General Description:
This MOT is a motion tracing ASIC with high quality CMOS image sensor, DSP and UART protocol.
The sensor can track object smartly with sub-pixel accuracy and output the object features including center
coordinate, object size, object border, object shape, object vector, object aspect ratio, object label, object
brightness sum, object movement etc…. These object features can be transferred to external processor
through UART interface.
MOT performs gain and exposure setting and can be programmed by setting internal registers via UART.
By programming these internal register sets, we can change the function in CIS, DSP and UART, such as
frame rate, exposure control, object center resolution, and UART speed…etc.

Skip mode ( 100 fps is 1 skipped ) Current consumption typical 10mA, (maximum 13mA)
@27MHz @VDDMAIN=3.6V
Power Down: Typical 20uA, Max. 60µA ( wake up by UART ) @27MHz @VDDMAIN=2.8V
Current consumption estimate for operating at 16MHz @VDDMAIN=3.6V:
Power management mode
Frame rate (fps)
Current consumption (mA)
Fast Mode
120 fps
10.7mA
Skip Mode
60 fps (skip 1 frame)
7.9mA
Skip mode: User can set how many frame data to ignore to save power based on fast mode frame rate.
However, Vsync signal is keeping ouput based on the Fast mode frame rate. For example, when user set
skip n frames, the current consumption will become: ((10.5*x/27 + 4.5) + (1*x/27 + 4.5)*n)/(1+n). And
sensor will output 1st frame data, then skip n frame data w/o data output. Where n= skip frame number;
x = system clock (Mhz)

5.1 Baud Rate Control
Baud Rate (bps) = Sysclk/Reg_Div, which Reg_Div is a 12 bits divider.
Default baud rate is 19200bps @27Mhz system clock.
Maximum baud rate = 5Mbps
The minimum bit rate is limited by the formula, object data count * object number * frame rate * 12 bps.
