10.12 Input pin characteristics for SCL

[1]

To minimize power consumption when in soft power-down mode, the limit is VDDD  0.4 V.

[2]

To minimize power consumption when in soft power-down mode, the limit is 0.4 V.

[3]

The PR533 has a slope control according to the I2C-bus specification for the Fast mode. The slope control is always present and not

dependent of the I2C-bus speed.

10.13 Input/output pin characteristics for SDA

[1]

To minimize power consumption when in soft power-down mode, the limit is VDDD  0.4 V.

[2]

To minimize power consumption when in soft power-down mode, the limit is 0.4 V.

[3]

The PR533 has a slope control according to the I2C-bus specification for the Fast mode. The slope control is always present and not

dependent of the I2C-bus speed.
