JTAG/ICE
Software debug is accessed by a standard 20-pin JTAG connection. This allows connection to a standard USB-to-
JTAG in-circuit emulator such as SAM-ICE

Image Sensor
The CMOS image sensor, OV7740 from OmniVision, used in this reference design is a low-complexity, low-cost,
low-power, yet powerful sensor. It supports VGA (640x480) at up to 60 fps and QVGA (320x240) at up to 120 fps.
The OV7740 has standard interface output pins such as data, horizontal/vertical synchronization signals, pixel
clock output and main clock input. Interfacing between the CMOS image sensor and the SAM4S device is made
easy by means of the sensor interface (parallel capture mode). The SAM4S is able to sample data from the CMOS
image sensor without CPU intervention and transfer image data into internal or external memory.

PIR sensor
The PIR sensor (RE200B from Nicera) chosen for the reference design is a general purpose dual element. This
model satisfies user's cost reduction needs, keeping most dual element type performances at reasonable levels.
