Electronic device removably mounted on portable terminal equipment
First Claim
1. An electronic device which is removably mounted on portable terminal equipment, the electronic device comprising:
- a communication control circuit configured to perform radio communications with an external device in a state in which the electronic device is mounted on the portable terminal equipment;
a determining section configured to determine setting contents for the communication control circuit corresponding to the portable terminal equipment on which the electronic device is mounted;
a setting section configured to make settings for the communication control circuit based on the setting contents determined by the determining section; and
a communicating section configured to perform data communications with the portable terminal equipment on which the electronic device is mounted,wherein the determining section determines setting contents corresponding to a communication protocol used for radio communication by the communication control circuit based on equipment information acquired from the portable terminal equipment by use of the communicating section, andwherein the setting section sets a communication protocol for the communication control circuit based on the setting contents corresponding to the communication protocol determined by the determining section.

Abstract
A contact less function chip includes a communication control circuit for contact less communication and a memory which stores setting data items of various communication protocols for contact less communication applied to the communication control circuit for contact less communication. When the contact less function chip is mounted on a mobile telephone, it acquires equipment information of the mobile telephone, determines a communication protocol for contact less communication to be preferentially performed based on the equipment information of the mobile telephone and makes a communication setting for the communication control circuit according to setting data of the communication protocol which is determined to be preferentially performed.
