IC Card Interface ICs  
IC Card Interface ICs  
with Built-in Low Noise LDO Regulator  
BD8918F,BD8918FV,BD8919F,BD8919FV  
No.09056EDT01  
Overview  
This is an interface IC for a 5V smart card.  
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
