General Description
ICM-532B is a single-chip, CIF resolution, digital color PC camera with integrated data compression, line
buffer and Full Speed USB 1.1 interface. All the image processing functions (color interpolation, color
correction, auto white balance, auto exposure, auto anti-flickering, sharpening) are performed by software in
the host computer. It incorporates a 352x288 sensor array operating at 6 ~ 30 frames per second in
progressive manner. Each pixel is covered by a color filter, which forms a “Bayer pattern.” Correlated
double sampling is performed by the internal ADC and timing circuitry. The raw data can be adjusted with
digital gain. The raw data is compressed using a proprietary compression scheme. The compression allows
video out in 8-bit compressed data format through USB 1.1 with 30 frames per second video capability. For
higher frame-rates, sub-sampled or cropped QCIF (176x144) modes are available that support 35 frames per
second.
8 Pins are supplied that can be programmed by the driver as general purpose I/O pins, with individually
selectable output enables. During power-up, the internal control registers can be loaded from an external
serial EEPROM. This allows customization of Vendor ID and Product ID, as well as initialization of other
device parameters.
The 48 MHz clock required for the ICM-532B is provided by an on-chip phase-lock loop that is driven by an
external 6 MHz crystal oscillator. Using a PLL reduces power dissipation, electrical noise and the cost of the
crystal. It also reduces the need for EMI shielding that would be required if a 48 MHz oscillator were used.
The highest frequency external signal is the 12Mbps on the differential USB data pins.
