• Manufacturer Part Number: SSD2119
• Description: 320 Rgb X 240 Tft Lcd Driver Integrated Power Circuit, Source And Gate Driver And Ram
• Manufacturer: Crystalfontz America, Inc.,

DC[3:0]: Set the step-up cycle of the step-up circuit for 262k-color mode (CM = V
driving ability of the step-up circuit increases, but its current consumption increases too. Adjust the cycle taking into
account the display quality and power consumption.
AP[2:0]: Adjust the amount of current from the stable-current source in the internal operational amplifier circuit. When
the amount of current becomes large, the driving ability of the operational-amplifier circuits increase. Adjust the current
taking into account the power consumption. During times when there is no display, such as when the system is in a sleep
mode.
