Reset Voltage: 2.9 V 
Package: 5 pin SOT-23-5
Operation Outline: When 3.3V power starts up, it emits about 50ms reset pulse after detecting 2.9V.

Operation Outline: By pressing the Function Switch you can stop access to the SD card and then remove it.

 Operation Outline: By pressing the Factory Default Reset Switch, all of the camera's settings are reset to their factory default
settings.

Operation Outline: Restart SW (SW103) is connected to RESET IC for a manual reset, and the hardware is reset when this SW
is pressed.

Operation Outline: IC404 is RTC (Real Time Clock), and is used for time setting of image transfer, etc. This is backed up by a
lithium battery (BAT501) even at the time of power OFF. 
There is an RTC block inside IC101, and this inside RTC block operates during the existence of electricity by importing the clock
data from IC404 at the time of power ON.

Power Supply Voltage: 3.3 V 
Operation Outline: An SD memory card control block is included on IC101, and used by connecting an SD card slot (CN301)
There is a green LED (LED301) near the SD card slot, and it lights while the SD card is being accessed.

• IC201 is a CMOS image sensor with approx. 320 thousands pixels, and outputs the image signal (DAT0-9) in VGA size

(640x480).

• IC201 outputs Pixel clock (PCLK_13.5MHz), VD and HD signals based on the timing of input Pixel clock (CLOCK_27 MHz) from

the CPU board.

• IC201 is controlled by CPU using the serial signal (ISCK, ISDA).
• IC201 requires 3.3 V, 1.8 V from CPU board.
• IC205 is used as the 1-Kbit EEPROM for the setting of images.
• IC205 is controlled by CPU using the I2C(ISCK, ISDA) signal.
• IC205 requires 3.3 V for the power supply of Camera Unit. 3.3V is input from CPU unit.
