ASX340CS: 1/4-Inch Color CMOS NTSC/PAL Digital Image Sensor

Pin Descriptions and Assignments

Notes:

1. The reason for defining the default state as logic 0 rather than high impedance is this: when wired

in a system (for example, on ON Semiconductor’s demo boards), these outputs will be connected,

and the inputs to which they are connected will want to see a valid logic level. No current drain

should result from driving these to a valid logic level (unless there is a pull-up at the system level).

2. These pads have their input circuitry powered down, but they are not output-enabled. Therefore,

they can be left floating but they will not drive a valid logic level to an attached device.

PIXCLK

High impedance

Driven, logic 0

Output. This interface disabled by default.

See Note 1.

DOUT7

DOUT6

DOUT5

DOUT4

DOUT3

DOUT2

DOUT1

DOUT0

DOUT_LSB1

High impedance

Input/Output. This interface disabled by

default. Input buffers (used for GPIO function)

powered down by default, so these pins can

be left unconnected (floating). After reset,

these pins are powered-up, sampled, then

powered down again as part of the auto-

configuration mechanism.

DOUT_LSB0

High impedance

HIgh impedance

DAC_POS

High impedance

Driven

Output. Interface disabled by hardware reset

and enabled by default when the device starts

streaming.

DAC_NEG

DAC_REF

TDI

Internal pull-up enabled

Input. Internal pull-up means that this pin can

be left unconnected (floating).

TDO

High impedance

Output. Driven only during appropriate parts

of the JTAG shifter sequence.

TMS

Internal pull-up enabled

Input. Internal pull-up means that this pin can

be left unconnected (floating).

TCK

Internal pull-up enabled

Input. Internal pull-up means that this pin can

be left unconnected (floating).

TRST_N

N/A

Input. Must always be driven to a valid logic

level. Must be driven to GND for normal

operation.

FRAME_SYNC

N/A

Input. Must always be driven to a valid logic

level. Must be driven to GND if not used.

GPIO12

High impedance

Input/Output. This interface disabled by

default. Input buffers (used for GPIO function)

powered down by default, so these pins can

be left unconnected (floating).

GPIO13

High impedance

Input/Output. This interface disabled by

default. Input buffers (used for GPIO function)

powered down by default, so these pins can

be left unconnected (floating).

ATEST1

N/A

Must be driven to GND for normal operation.

ATEST2

N/A

Must be driven to GND for normal operation.
