DESCRIPTION
PWROFF 1 control input for entering the Off mode (active LOW)
S1 2 capacitor connection for the DC-to-DC converter (between S1 and S2)
PGND
3 power ground
S3 4 capacitor connection for the DC-to-DC converter (between S3 and S4)
VDDP
S4
5 power supply voltage
6 capacitor connection for the DC-to-DC converter (between S3 and S4)
S2 7 capacitor connection for the DC-to-DC converter (between S1 and S2)
VUP
8 DC-to-DC converter output (must be decoupled with 100 nF to ground)
I/O 9 input/output to and from the card reader (C7I); see Fig.7
SGND
10 signal ground
CLK 11 clock output to the card reader (C3I)
VCC
RST
12 supply voltage to the card reader (C1I)
13 reset output to the card reader (C2I)
VDDS
DEL
14 signal supply voltage
15 external capacitor connection for the delay on voltage supervisor
PRES
16 card presence indication input (active LOW); note 1
SIMI/O
VDDI
SDA
SCL
SIMERR
SAD0
SAD1
17 input/output to and from the microcontroller (internal 20 kΩ pull-up resistor connected to VDDI)
18 supply voltage for the interface signals with the system
19 I2C-bus serial data input/output
20 I2C-bus serial clock input
21 interrupt output (active LOW; internal 100 kΩ pull-up resistor connected to VDDI)
22 I2C-bus slave address selection input
23 I2C-bus slave address selection input
SIMCLK
24 external clock input
Note
1. Card presence input with negative current source. To be used with the card reader switch connected to VDDS
or VDDP. The switch is normally closed when the card is not present. If the switch connection is open-circuit or pin 16
is not connected, then the interface will always detect a present card (see Fig.7).
