Device with an EEPROM Having Both a Near Field Communication Interface and a Second Interface

摘要

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 wireless personal area network circuit and an external wireless personal area network enabled device. The dual interfaced EEPROM is operable to share or partition its EEPROM between an NFC interface and a bus communications controller.

主权项

1. A lock/security peripheral device comprising:
a passive near field communication (NFC) interface; a data interface; a memory, wherein the memory is dual interfaced such that the passive NFC interface and the data interface can both be used by the memory to transmit data; an NFC antenna, connected to the passive NFC interface, that is configured to communicate NFC signals with a first external device; and a logic controller in data communication with the data interface, wherein the passive NFC interface and the data interface automatically share both a single memory and necessary authentication data.
