Under normal operating conditions are divided into: Active mode The module is active; all functions are normally available for data transmission and reception; the module can switch to Idle mode or PSM mode in this mode. Idle The module is in a light sleep state, the module is in a network connection state and can accept paging messages. In this mode, the module can be switched to active mode or PSM mode. PSM Module only RTC work, the module is in the network is not connected, no longer accept paging messages. When DTE (Data Terminal Equipment) actively send data or timer T3412 (periodic update) timeout, the module will be awakened. 第 8 页 共 17 页 6.3 3 Powerr supply & powe er saving g techno ology The e NBXX-01 module's pow wer supply range is 3.1 V to 4.2 V, making sure e that the inp put voltage does not drop below 3.1V. If the supplyy voltage is lo ower than 3..1 V, the module will be abnormal. The e performancce of the module depe ends largely y on the pow wer supply, so the des sign of the pow wer supply module is verry importantt, in which th he power supply currentt of at least 0.5A. For better perfo ormance, it is recommended to place a 100u uF tantalum m capacitor and three cera amic capacittors 100nf, 100pf and 22 2pf near VB BAT. The refe erence circu uit is shown below。 Figure 3 Refe erence desig gn for powerr supply The e maximum consumption n of moduless under PSM M is 5uA.PS SM, the main n purpose is to reduce mod dule power consumption n and extend battery po ower supply time.

Whe en the modu ule is in the PSM mode, the network k activities will w be closed d, including the t search for the t cell messsage, the cell reelection, etc. But the T3412 timer will (associated witth periodic TAU U updates) continue to work. The ere are two ways for mod dules to quitt PSM mode e: one way iss DTE sendss the data ac ctively, the othe er is when th he T3412 tim mer goes out, the TAU starts, the mo odule exits P PSM.

The ese sequencce diagram is as followss: Fig gure 5 Turn off the pow wer supply sequence NBX XX-01 modu ule reset: the e module ca an reset to a low level of o reset pin ffor a certain time.
