DESCRIPTION
1 8xC51 general purpose I/O port (USB_MC_READY)
2 8xC51 general purpose I/O port (USB_CLK_EN_N)
3 8xC51 general purpose I/O port (USB_RESET_N)
4 8xC51 general purpose I/O port (USB_SOFTCONNECT_EXT)
5 8xC51 general purpose I/O port (available for the application)
6 8xC51 general purpose I/O port (available for the application)
7 reset input (active HIGH, integrated pull-down resistor to ground)
8 test pin; leave open-circuit in the application
9 test pin; leave open-circuit in the application
10 delayed attachment reference signal output for external pull-up resistor on pin D+ (an internal
1.5 kpull-up resistor is already embedded on-chip)
11 test pin; leave open-circuit in the application
12 connect to GND within the application; for programming the EPROM connect to VDD as well
as pin TEST (pin 22); also used for test purposes
13 data input/output from the card (C7); 14 kintegrated pull-up resistor connected to VCC
14 test pin; leave open-circuit in the application
15 auxiliary I/O for C8 contact; 14 kintegrated pull-up resistor connected to VCC
16 card presence detection input (active HIGH; no need for external pull-up)
17 auxiliary I/O for C4 contact; 14 kintegrated pull-up resistor connected to VCC
18 cards ground (C5) Must be connected to GND
19 clock output (C30)
20 card supply output voltage (ISO C1 contact); must be decoupled with two 100 nF low ESR
ceramic capacitors to CGND
21 cards reset output (C2)
22 test pin input
23 output of the DC-to-DC converter (decouple with a 1 µF capacitor to STGND)
24 DC-to-DC converter inductor connection (a Schottky diode should be tied to VUP)
25 DC-to-DC converter ground connection
26 soft switched positive supply voltage (decouple with 10 µF capacitor to GND)
27 positive supply voltage for the bus (4.2 to 5.5 V)
28 bus ground
29 USB D+ data line
30 USB Ddata line
31 connection for an external capacitor to ground determining the Power-on reset pulse width
(typ 1 ms per 2 nF)
32 8xC51 general purpose I/O port/serial input port (available for the application)
33 8xC51 general purpose I/O port/serial output port (available for the application)
34 8xC51 general purpose I/O port/external interrupt 0 (used by the ISO UART))
35 8xC51 general purpose I/O port/external interrupt 1 (used by the USB interface)
