79 / 92 page  MB90800 Series DS07-13733-6E 79 (8) I2C timing (AVCC = VCC = 3.3 V ± 0.3 V, VSS = AVSS = 0.0 V, TA = − 40 °C to + 85 °C) *1 : fCP is internal operation clock frequency. Refer to “ (1) Clock timing”. *2 : R, C : Pull-up resistor and load capacitor of the SCL and SDA lines. *3 : The maximum tHDDAT only has to be met if the device does not stretch the “L” width (tLOW) of the SCL signal. *4 : Refer to “ • Note of SDA and SCL set-up time”. Parameter Symbol Conditions Standard- mode Unit Min Max SCL clock frequency fSCL When power supply voltage of external pull-up resistor is 5.0 V R = 1.0 kΩ, C = 50 pF*2 When power supply voltage of external pull-up resistor is 3.6 V R = 1.0 kΩ, C = 50 pF*2 0100 kHz Hold time (repeated) START condition SDA ↓ → SCL ↓ tHDSTA 4.0 ⎯μs “L” width of the SCL clock tLOW 4.7 ⎯μs “H” width of the SCL clock tHIGH 4.0 ⎯μs Set-up time for a repeated START condition SCL ↑ → SDA ↓ tSUSTA 4.7 ⎯μs Data hold time SCL ↓ → SDA ↓ ↑ tHDDAT 0 3.45 *3 μs Data set-up time SDA ↓ ↑ → SCL ↑ tSUDAT When power supply voltage of external pull-up resistor is 5.0 V fCP*1 ≤ 20 MHz, R = 1.0 kΩ, C = 50 pF*2 When power supply voltage of external pull-up resistor is 3.6 V fCP*1 ≤ 20 MHz, R = 1.0 kΩ, C = 50 pF*2 250 *4 ⎯ ns When power supply voltage of external pull-up resistor is 5.0 V fCP*1 > 20 MHz, R = 1.0 kΩ, C = 50 pF*2 When power supply voltage of external pull-up resistor is 3.6 V fCP*1 > 20 MHz, R = 1.0 kΩ, C = 50 pF*2 200 *4 ⎯ ns Set-up time for STOP condition SCL ↑ → SDA ↑ tSUSTO When power supply voltage of external pull-up resistor is 5.0 V R = 1.0 kΩ, C = 50 pF*2 When power supply voltage of external pull-up resistor is 3.6 V R = 1.0 kΩ, C = 50 pF*2 4.0 ⎯μs Bus free time between a STOP and START condition tBUS 4.7 ⎯μs |
