RF receiving IC demodulates the information received from the outside world and supplies it to the MCU for judgment execution.The CMT2210LH is an all-in-one receiver with a digital-analog hybrid Page4 design. The product's 26MHz crystal provides the PLL's reference frequency and digital clock, supports OOK demodulation output with data rate of 1.0-5.0Ksps, and supports time-configurable periodic reset to avoid crashes caused by various external causes. The CMT2210LH supports two voltage range operating scenarios, which can be used in 5V system applications or as a 3V system application. The chip uses LNA + MIXER + IFFILTER + limiter and PLL's low-IF architecture to achieve wireless reception at frequencies below 1G. The analog front end is responsible for downmixing the RF signal to the intermediate frequency, and converting the real-time RSSI into an 8-bit digital signal through the SAR-ADC, and sending it to the internal OOK demodulation and related processing. At the same time, the internal circuit mixes the intermediate frequency signal to zero frequency (baseband) and performs a series of filtering and judging processing. At the same time, the AGC dynamic control analog front end is performed, and finally the original signal is demodulated and output to the off-chip through the data pin.

slave mode communication systems, 433MHz products can actually be used.In this way, the master-slave topology has the advantages of simple network structure, easy layout, and short power-on time. This is actually the prototype of the early smart home. 433MHz, 470MHz is now widely used in the smart meter reading industry.

Meander Line Antenna The length of the meander line antenna is difficult to predict. It is usually a bit longer than a quarter wave but dependent on its exact geometry and proximity to the ground plane. Note:

In Figure 3 the ground plane is shown in black. S is the distance from the ground plane. See Figure 5 for approximate dimensions. This type of antenna is always a PCB version. The antenna is printed on the top layer and a ground plane is placed near the antenna on the top layer. There must be no ground plane underneath the radiating section of the antenna. The real part of the impedance of this antenna is about 15-25W, depending on geometry and proximity to the ground plane. The impedance matching is done by adjusting the length of the antenna until the input impedance is at the unity conductance circle (when normalised to 50W), in the top half of the Smith chart

(Point A). A shunt capacitor is then connected between the antenna input and ground to match to 50W

(Point B). Experimental measurement is used to determine the correct design. Page6 Real Designs CSR recommends keeping metal objects as far away from the antenna as possible. Keeping metallic objects out of the near field is usually adequate. Dielectric materials (like plastic or FR-4) detune an antenna by lowering its resonant frequency. The effect is not as serious as placing an antenna next to metal objects and can be corrected by reducing the length of the antenna. Therefore it is important for the antenna to be tuned when it is in the product. This is done during the development of the product. 2.4 MCU The STM32F051x family incorporates the high-performance ARM Cortex-M0 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (Flash memory up to 64 Kbytes and SRAM up to 8 Kbytes), and an extensive range of enhanced peripherals and I/Os.

Minimum and maximum values Unless otherwise specified, the minimum and maximum values are guaranteed in the worst conditions of ambient temperature, supply voltage and frequencies by tests in production on 100% of the devices with an ambient temperature at TA = 25 C and TA = TAmax (given by the selected temperature range). Data based on characterization results, design simulation and/or technology characteristics are indicated in the table footnotes and are not tested in production. Based on characterization, the minimum and maximum values refer to sample tests and represent the mean value plus or minus three times the standard deviation (mean3). Typical values Unless otherwise specified, typical data are based on TA = 25 C, VDD = VDDA = 3.3 V. They are given only as design guidelines and are not tested. Typical ADC accuracy values are determined by characterization of a batch of samples from a standard diffusion lot over the full temperature range, where 95% of the devices have an error less than or equal to the value indicated (mean2). Typical curves Unless otherwise specified, all typical curves are given only as design guidelines and are not tested.
