Ballout and Interface
Micron Confidential and Proprietary
Note: 1. See “Standby Hardware Configuration” on page 153.
Table 3: Signal Description
Name Type Description Note
CLKIN Input
Master clock signal (can either drive the on-chip PLL or bypass it).
RESET# Input
Master reset signal, active LOW.
STANDBY Input
Controls sensor’s standby mode.
RSVD Input
Reserved for factory test. Tie to digital ground during normal operation.
AIN1 Input
Analog sampling and test. During normal operation, can be used to feed an
external analog signal to an ADC in the sensor core, in order to have the
signal sampled during horizontal blanking times and stored in a register.
AIN2 Input
Analog sampling and test. Can be used like AIN1 during normal operation.
AIN3 Input
Analog sampling and test. Can be used like AIN1 during normal operation.
SCLK Input
Two-wire serial interface clock.
S
ADDR Input
Selects device address for the two-wire serial interface. The address is 0x90
when SADDR is tied LOW, 0xBA if tied HIGH. See also R0x0D:0[10].
D
OUT0-DOUT7 Input
Eight-bit image data output or most significant bits (MSB) of 10-bit sensor
bypass mode.
1
FRAME_VALID Input
Identifies rows in the active image. 1
LINE_VALID Input
Identifies lines in the active image. 1
PIXCLK Input
Pixel clock. To be used for sampling D
OUT, FRAME_VALID, and LINE_VALID. 1
SDATA I/O
Two-wire serial interface data.
GPIO[7:0] I/O
General purpose digital I/O. Each bit can be independently configured as an
input or output. Outputs are controlled by register-programmable waveform
generator or by writing to registers GPIO_DATA_L and GPIO_DATA_H. Inputs
can be sensed by reading the same registers.
1
FLASH/GPIO11 I/O
GPIO11 or signal to control Xenon or LED flash. 1
GPIO10/STROBE I/O
GPIO10 or signal to control mechanical shutter. 1
GPIO9/D
OUT_LSB I/O
GPIO9 during normal IFP operation or data bit 1 in 10-bit sensor bypass mode. 1
GPIO8D
OUT_LSB0 I/O
GPIO8 during normal IFP operation or data bit 0 in 10-bit sensor bypass mode. 1
