SDSI

Note 1. 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 SDSI AC timings are measured in combination with the pins in the same group.

SDSI 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.
