NAME
FUNCTION
INPUTS/OUTPUTS
1
C4
I2C_SEL
I2C Select Input. I2C_SEL must be connected to VIO or GND at power-up. Drive
I2C_SEL low to disable I2C control and drive I2C_SEL high to enable I2C control.
2
A2
SCL
I2C Serial-Clock Input. SCL is +3.6V tolerant and the high threshold is set by VIO. If
the I2C interface is not used, connect SCL to GND.
3
B4
SDA
I2C Serial-Data I/O. SDA is +3.6V tolerant and the high threshold is set by VIO. If the
I2C interface is not used, connect SDA to GND.
4
A3
ADD
I2C Address Selection Input. Connect ADD to VIO or GND to select between two I2C
slave addresses: (GND = 1110 000Xb and VIO = 1110 001Xb).
6B6
BERR/INT
Card Reader Error/Interrupt Output. BERR/INT becomes BERR for simple control and
INT for I2C control. BERR/INT goes low to indicate an error in Card Reader mode
during simple control and asserts for enabled interrupts during I2C control.
7A7
BUSY
Busy Output. BUSY asserts low to indicate device is in Card Reader mode.
8
C6
MODE
Card Reader/Pass Thru Mode Select Input. MODE is only active during simple
control. Drive MODE low to enable Pass Thru mode and drive MODE high to enable
Card Reader mode. For I2C control, MODE must be connected to GND.
9B7
RST
Reset Input. Drive RST low to reset the internal registers to default values and put all
outputs in high impedance. Connect RST to VIO for normal operation.
25
E6
FREF
Frequency Input. FREF is the clock input (12MHz/13MHz/19.2MHz/26MHz) for the
internal logic and USB PHY. FREF can accept a square-wave or sine-wave clock. An
internal clock squaring circuit can be enabled or disabled through I2C. In simple
control, the internal clock squarer is enabled by default.
27
F5
RREF
Reference Resistor. Connect a Bias Resistor 6.19k
Ω ±1% from RREF to GND.
USB INTERFACE
22
G7
CD+
USB Analog Switch/Hi-Speed USB Transceiver. CD+ connects to D+ on the USB
connector.
21
F7
CD-
USB Analog Switch/Hi-Speed USB Transceiver. CD- connects to D- on the USB
connector.
20
G8
HD+
USB Analog Switch. HD+ connects to D+ on the host side.
19
F8
HD-
USB Analog Switch. HD- connects to D- on the host side.
28
E5
KVBUS
USB Bus Power-Supply Detection Input. Connect a resistor-divider between USB
VBUS, KVBUS, and GND.
SD CARD INTERFACE
13
C8
CDAT1_0
SD Card 1 Data Bus Analog Switch/Card Reader Interface. CDAT1_0 connects to
DAT0 on the SD card.
12
B8
CDAT1_1
SD Data Card 1 Bus Analog Switch/Card Reader Interface. CDAT1_1 connects to
DAT1 on the SD card.
11
C7
CDAT1_2
SD Data Card 1 Bus Analog Switch/Card Reader Interface. CDAT1_2 connects to
DAT2 on the SD card.
