test pin; leave open-circuit in the application
delayed attachment reference signal output for external pull-up resistor on pin D+ (an internal
1.5 k pull-up resistor is already embedded in the chip)
test pin; leave open-circuit in the application
connect to GND within the application; for programming the EPROM connect to V
as pin TEST (pin 22); also used for test purposes
data input/output from the card (C7); 14 k integrated pull-up resistor connected to V
test pin; leave open-circuit in the application
auxiliary I/O for C8 contact; 14 k integrated pull-up resistor connected to V
card presence detection input (active HIGH; no need for external pull-up)
auxiliary I/O for C4 contact; 14 k integrated pull-up resistor connected to V
cards ground (C5) Must be connected to GND
clock output (C30)
card supply output voltage (ISO C1 contact); must be decoupled with two 100 nF low ESR
ceramic capacitors to CGND
cards reset output (C2)
test pin input
output of the DC-to-DC converter (decouple with a 1 F capacitor to STGND)
DC-to-DC converter inductor connection (a Schottky diode should be tied to V
DC-to-DC converter ground connection
soft switched positive supply voltage (decouple with 10 F capacitor to GND)
positive supply voltage for the bus (4.2 to 5.5 V)
bus ground
USB D+ data line
USB D data line
