Symbol Parameter Min Max Min Max Units FSCL Clock Frequency 100 400 kHz T1 (Note 1) Noise Suppression Time Constant at SCL, SDA Inputs 200 200 ns tAA SCL Low to SDA Data Out and ACK Out 3.5 1 ms tBUF (Note 1) Time the Bus must be Free Before a New Transmission Can Start 4.7 1.2 ms tHD; STA Start Condition Hold Time 4 0.6 ms tLOW Clock Low Period 4.7 1.2 ms tHIGH Clock High Period 4 0.6 ms tSU; STA Start Condition Setup Time (for a Repeated Start Condition) 4.7 0.6 ms tHD; DAT Data in Hold Time 0 0 ns tSU; DAT Data in Setup Time 50 50 ns tR (Note 1) SDA and SCL Rise Time 1 0.3 ms tF (Note 1) SDA and SCL Fall Time 300 300 ns tSU; STO Stop Condition Setup Time 4 0.6 ms tDH Data Out Hold Time 100 100 ns 1. This parameter is tested initially and after a design or process change that affects the parameter. Table 7. WRITE CYCLE LIMITS Symbol Parameter Min Typ Max Units tWR Write Cycle Time 10 ms * The write cycle time is the time from a valid stop condition of a write sequence to the end of the internal program/erase cycle. During the write cycle, the bus interface circuits are disabled, SDA is allowed to remain high, and the device does not respond to its slave address. Table 8.
