125kHz Low Frequency Wake-Up Receiver
UM2020 is a high-performance，3 channels ASK receiver
chip with ultra-low power consumption, which can detect the data of LF carrier
frequency in the range of 30khz~300khz and trigger the wake-up signal. The
three independent channels inside can be configured into different wake-up
modes. Each channel has RSSI detection function, the digitized RSSI value can
be read through SPI or I2C interface. The chip is used in PKE products, active-RFID
and other fields.
