ABSTRACT:
An electronic device has a microprocessor operable in a plurality of modes including a memory update mode, a nonvolatile memory and a wireless communication interface for receiving data over a wireless communication channel. In one embodiment, the electronic device includes a wake-up or timer circuit for automatically placing the electronic device in a wireless memory update mode. Data received by said wireless communication interface is stored in the nonvolatile memory by the microprocessor in response to receipt of the data while the microprocessor is in memory update mode. A programming unit for transmitting update data has a microprocessor, a wireless communication interface and a memory containing update data. A communication path is established between the programming unit and the electronic device. A system for updating data stored in a nonvolatile memory of a plurality of electronic devices includes a programming unit and a plurality of electronic devices. A method of updating data stored in the nonvolatile memories of a plurality of electronic devices includes placing a programming unit in proximity to the plurality of electronic devices and activating a wireless update routine in the programming unit.
