General Description

IT7012 features a 320-channel segment driver, which consists, and was designed to drive a mono dot matrix STN-LCD panel, yet requires low voltages.

In power, the device only requires a low 5V LCD drive voltage, and a low 3V-logic drive voltage in logic portion. In terms of power consumption, the device is able to reduce the required voltage level and power consumption considerably. Additionally, the power standby function supported in the device can also help to reduce the overall power consumption while the LCD panel is not actively in use.

Packaged in a fine-pitch flex tape-carrier package (Flex-TCP) and CHIP FORM (433 bumps), the cost-effective IT7012 provides 4 or 8 data bits, and the shift clock speed allowed is up to 6.5MHz and 8MHz for 3V logic drive voltage and 5V LCD drive voltage respectively.

 In addition, users are allowed to select either 320-channel or 240-channel output mode by conveniently changing the mode according to what panel resolution they have.
