91 / 144 page  i.MX25 Applications Processor for Consumer and Industrial Products, Rev. 3 Freescale Semiconductor 91 3.7.11 Inter IC Communication (I2C) Timing The I2C communication protocol consists of the following seven elements: •Start • Data source/recipient • Data direction • Slave acknowledge •Data • Data acknowledge • Stop Figure 64 shows the timing of the I2C module. Table 67 and Table 68 describe the I2C module timing parameters (IC1–IC6) shown in the figure. Figure 64. I2C Module Timing Diagram Table 67. I2C Module Timing Parameters: 3.0 V +/–0.30 V ID Parameter Standard Mode Fast Mode Unit Min. Max. Min. Max. IC1 I2CLK cycle time 10 - 2.5 μs IC2 Hold time (repeated) START condition 4.0 - 0.6 - μs IC3 Set-up time for STOP condition 4.0 - 0.6 - μs IC4 Data hold time 01 1 A device must internally provide a hold time of at least 300 ns for I2DAT signal in order to bridge the undefined region of the falling edge of I2CLK. 3.452 01 0.92 μs IC5 HIGH Period of I2CLK Clock 4.0 - 0.6 - μs IC6 LOW Period of the I2CLK Clock 4.7 - 1.3 - μs IC7 Set-up time for a repeated START condition 4.7 - 0.6 - μs IC8 Data set-up time 250 - 1003 -ns IC9 Bus free time between a STOP and START condition 4.7 - 1.3 - μs IC10 Rise time of both I2DAT and I2CLK signals - 1000 20+0.1Cb 4 300 ns IC11 Fall time of both I2DAT and I2CLK signals - 300 20+0.1Cb 4 300 ns IC12 Capacitive load for each bus line (Cb) - 400 - 400 pF IC10 IC11 IC9 IC2 IC8 IC4 IC7 IC3 IC6 IC10 IC5 IC11 START STOP START START I2DAT I2CLK IC1 |
