Electrical Characteristics
4.1.3
Test Conditions and Recommended Settings
Unless specified, AC timing parameters are specified for 15 pF loading on i.MX27/iMX27L pads. Drive
strength has been kept at default/reset values for testing. EMI timing has been verified with high drive
strength setting and 25 pF loads. SDHC timing has also been verified with high drive strength setting.
Unless otherwise noted, AC/DC parameters are guaranteed at operating conditions shown in Table 7.
