蓝牙低能量(BLE)芯片上的系统--CMT4501
- 240-960MHz带编码器的单片OOK发射器--CMT2157B
- CMT2157B是一款真正意义上的单芯片、高灵活性、超低功耗、带编码器的 OOK射频发射芯片，非常适合于 240至 960 MHz的无线应用场合。该芯片可实现完全兼容市面上最常用的527、1527、2262和 2240等编码格式。此外，还支持用户各种自定义编码。该芯片支持 4个独立按键或多达 10个扫描按键，每个按键的键值可以单独配置，组合按键之间也无需二极管隔离。出厂时，芯片默认为 1527编码方式并工作在 433.92 MHz。用户还可以通过 CMOSTEK提供的可视化操作界面 RFPDK和烧录工具将定制化的参数固化到芯片内部的 EEPROM中，以实现差异化应用。
- I2C湿度和温度传感器--TH06C
- The TH06C I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low drift and hystere．
- 高速转换温度传感器--T06
- The T06 family of I2C temperature sensors features high conversion speed (143 μs typical),programmable over or under temperature interrupt, and interrupt polarity with 200 ms (typical) sampling time.The output works as a comparator, that is, the output pin will go high or low with each new temperature sample.
