28 / 38 page ![]() DC and AC parameters M24C08-W M24C08-R M24C08-F 28/38 DocID023924 Rev 4 Table 17. 100 kHz AC characteristics (I2C Standard mode)(1) 1. Values recommended by the I2C bus Standard-mode specification for a robust design of the I2C bus application. Note that the M24xxx devices decode correctly faster timings as specified in Table 16: 400 kHz AC characteristics. Symbol Alt. Parameter Min. Max. Unit fC fSCL Clock frequency - 100 kHz tCHCL tHIGH Clock pulse width high 4 - µs tCLCH tLOW Clock pulse width low 4.7 - µs tXH1XH2 tR Input signal rise time - 1 µs tXL1XL2 tF Input signal fall time - 300 ns tQL1QL2(2) 2. Characterized only. tF SDA fall time - 300 ns tDXCH tSU:DAT Data in setup time 250 - ns tCLDX tHD:DAT Data in hold time 0 - ns tCLQX(3) 3. To avoid spurious Start and Stop conditions, a minimum delay is placed between SCL=1 and the falling or rising edge of SDA. tDH Data out hold time 200 - ns tCLQV(4) 4. tCLQV is the time (from the falling edge of SCL) required by the SDA bus line to reach either 0.3 VCC or 0.7 VCC, assuming that Rbus × Cbus time constant is within the values specified in Figure 12. tAA Clock low to next data valid (access time) - 3450 ns tCHDL(5) 5. For a reStart condition, or following a Write cycle. tSU:STA Start condition setup time 4.7 - µs tDLCL tHD:STA Start condition hold time 4 - µs tCHDH tSU:STO Stop condition setup time 4 - µs tDHDL tBUF Time between Stop condition and next Start condition 4.7 - µs tW tWR Write time - 5 ms tNS(2) Pulse width ignored (input filter on SCL and SDA), single glitch - 100 ns |
