ZR 36506 Pinout
Pin Number
Signal
I/O Description
14
PWR1
I
MSbit of Device Power Code. The voltage level in
this input (Vdd or GND) is used by the ZR36506 as
the MSbit of the Device Power Code for the USB
Device Descriptor. If an external EEPROM exists,
this input is ignored.
7
RESIN
I
Power-On Reset input. This input is of Schmitt-
Trigger type, and is active low. It is recommended to
use a power-on RC network for proper Reset.
15
SENS
O
Serial control Enable Signaling. This pin has an Open
Drain output. It should be connected to an external
3.3-10 K
Pull-Up resistor. This output is set to
High-z while in Suspend or Power-Down modes.
16
IICDT
I/O Camera-Control Data I/O (supports some commonly
used serial protocols). This pin has an Open Drain
output. It should be connected to an external 3.3-10
K
Pull-Up resistor. This output is temporarily set to
High-z while in the Suspend or Power-Down
position.
17
IICCK
O
Camera-Control Clock output (supports some
commonly used serial protocols). This pin has an
Open Drain output. It should be connected to an
external 3.3-10 K
Pull-Up resistor. This output is
temporarily set to High-z while in the Suspend or
Power-Down position.
10
PWR_DWN
O
Camera Power-Down control. This is an Open Drain
output, which is used to switch power On or Off to
the camera and/or external circuit (using an external
switching P-MOSFET transistor). While in Reset, the
output is set to High-z (Off). It is set to High-z in
Suspend mode, and remains High-z when resuming
from Suspend.
11
SUSPND
O
USB Suspend mode control. This is an Open Drain
output. A Power-On Reset or a USB-Reset turn the
output to active low It is set to High-z in Suspend
mode, and is turned to active low when Resuming
from Suspend.
31
CAPTRN
I
Capture Button input. A Schmitt-Trigger input with
an internal Pull-Up resistor When forced to '0', the
host computer is automatically informed that a video
frame capture was requested by the user.
