22 / 70 page  i.MX28 Applications Processors Data Sheet for Consumer Products, Rev. 1 22 Freescale Semiconductor Output sink current1 (dc) gpio IOL – Low 3.8 — mA IOL – Medium 7.7 — mA IOL – High 9.0 — mA Output source current1 (dc) gpio_clk IOH – Low -9.2 — mA IOH – High -15.2 — mA Output sink current1 (dc) gpio_clk IOL – Low 7.6 — mA IOL – High 12.0 — mA 10-K pull-up resistance2 Rpu10k 8 12 K Ω 47-K pull-up resistance2 Rpu47k 39 56 K Ω 1 The conditions of the current measurements for all different drives are as follows: IOL: at 0.4 V IOH: at VDDIO * 0.8 V Maximum corner for 3.3 V mode: 3.6 V, -40 °C, fast process. Minimum corner for 3.3 V mode: 3.0 V, 105 °C, slow process 8 gpio pins (LCD_D0-D7) and 2 gpio_clk pins (LCD_DOTCLK and LCD_WR_RWN) simultaneously loaded. 2 See the i.MX28 reference manual for detailed pull-up configuration of each I/O.
