3.22 IIC Bus Interface

Table 3.22.1 IIC Bus Interface Signal Timing

Condition: VDDQ33 = 3.3 V ± 0.2 V [RZ/G2H, RZ/G2M V1.3, RZ/G2M V3.0, RZ/G2N] / ± 0.3 V [RZ/G2E] or

VDDQ18 = 1.8 V ± 0.1 V, GND = VSS = 0 V,

Tc = -40 to +115 °C [RZ/G2H, RZ/G2M V1.3], Ta = -40 to +85 °C [RZ/G2M V3.0, RZ/G2N, RZ/G2E],

Tj = -40 to +115 °C [RZ/G2M V3.0, RZ/G2N, RZ/G2E], CL = 30 pF

Notes. 1. All values are referenced at VDDQ*4 × 0.3 and VDDQ*4 × 0.7 levels.

2. To satisfy the I2C-bus specification, pull-up resistors (Rp) with the appropriate resistance must be included

depending on the total of bus capacitive load of each line.

Pull-up resistor range should be following, refer Table 3.21.2.

Rp(max) = tr /(0.8473*Cb)

Rp(min) = (VDDQ*4-VOL(max))/IOL

3. The total capacity (Cb) should be less than or equal to 100 pF.

4. VDDQ means VDDQ33 or VDDQ18
