Wireless transmission output power up to 20dBm (1.2Kbps, 433M)
Data transmission rate: 0.123-256kbps
Modulation mode: FSK, GFSK, and OOK
Power supply: 1.8-3.6 V
Ultra-low power consumption: 10nA (4.21ms) in power-off mode, 300nA in standby mode and 600nA (1.21ms) in sleep mode; The receiving current is 18.5mA, and the transmitting current can reach 80mA (200us)
Digital received signal strength indication (RSSI)
Timed wake-up function, wireless wake-up function (WUT)
Antenna automatic matching and two-way switch control
Configurable packet structure
Pre-synchronization signal detection
64-byte transceiver data register (FIFO)
Low battery power detection is integrated into the chip
On-chip temperature sensor and 8-bit analog-to-digital converter
Working temperature range: - 40~+80 ° C (temperature characteristics and product consistency are much better!)
voltage regulator
Frequency hopping function
Power-on reset function
Built-in crystal error adjustment function
The chip automatically calculates and checks CRC-16, and supports three 16-bit CRC polynomials
Frame headers of up to 4 bytes are available. Frame header filters are used at the receiving end, so that reception by address can be set.
