2) Notification from ML7066
If ML7066 state settings cause a mismatch between an instruction and an internal status, a confirmation that is not listed in the
data sheet may be notified fairly infrequently. If you receive such a confirmation, simply discard it.
Example)
04_00 (Confirmation with Length=0)
04_02_02_02 (SET_TRX_STATE.request never has the data 02)
04_05_05_05_05_05_05 (SET_RSSI.indication never has Length=5)
3) Seal
The first and second generations are distinguished by the seal.
The seal of the second generation is ML7066B.
Note that the first generation includes the following restriction.
Restrictions: The timer value set in the SET_TIMER.request command should be 15 seconds or shorter.
4) Regulator
The regulator in ML7066 has a built-in overcurrent protection circuit. The current control is switched between the following
two levels, based on the supplied voltage. We have verified that the overcurrent protection circuit can prevent an occurred
inrush current from affecting the function and lifetime of ML7066. However, it cannot prevent an inrush current of the charge
in bypass capacitors or other parts at power-on alone. You should verify the protection on your implementation.
For a low VREG_OUT output voltage (VREG_IN*0.45V or lower): clamped at about 100mA.
For a high VREG_OUT output voltage (VREG_IN*0.45V or higher): clamped at about 500mA.
