IC Card Interface ICs IC card interface ICs with Built-in DC / DC Converter No.09056EAT02 BD8904F, BD8904FV, BD8905F, BD8906F, BD8906FV, BD8907F Overview BD8904F, BD8904FV, BD8905F, BD8906F, BD8906FV and BD8907F are an interface IC for a 3V or 5V smart card. It works as a bidirectional signal buffer between a smart card and a controller. Also, it supplies 3V or 5V power to a smart card. With electrostatic breakdown voltage of more than HBM: 6000V, it protects the card contact pins. Features 1) 3 half duplex bidirectional buffers 2) Protection against short-circuit for all the card contact pins 3) Card power source (VREG) of 3V or 5V 4) Overcurrent protection for card power source 5) Built-in thermal shutdown circuit 6) Built-in supply voltage detector 7) Automatic start-up/shutdown sequence function for card contact pin Start-up sequence: driven by a signal from controller (CMDVCCB) Shutdown sequence: driven by a signal from controller (CMDVCCB) and fault detection (card removal, short circuit of card power, IC overheat detection, VDD or VDDP drop) 8) Card contact pin ESD voltage 6000V 9) 2MHz - 26MHz integrated crystal oscillator 10) Programmable for clock division of output signal by 1, 1/2, 1/4, and 1/8 11) RST output control by RSTIN input signal (positive output) 12) One multiplexed card status output by OFFB signal Line up matrix Input Voltage Resistor to set VDD Operating Part No. Package voltage detector temperature VDD VDDP BD8904F External 2.7V - 5.5V 3.0V - 5.5V -40C - +85C SOP28 BD8904FV External 2.7V - 5.5V 3.0V - 5.5V -40C - +85C SSOP-B28 BD8905F External 2.7V - 5.5V 3.0V - 5.5V -25C - +85C SOP28 BD8906F Built-in 3.0V - 5.5V 3.0V - 5.5V -25C - +85C SOP28 BD8906FV Built-in 3.0V - 5.5V 3.0V - 5.5V -25C - +85C SSOP-B28 BD8907F Built-in 3.0V - 5.5V 3.0V - 5.5V -40C - +85C SOP28 Application Interface for smart cards Interface for B-CAS cards www.rohm.com 2009.07 - Rev.A 1/15 2009 ROHM Co., Ltd.
