General Description
The PI331MC-DR is a contact image sensor, CIS, module with an additional on board circuit that digitizes the analog pixels from the CIS image sensor to a “background-tracking”, two-level digital output signals. It is based on CIS module, the PI305M-A6 manufactured by PIC, but with a shorter read length of 89 mm. Hence, its performance is equivalent to the PI305M-A6 that uses MOS image sensor technology to gains its high-speed performance and high sensitivity. The PI331MC-DR is suitable for scanning documents with width of 89 mm and with resolution of 11.8 dots per millimeter. Its has a broad applications, but specially designed for the following areas:

• Where data compression is required, such as in data transmissions.
• Where component pin-out count must be kept to a minimum.

Key Features
• Light source, lens, and sensor are integrated into a single module
• 11.8 dpm resolution, 89 mm scanning length
• Up to 600 msec/line scanning speed, with 2 MHz pixel rate (See Table 3, Note 3.) (Other speeds are also available)
• Wide dynamic range
• Two-Level Tracking Digital Output (“Dynamic Threshold Digitizer”)
• Red light source 660nm (Other colors are available)
• Compact size @ 13 mm x 25.6 mm x 102 mm
• Low power
• Light weight
