access the memory and to provide anti-collision control.
5. The device of claim 2 wherein the EEPROM may be subdivided into parts such that some parts may only be written to or read by the NFC interface.
6. The device of claim 1 further comprising an antenna connected to the BLUETOOTH circuit for communication with the external BLUETOOTH enabled device such that the peripheral device is adapted to be paired or configured through the antenna or through the NFC antenna.
7. A system comprising the peripheral device of claim 1 and the external BLUETOOTH enabled device, wherein the peripheral device and the external BLUETOOTH enabled device are operable to communicate with each other using BLUETOOTH and NFC.
8. The system of claim 7 where the peripheral device is selected from the group consisting of a personal digital assistant, a mobile phone, a laptop computer, a personal computer, a printer, a digital camera, an appliance and video game console.
9. A BLUETOOTH communication headset comprising:
a memory;
two interfaces wherein a first interface is a passive near field communication (NFC) interface and a second interface is a bus communications controller interface;
an NFC antenna, connected to said passive NFC interface, for communicating NFC signals with an external BLUETOOTH enabled device; and
a BLUETOOTH circuit in data communication with the bus communications controller interface
wherein the NFC interface is operable to be used for pairing the device with the external BLUETOOTH enabled device via a NFC link and to receive authentication information from the NFC interface, wherein the BLUETOOTH communication headset is operable to store the authentication information in the memory, and
the BLUETOOTH communication headset is operable to establish a BLUETOOTH connection to the external BLUETOOTH device using the authentication information without any manual entry of pairing data by a user.
10. A peripheral device comprising:
an electronically erasable programmable read only memory (EEPROM);
two interfaces wherein a first interface is a passive near field communication (NFC) interface and a second interface is a bus communications controller interface;
an NFC antenna, connected to said passive NFC interface, for communicating NFC signals with an external BLUETOOTH enabled device; and
a BLUETOOTH circuit in data communication with the bus communications controller interface;
a logic controller, wherein the logic controller is operable as an interface between the BLUETOOTH circuit and the EEPROM to handle commands used to access the EEPROM and to provide anti-collision control;
wherein the anti-collision control is based on an integrated circuit's individual serial number,
wherein the NFC interface is operable to be used for pairing the device with the external BLUETOOTH enabled device via a NFC link and to receive authentication information from the NFC interface, wherein the peripheral device is operable to store the authentication information in the memory, and
the peripheral device is operable to establish a BLUETOOTH connection to the external BLUETOOTH device using the authentication information without any manual entry of pairing data by a user.
