It works as a bidirectional signal buffer between a smart card and a controller. Also, it supplies 5V power to a smart card. With an electrostatic breakdown voltage of more than HBM; ±6000V, it protects the card contact pins. ●Features 1) 1 half duplex bidirectional buffers 2) Protection against short-circuit for all the card contact pins 3) 5V power source for the card (VCC) 4) Over-current protection for card power source 5) Built-in thermal shutdown circuit 6) Built-in supply voltage detector 7) Automatic activation/deactivation sequence function for card contact pin Activation sequence: driven by a signal from controller (CMDVCCB) Deactivation 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) Recommend frequency of crystal oscillator: 8MHz (BD8918F/FV), 16MHz (BD8919F/FV) 10) Programmable for card clock division of output signal: 1/1 and 1/2(BD8918F/FV), 1/2 and 1/4(BD8919F/FV). 11) RST output control by RSTIN input signal (positive output) 12) One multiplexed card status output by OFFB signal ●Applications Interface for CLASS A smart cards Interface for B-CAS cards ●Line up matrix Part No BD8918F BD8918FV BD8919F ...
