Integrated circuit for protocol control
First Claim
1. An integrated circuit for protocol control to be incorporated into an apparatus capable of handling digital money defined as a symbol of electronic currency, said integrated circuit being configured by integrating, on one chip, a storage section for storing a plurality of control programs, one prepared for each of a plurality of protocols for a plurality of kinds of digital money different in mode from each other;
- a processing section for controlling the handling of said plurality of kinds of digital money, different in mode, in the apparatus by executing one control program corresponding to a mode of digital money that is to be handled in the apparatus into which said integrated circuit is to be incorporated, which one control program is assigned from said plurality of control programs stored in said storage section; and
an interface circuit connected to an external circuit including at least one of an external processing section and an external storage section to fulfill an interface function between said external circuit and said processing section.

Abstract
A protocol control integrated circuit configured by integrating, on one chip, hardware and control programs necessary for conducting data interchange through communications with portable type mediums, and used in common among various types of apparatus. Thus, the integrated circuit is constructed by integrating, on one chip, a storage section for storing a control program prepared for protocols for a plurality of digital money different in mode from each other, a processing section for controlling the handling of the plurality of digital money, different in mode, by running the control program stored in the storage section, and an interface circuit connected to an external circuit including at least one of an external processing section and an external storage section for fulfilling an interface function between the external circuit and the processing section. Further this invention is applicable to various types of transaction apparatus capable of handling, for example, digital money and credit transactions.
