Figure 3 : I 2C interface timing definition Table 1 : Electric characteritics for I 2C interface (AC characteristics) Item Symbol Pin name Min Typ Max Unit I2CCK clock frequency Fi2cck I2CCK 400 kHz START condition hold time tHD,STA I2CCK I2CDT 0.6 s I2CCK clock Low period tLOW I2CCK 1.3 s I2CCK clock High period tHIGH I2CCK 0.6 s Setup time for repetition START condition tSU,STA I2CCK I2CDT 0.6 s Data hold time tHD,DAT I2CCK I2CDT 0 (*) 0.9 s Data setup time tSU,DAT I2CCK I2CDT 100 ns I2CDT, I2CCK rising time tr I2CCK I2CDT 300 ns I2CDT, I2CCK falling time tf I2CCK I2CDT 300 ns STOP condition setup time tSU,STO I2CCK I2CDT 0.6 s Bus free time between STOP and START tBUF I2CCK I2CDT 1.3 s * : Although the I2C specification defines a condition that 300 ns of hold time is required internally, LC898214XC is designed for a condition with typ. 20 ns of hold time. If I2CDT signal is unstable around falling point of I2CCK signal, please implement an appropriate treatment on board, such as inserting a resistor. |
