Description

Wireless Rf Transceiver Module 

• Ultra-low consumption in power-down mode is 10nA (4.21ms), in the standby mode, 300nA, sleep mode 600nA (1.21ms)
• Receive current is 18.5mA, maximum emission current of 80mA (200us).
• Digital received signal strength indication (RSSI)
• Timed wake-up function, wireless wake-up function (WUT)
• The antenna automatically match and the two-way switch control
• Configurable packet structure
• The front synchronization signal detector
• 64 bytes of data transceiver register (FIFO)
• Chip integrated low-battery detection
• The on-chip temperature sensor and 8-bit analog-to-digital converters
• Operating temperature range: -40 to 80 ° C (temperature characteristics and product consistency is much better!)
• The integrated regulator
• Frequency hopping function
• The power-on reset function
• Built-in crystal error adjustment function
• The chip automatically calculate and check CRC-16, and the support of three 16-bit CRC polynomial
