General Description

IT7010C/H features a 240-channel segment driver, and was designed to drive a color 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 segment signals are made to run at a high speed to be driven at a low voltage, reducing the required power consumption considerably. Additionally, the power standby function supported in the device can also help reduce the overall power consumption while the LCD panel is not actively in use.

The device provides 8 data bits, and the allowed shift clock speed is up to 25MHz and 40MHz for 3V logic drive voltage and 5V LCD drive voltage respectively.

The device is available in two packages: 267-TCP and CHIP FORM (368 bumps).
