22 / 28 page 22 FN8209.1 January 3, 2006 A.C. CHARACTERISTICS (See Figure 22, Figure 23, Figure 24) A.C. TEST CONDITIONS NONVOLATILE WRITE CYCLE TIMING CAPACITANCE (TA = 25°C, F = 1.0 MHZ, VCC = 5V) Notes: 1. Typical values are for TA = 25°C and VCC = 5.0V Notes: 2. Cb = total capacitance of one bus line in pF. Notes: 3. Over recommended operating conditions, unless otherwise specified Notes: 4. tWC is the time from a valid STOP condition at the end of a write sequence to the end of the self-timed internal nonvolatile write cycle. It is the minimum cycle time to be allowed for any nonvolatile write by the user, unless Acknowledge Polling is used. Notes: 5. This parameter is not 100% tested.
