Note:
1. The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state)
for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tI2DVKH symbolizes I
2C timing
(I2) with respect to the time data input signals (D) reach the valid state (V) relative to the tI2C clock reference (K) going to the
high (H) state or setup time. Also, tI2SXKL symbolizes I
2C timing (I2) for the time that the data with respect to the start condition
(S) went invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH symbolizes I
2C
timing (I2) for the time that the data with respect to the stop condition (P) reaching the valid state (V) relative to the tI2C clock
reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used with the appropriate
letter: R (rise) or F (fall).
2. As a transmitter, the MPC8535E provides a delay time of at least 300 ns for the SDA signal (referred to the Vihmin of the SCL
signal) to bridge the undefined region of the falling edge of SCL to avoid unintended generation of Start or Stop condition.
When the MPC8535E acts as the I2C bus master while transmitting, the MPC8535E drives both SCL and SDA. As long as the
load on SCL and SDA are balanced, the MPC8535E would not cause unintended generation of Start or Stop condition.
Therefore, the 300 ns SDA output delay time is not a concern. For details of the I2C frequency calculation, refer to
Determining
the I2C Frequency Divider Ratio for SCL (AN2919). Note that the I2C Source Clock Frequency is half of the CCB clock
frequency for the MPC8535E.MPC8535E
3. The maximum tI2DVKH has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal.
4. CB = capacitance of one bus line in pF.
