LPM4, this five kinds of low-power consumption situations are as follows：
LPM0：CPU is stopped, and MCLK clocks stop, and SMCLK, ACLK clock are also working.
LPM1：CPU is stopped, and MCLK clocks stop, if when activity pattern DCO is not used as MCLK and SMCLK
Zhong Shi, then DC generator be prohibited, be otherwise maintained for active state, SMCLK, ACLK clock are still also working.
LPM2：CPU is stopped, and MCLK, SMCLK clock are stopped, if DCO is not used as MCLK, SMCLK, from
The dynamic DC generator that is prohibited keeps effective, and ACLK is also in work.
LPM3：CPU is stopped, and MCLK, SMCLK clock are stopped, and DCO clocks are also stopped, only ACLK clocks
Also in working condition.
LPM4：CPU is stopped, and MCLK, SMCLK clock are stopped, and DCO clocks are also stopped, and ACLK also stops
Work, it is least in power-consuming at this time.
In the present embodiment, when the induction zone that 2030 chips of the MCP enter reader is swashed by the magnetic field that reader is sent out
When living, an interrupt signal is just generated, 430 microcontrollers of MSP exit LPM3 after receiving interrupt signal, and operating current is
2030 chip of 300uA, MCP enters standby mode, operating current 4uA；NRF9E5 chips are continually maintained under sleep state.
In the present embodiment, 430 microcontrollers of the MSP can judge whether the signal being currently received is high-frequency signal, if
It is no, then above-mentioned state is maintained, if so, 430 microcontrollers of MSP enter activity pattern (AM, ACTVE MODE), operating current is
300uA, MCP2030 chip enter working condition, operating current 13uA, and NRF9E5 enters reiving/transmitting state (TX/RX), corresponding
Operating current be 19/16mA.At this point, 430 microcontrollers of MSP can control NRF9E5 to be emitted and received work, thus with institute
State the interaction that reader carries out data and instruction.After the completion of SHF communication, entire electronic tag is slept into depth once more
Dormancy state.
In conclusion in the present embodiment, the dual-radio design that high frequency wakes up and hyperfrequency is received and dispatched is used, compares the electricity of single-frequency
The advantages of subtab has penetrability good, and signal is strong, good compatibility.In addition, only can just be called out when entering the read area of reader
Awake electronic tag enters working condition, is maintained at deep sleep under normal circumstances, therefore, can lower power consumption significantly, prolong
The working life of long electronic tag.
