LCD-TFT controller (LTDC) characteristics

Unless otherwise specified, the parameters given in Table 92 for LCD-TFT are derived from

tests performed under the ambient temperature, Fpclk4 frequency and VDD supply voltage

summarized in Table 13: General operating conditions, with the following configuration:

•

LCD_CLK polarity: high

•

LCD_DE polarity: low

•

LCD_VSYNC and LCD_HSYNC polarity: high

•

Pixel formats: 24 bits

•

Output speed is set to OSPEEDRy[1:0] = 11

•

Capacitive load C = 30 pF

•

Measurement points are done at CMOS levels: 0.5×VDD

•

I/O compensation cell enabled
