the digital received signal strength indicator (RSSI)
timed wake-up function, wireless wake-up function (WUT)
the antenna automatically match and two-way switch control
configurable packet structure
preamble detection
 64-byte transmit and receive data register (FIFO)
on-chip integrated low battery detection
on-chip temperature sensor and 8-bit analog to digital converter
the working temperature range: -40 ~ + 80°C (temperature characteristics and product consistency is much better!)
The integrated voltage regulator
 frequency hopping
power-on reset function built-in crystal error adjustment function
the chip automatically calculate and check CRC-16, and supports three 16-bit CRC polynomial
 up to 4-byte frame header is available, the receiver using frame head filter, so you can set up to receive press address
