Remark
Note 1
Note 2
Note 1: A build-in power on reset circuit for VDC and VCCI is provided within the integrated LCD driver IC.
The LCD module is in power save mode in default, and a standby releasing is required after VCCI
power on through serial control. Please refer to the register STB setting for detail.
Note 2: The power supply of digital interface, VCCI, is for the 1.8V digital interface requirement in the
future. These digital signals are DCLK, HSYNC, VSYNC, D7~D0, CS, SDA and SCL. If the
digital interface is in the level of 3.3V, please short the power pin VDC and VCCI to 3.3V. In other
words, no matter the voltage level of VCCI is 1.8V or 3.3V, the voltage level of VDC needs to be
kept 3.3V.

Note 1: Test Condition: 8colorbar+Grayscale pattern, UPS051 mode, DCLK=24MHz, Frame rate: 60Hz,
other registers are default setting
Note 2: Test Condition: 8colorbar+Grayscale pattern, UPS052 320x240 mode, DCLK = 24MHz, other
registers are default setting
Note 3:In standby mode, digital signals DCLK, HSYNC, VSYNC, D7~D0, CS, SDA and SCL are stopped.
Note 4: VGH and VGL are output voltages of integrated LCD driver IC.
Note 5: The brightness of LCD panel could be adjusted by the adjustment of the AC component of VCOM.
