DIGITAL CHARACTERISTICS (T

A = 25° C; VL = 2.4V - 3.6V; GND=0V)

SWITCHING CHARACTERISTICS- CONTROL PORT- TWO-WIRE FORMAT

(Note 7) (TA =25° C; VL = 2.4 V - 5.0 V; Inputs: Logic 0 = GND, Logic 1 = VL, CL =30 pF)

Note:

7. The Two-Wire Format is compatible with the I2C protocol.

8. Data must be held for sufficient time to bridge the transition time, tfc, of SCL.

9. The acknowledge delay is based on MCLK and can limit the maximum transaction speed.

10.

for Single-Speed Mode and

for Double-Speed Mode.
