7.10.5.13 I3C

For more details about features and additional description information on the device Inter-Integrated Circuit, see the corresponding sections within Signal Descriptions, Signal Descriptions and Detailed Description.

Table 7-42, Table 7-43, Figure 7-69, Table 7-44, and Figure 7-70 assume testing over the recommended operating conditions and electrical characteristic conditions.

  1. This is approximately equal to tLOWmin + tDS_ODmin + trDA_ODtyp + tSU_Odmin.
  2. The Controller may use a shorter Low period if the Controller knows that this is safe, when SDA is already above VIH.
  3. Based on tSPIKE, rise and fall times, and interconnect.
  4. This maximum High period may be exceeded when the signals can be safely seen by Legacy I2C Devices, and/or in consideration of the interconnect (for example: a short Bus).
  5. On a Legacy Bus where I2C Devices need to see Start, the tCAS Min value is further constrained.
  6. Targets that do not support the optional ENTASx CCCs shall use the tCAS Max value shown for ENTAS3.
  7. On a Mixed Bus with Fm Legacy I2C Devices, tAVAL is 300ns shorter than the Fm Bus Free Condition time (tBUF).

  1. FSCL = 1 / (tDIG_L + tDIG_H)
  2. tDIG_L and tDIG_H are the clock Low and High periods as seen at the receiver end of the I3C Bus using VIL and VIH.
  3. When communicating with an I3C Device on a mixed Bus, the tDIG_H_MIXED period must be constrained to make sure that I2C Devices do not interpret I3C signaling as valid I2C signaling.
  4. As both edges are used, the hold time needs to be satisfied for the respective edges; tCF + 3 for falling edge clocks, and tCR + 3 for rising edge clocks.
  5. Clock Frequency Minimum 0.01 MHz, Maximum 12.5 MHz
