HopeRF Micro-electronics CMT2210LC-ESR2

CMT2210LC is an ultra-low-power, high-performance, standalone OOK RF receiver designed for ISM band 315/433.92 MHz wireless applications. It is a true plug-and-play device requiring no register configuration or manual tuning — by selecting either a 19.7008 MHz or 27.1383 MHz crystal, the chip operates at 315 or 433.92 MHz. The device supports data rates from 1 to 5 kbps, making it ideal for pairing with encoder-based or MCU-based low-end transmitters. It operates reliably across a supply voltage range of 1.8 to 3.6 V. At 315 MHz, the chip achieves -109 dBm sensitivity with only 3.3 mA current consumption; at 433.92 MHz, it achieves -109 dBm sensitivity with only 3.8 mA. The device is housed in an SOP8 package for simple, low-cost manufacturing. The CMT2210LC receiver paired with CMT211x transmitters enables ultra-low-cost RF applications.
