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.

2. Functional Description
ICM-532B is a single-chip USB digital color imaging device. It includes a 352x288 sensor array, 352 column-level ADC, and correlated double sampling circuitry. All the programmable parameters are set by writing through the USB interface which can address the register file consisting of 8-bit registers. The internal CIF image sensor is based upon the ICM-102B. The output format is USB 1.1 compatible compressed video data using a single ISOCHRONOUS channel. Dead pixels and dead columns are

2.1. Image Array
The image array consists of 352x288 pixels. Each pixel has a light sensitive photo diode and a set of control and transfer transistors. At the beginning of the cycle, a row of pixels is pre-charged to its maximum value. Then they are exposed to light for several lines worth of time and sampled by the ADC. Correlated double sampling (CDS) is performed by subtracting the reset value (sampled right before sampling the signal) from the signal value. The purpose of CDS is to eliminate the point-wise fixed pattern noise (FPN). The output of CDS is approximately proportional to the amount of received light, ranging from 0 to 255.
2.2. Color Filter
Each pixel is covered by a color filter. They form the Bayer Pattern as shown in Figure 2. (Row 0, Column 0) is covered by a Red filter, (Row 0, Column 1) and (Row 1, Column 0) by Green filters, and (Row 1, Column 1) by a Blue filter. Since each pixel only gets part of the frequency band, the data needs further processing (i.e., color interpolation and color correction) in order to approximate the full visible spectrum.

over-exposed or under-exposed. To accommodate for different brightness, the user may change the exposure time or digital gain by adjusting the AD_EXPOSE_TIMEH and AD_EXPOSE_TIMEL. The exposure time is measured in terms of the time to read out one line of data, which is equal to 125 us (assuming the line length is 500). If the number of lines per frame is set at 320 (the default), the exposure time can vary from 1 to 319 lines. In addition, the user can adjust bit 7 to 5 of register AD_EXPOSE_TIMEH to digitally boost the output value by 1 to 64 times @ 2N for all pixels. Furthermore, users can adjust registers AD_M1_L, AD_M1_H, AD_M2_L, AD_M2_H, AD_M3_L, AD_M3_H, AD_M4_L, AD_M4_H, to optimize the RGB gain (from 1/256 to 64) of the 4 Bayer pattern pixels separately.
2.4. Output Format
During normal operation, the output format is 8-bit compressed data that ranges from 0 to 255. This data is transmitted with a USB Transceiver using Isochronous packets. The video quality is related to the size of the packets, with 1023 bytes/packet generating the highest quality image. The packets are received, decompressed, and color processed by a host PC. A typical configuration is to connect ICM-532B to a USB enabled PC. When operated at 24 fps CIF, the USB clock is 48 MHz and the Video data clock is 4MHz. When operated at 30 fp, the Video data clock is 6MHz. The line and frame timing can be adjusted through registers AD_WIDTH and AD_HEIGHT.
3. Control Registers
Registers may be configured using either the USB Command/Control Channel, or the Serial interface. The result is unpredictable if both interfaces are used simultaneously. USB access should be made using a Standard Vendor Type Device Request. For a write, if the Length field value is 0, the two bytes in the Value field are written into two registers starting at the Index field value. For all other Length field values, the data stage transfers the requested number of bytes starting from the Index field value. The data transfer Length must not be larger than 8 bytes.
The 7-bit Serial ICM-532B device address is 0x21. ICM-532B can operate in either Serial master mode or slave mode right after power up, depending on the pull-up or pull-down of the GPIO[1] pin. When GPIO[1] is pulled low during power-up, ICM-102B's Serial interface is operated as a slave device, waiting to be controlled by an external master such as a microprocessor. When GPIO[1] is pulled high

during power-up, the Serial interface will first act as a master device, trying to read from an external EEPROM (24C02/04/08/16). The first word read will indicate the number of bytes to transfer from the external EEPROM. After transferring these bytes, or failing to access an external device, the ICM-532B will behave like a slave device. The external EEPROM is addressed at address 0x50, and must be 3.3v compatible.

*These registers are updated at the next falling edge of VSYNC after register UPD is set. The occurrence of the update is marked in the video output by clearing bit 7 of the packet header. i.e. 80 => 00. This bit remains set until register UPD is cleared.
4. GPIO 4.1. General Purpose I/O pins
There are 8 pins that can be programmed by the user as general purpose Input/Output pins. Three of the pins are required to have pull-up or pull-down resistors attached to select device functionality at the rising edge of NRST. 1. Special Purpose: GPIO[0] Pull-up. It is possible to configure this output as an active low power-down pin, driven by the USB controller Suspend signal. When so configured, all external power except pins 4, 33, and 43 may be removed while this pin is driven low. It is also possible to configure this output as an active low power-on pin, connected to an external LED. When so configured, an external LED with 8ma current limiting resistor will be on

unless the device is in Suspend state. GPIO[1] Pull-up. To enable external Serial EEPROM for register loads, Pull-down to disable this feature. GPIO[2] Pull-up. To select crystal oscillator clock source. Required condition 2. General Purpose: The other 5 GPIO pins have no Pull-up/Pull-down requirements. All of these pins default to inputs at device reset. If the pins are to remain unused, an external pull-up is recommended to prevent the inputs from floating. To use an external switch, use a pull-up, and connect the switch between the GPIO pin and ground, and poll the selected pin in register 58. The pull-up will return a high value, and a switch event will return a low value.
5. Programming 5.1. Special considerations
There are several registers that need to be correctly programmed for device operation. If custom Vendor ID/Product ID values are required, these registers should be programmed by an external Serial EEPROM before the USB controller accesses the part. It is recommended that the Vendor ID and Product ID registers be programmed first. This allows the correct values to be set before the USB configuration after power-up. After that, the driver can look for a specific register value to indicate the end of Serial programming. During the initialization phase, if an external EEPROM is used, care must be taken by the driver to not accesses registers while the EEPROM is transferring data. The driver software should delay an appropriate time before accessing the registers. Expansion RAM: To access the internal 256Byte expansion RAM, load the RAA register with the desired address, and read or write the RAD register. Device Programming: The maximum size of a USB data transfer is 8 bytes. Transfers larger than this will not read/write the correct data values.

6.2. Clocking
The ICM-532B clock is generated from an external low cost 6MHz crystal. The on-board PLL generates the required USB clock and the Video Clock. The nominal Video Clock rate is 8MHz. This rate can be altered by setting either the Fastclock ( *1.5 ) or Slowclock ( /2.0 ) register bits. Video Timing examples: At 8MHz, the Video clock generates 1 pixel every 250ns, a line (500 pixels) every 125us, and 8 lines every 1ms. This produces 8 lines to be packed into 1 USB data transfer, to make a 24 fps QVGA (352 x288) transfer rate. At 12MHz, the Video clock generates 1 pixel every 166.7ns, a line (600 pixels) every 100us, and 10 lines every 1 ms. This produces 10 lines to be packed into 1 USB data transfer, to make a 30 fps QVGA (320x240) transfer rate. At 12MHz, the Video clock generates 1 pixel every 166.7ns, a line (500 pixels) every 83.3us, and 12 lines every 1 ms. This produces 6 lines to be packed into 1 USB data transfer, to make a 35 fps QCIF (176 x 144) transfer rate.
