(Note 3) I2C TIMING CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Notes 3, 15) SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS fSCL SCL Clock Frequency l 0 400 kHz tHD(SDA) Hold Time (Repeated) START Condition l 0.6 μs tLOW LOW Period of the SCL Clock Pin l 1.3 μs tHIGH HIGH Period of the SCL Clock Pin l 0.6 μs tSU(STA) Set-Up Time for a Repeated START Condition l 0.6 μs tHD(DAT) Data Hold Time l 0 0.9 μs tSU(DAT) Data Set-Up Time l 100 ns tr Rise Time for Both SDA and SCL Signals (Note 14) l 20+0.1CB 300 ns tf Fall Time for Both SDA and SCL Signals (Note 14) l 20+0.1CB 300 ns tSU(STO) Set-Up Time for STOP Condition l 0.6 μs Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: All voltage values are with respect to GND. Note 3: VCC = 2.7V to 5.5V unless otherwise specified. VREF = REF+ – REF–, VREFCM = (REF+ + REF–)/2, FS = 0.5VREF/GAIN; VIN = IN+ – IN–, VINCM = (IN+ + IN–)/2. Note 4: Use internal conversion clock or external conversion clock source with fEOSC = 307.2kHz unless otherwise specified. Note 5: Guaranteed by design, not subject to test. Note 6: Integral nonlinearity is defined as the deviation of a code from a straight line passing through the actual endpoints of the transfer curve. The deviation is measured from the center of the quantization band. Note 7: 50Hz mode (internal oscillator) or fEOSC = 256kHz ±2% (external oscillator). Note 8: 60Hz mode (internal oscillator) or fEOSC = 307.2kHz ±2% (external oscillator). Note 9: Simultaneous 50Hz/60Hz mode (internal oscillator) or fEOSC = 280kHz ±2% (external oscillator). Note 10: The external oscillator is connected to the CA0/f0 pin. The external oscillator frequency, fEOSC, is expressed in kHz. Note 11: The converter uses the internal oscillator. Note 12: The output noise includes the contribution of the internal calibration operations. Note 13: Guaranteed by design and test correlation. Note 14: CB = capacitance of one bus line in pF. Note 15: All values refer to VIH(MIN) and VIL(MAX) levels. |
