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
www.DatadShoecetu4mU.ceonmts 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.

• VDD is on Pin 2. This is a + 5 Volts supply.
• VN is on Pin 3. This is a (– 10 to –5) Volts supply.
• VLED is on Pin 8. This is a +5 Volts supply for the LED light source.
Note: Power return for the LED light source is GLED on Pin 7 and the ground return for
the CIS modules is pin 5.
Video Output:
DIGOUT is on pin 1 of the I/O connector. This is the digital video output from the CIS
module. Reflection off the dark target produces a digital signal of “0” level, while the white
reflection off the white target produces a digital level of “one”. The amplitudes of the white
and dark are listed in the table below:

(1) The Tint is specified with a 2.0 MHz clock frequency. In operation the time
constants in the reference generator is set to match the initial exposure time,
hence the time constant will determine the optimum integration time. Note the
integration time is also a function of the clock frequency. Accordingly it is highly
recommended that the parameters be factory adjust for the specific
applications.
