Description

general purpose I/O

general purpose I/O

supply voltage

ground connection

shut-down signal input (active LOW, no internal pull-up)

connection for an external capacitor determining the

power-on reset pulse width (typically 1 ms per 2 nF)

data input/output to/from the card (C7); 14 kΩ integrated

pull-up resistor to VCC

card presence detection contact (active HIGH); do not

connect to any external pull-up or pull-down resistor; use

with a normally open presence switch (see details in

Section 8.13)

card ground (C5); connect to GND in the application

clock to the card (C3)

card supply voltage (C1)

card reset (C2)

output of the DC-to-DC converter (low ESR 220 nF to

PGND)
