8.14.5.4 I²C

The CC3220MODx and CC3220MODAx MCUs include one I2C module operating with standard (100 kbps) or fast (400 kbps) transmission speeds.

Figure 8-13 shows the I²C timing diagram.

Figure 8-13 I²C Timing Diagram

Table 8-11 lists the I²C timing parameters.

Table 8-11 I²C Timing Parameters⁽³⁾

ITEM	NAME	DESCRIPTION	MIN	MAX	UNIT
T2	t_LP	Clock low period	See ⁽¹⁾		System clock
T3	t_SRT	SCL/SDA rise time		See ⁽²⁾	ns
T4	t_DH	Data hold time	NA
T5	t_SFT	SCL/SDA fall time	3		ns
T6	t_HT	Clock high time	See ⁽¹⁾		System clock
T7	t_DS	Data setup time	tLP/2		System clock
T8	t_SCSR	Start condition setup time	36		System clock
T9	t_SCS	Stop condition setup time	24		System clock

(1) This value depends on the value programmed in the clock period register of I²C. Maximum output frequency is the result of the minimal value programmed in this register.

(2) Because I²C is an open-drain interface, the controller can drive logic 0 only. Logic is the result of external pullup. Rise time depends on the value of the external signal capacitance and external pullup register.

(3) All timing is with 6-mA drive and 20-pF load.
