AR0835HS: 1/3.2-Inch 8 Mp CMOS Digital Image Sensor

Signal Descriptions

7. VDD_1V2 and VDD_PHY can be tied together.

8. HiSPi mode only: VDDSLVS_PHY is set to 0.4V externally. Alternatively, VDDSLVS_PHY

may be tied to 1.2V if the user chooses to have the HiSPi SLVS PHY TX voltage sup-

plied using the AR0835HS's internal 1.2V-to-0.4V regulator.

9. Register 31BE[2:3] can be used to program the option of internal of external regulator,

ON Semiconductor recommends using external regulator

10. ATEST can be left floating.

11. TEST pin must be tied to DGND.

12. VDD_1V8 is the OTPM read voltage.

Signal Descriptions

AR0835HS has 66 pads placed in a two-sided pad frame. It has only serial outputs. The

part may be configured as HiSPi with different bit depths. The pad description is tabu-

lated in Table 4:

Pad Descriptions

Pad Name

Pad Type

Description

Sensor Control

EXTCLK

Input

Master clock input; PLL input clock. 6 MHz - 27 MHz.

This is a SMIA-compliant pad.

GPIO0

Input/Output

General Input and one Output function include:

a. (Default Output) Flash

b. (Input) all options in GPI2

High-Z before XSHUTDOWN going high; default value is ‘0’ after all three

voltages in place and XSHUTDOWN being high.

After reset, this pad is not powered down since its default use is as Flash pin.

If not used, can be left floating.

GPIO1

Input/Output

General Input and 2 Output functions include:

a. (Default Output) Shutter

b. (Output) 3-D daisy chain communication output

c. (Input) all options in GPI2

High-Z before XSHUTDOWN going high; default value is ‘0’ after all three

voltages in place and XSHUTDOWN being high.

After reset, this pad is not powered-down since its default use is as Shutter

pin.

If not used, can be left floating.

GPI2

Input

General Input; After reset, these pads are powered down by default; this

means that it is not necessary to bond to these pads. Functions include:

a. SADDR, switch to the second two-wire serial interface device address (see

“Slave Address/Data Direction Byte” on page 17)

b. Trigger signal for Slave Mode

c. Standby

If not used, can be left floating.

GPI3

Input

General Input; After reset, these pads are powered-down by default; this

means that it is not necessary to bond to these pads. Functions include:

a. 3-D daisy chain communication input

b. All options in GPI2

If not used, can be left floating.

Two-wire Serial Interface

SCLK

Input

Serial clock for access to control and status registers.
