Notes: (1) The device enters the Active state after any start, and remains active: for 9 clock cycles if the Device Select Bits in the Slave Address

Byte are incorrect or until 200nS after a stop ending a read or write operation.

that initiates a nonvolatile write cycle; or 9 clock cycles after any start that is not followed by the correct Device Select Bits in the Slave

Address Byte.

(4) For reference only and not tested.

(13)Threshold voltages based on the higher of Vcc or Vback.

(14)Using recommended crystal and oscillator network applied to X1 and X2 (25°C).

Notes: (1) This parameter is not 100% tested.

(2) The input capacitance between x1 and x2 pins can be varied between 5pF and 19.75pF by using analog trimming registers
