SDHI

Note 1. In the G-version products, the AC characteristics are measured by setting the drive capacity control register 2 corresponding the

SDHI_CLK-C pin as a high-speed interface high-drive output.

Note 2. When a letter “-A”, “-B”, etc. to indicate group membership is appended to the pin name, each pin is recommended to use in

combination with the pins in the same group. All SDHI AC timings are measured in combination with the pins in the same group.

SDHI Timing

Conditions: VCC = AVCC0 = AVCC1 = VCC_USB = VBATT = 2.7 to 3.6 V, 2.7 V ≤ VREFH0 ≤ AVCC0,

VSS = AVSS0 = AVSS1 = VREFL0 = VSS_USB = 0 V,

PCLKA = 8 to 120 MHz, PCLKB = 8 to 60 MHz, Ta = Topr,

Output load conditions: VOH = 0.5 × VCC, VOL = 0.5 × VCC, C = 30 pF,

High-drive output is selected by the driving ability control register.*1
