TCM5040T
1/4-inch 330 k-Pixel CMOS Image Sensor
with Built-in ADC fo r VGA
The TCM5040T is a B/W CMOS image sensor with a built-in
ADC for VGA. It outputs a signal for each pixel in sequence every
1/30 s. (This is known as progressive scanning.)
This element is equipped with 492 vertical and 660 horizontal
signal pixels, and the image size conforms to the 1/4-inch optical
format.
Use of the CMOS process enables low power-consumption using
a single power supply voltage. The device is perfect for use as an
image input device for machine vision, 2-D barcode use and
surveillance camera.

Block Diagram
The SGMODE pin can be used to select either internal or external synchronization.
The SGMODE pin is pulled down. When the SGMODE pin is open, External Synchronization Mode is selected.
When the SGMODE pin is High, Internal Synchronization Mode is selected.
In External Synchronization Mode, the HPA and VDD sync. signals and the electronic shutter signal are input
from an external source. In Internal Synchronization Mode, HD and VD sync. signals are output and the value of
the electronic shutter signal must be set using a command.

Note 2: Standard conditions for measuring sensitivity
· 100 nt
· Other conditions are based on Note 3.
Note 3: Standard conditions (TC = 60°C centigrade) as follows
· Light source: 3200 K, halogen light box
· Optical filter: IR cut filter (cut in half at 650 nm)
· Optical lense: Fujinon f = 25 mm, F number 2.8
· Standard signal level: Output = 250 mV
· Driving conditions: frame rate = 30 fps, electronic shutter OFF
The analog output level can be estimated as follows when a ´1 gain DA converter (500 mVpp) is used.
Optical lens performance influences sensor characteristics.
(1) F number: Less than F2.8 is recommended to maintain a high level of sensitivity and an acceptable
S/N ratio.
(2) Exit pupil may influence shading level.
