*1

: Conditions ; fosc = 12.8 MHz, Ta = +25 °C, SW = “0” in locking state.

 

 

 

 

 

 

*2

: VCCIF = VCCRF = 3.0 V, fosc = 12.8 MHz, Ta = +25 °C, in power saving mode.

VIH = VCC, VIL = GND (at CLK, Data, LE)

 

 

 

 

 

 

*3

: AC coupling. 1000 pF capacitor is connected under the condition of Min operating frequency.

 

 

*4

: The symbol “–” (minus) means the direction of current flow.

: VCC = 3.0 V, Ta = +25 °C (I3 − I4) / [ (I3 + I4) / 2] ⋅ 100 (%)

 

 

 

 

 

 

*6

: VCC = 3.0 V, Ta = +25 °C [ (I2 − I1) / 2] / [ (I1 + I2) / 2] ⋅ 100 (%)

(Applied to both lDOL and lDOH)

 

*7

: VCC = 3.0 V, [IDO (+85 °C) − IDO (–40°C) / 2] / [IDO (+85 °C) + IDO (–40°C) / 2] ⋅ 100 (%) (Applied to both IDOL and IDOH)
