2. Electrical Characteristics

Note:

tIICcyc: RIIC internal reference clock (IIC) cycle

Note 1. The value within parentheses is applicable when the value of the ICMR3.NF[1:0] bits is 11b while the digital filter is enabled by

the setting ICFER.NFE = 1.

Note 2. Cb is the total capacitance of the bus lines.

RIIC Timing (2/2)

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,

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