Patent ID: 6840454

Claim:
A portable article of the smart card type, the article comprising firstly a body and secondly an integrated circuit chip ( 9 ), said integrated circuit chip ( 9 ) having a central processor unit (CPU) connected via a data and address bus to memories (ROM, RAM, EEPROM), and further including at least a first contact pad (VCC) suitable for providing the chip ( 9 ) with a power supply voltage, a second contact pad (GND) suitable for grounding the chip ( 9 ), a third contact pad (D+) and a fourth contact pad (D−), said contact pads (VCC, GND, D+, D−) being electrically connected respectively to a first contact area (C 1 ), a second contact area (C 5 ), a third contact area (C 4 ), and a fourth contact area (C 8 ) of a set of eight contact areas (C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7 , C 8 ) flush with a surface of the article body, the third and fourth contacts pads (D+, D−) being connected to an interface of the chip ( 9 ) and being suitable for providing data transmission under the control of the central processor unit (CPU), the chip ( 9 ) further including a fifth contact pad (VPP), a sixth contact pad (RST) suitable for resetting the chip ( 9 ), a seventh contact pad (CLK) suitable for providing the chip with a clock signal, and an eighth contact pad (I/O) suitable for inputting and outputting data signals using an asynchronous protocol, said sixth, seventh, and eighth contact pads (RST, CLK, I/O) being connected electrically respectively to a sixth contact area (C 2 ), a seventh contact area (C 3 ), and an eighth contact area (C 7 ) of the set of eight contact areas flush with the surface of the article body.
