ASR6505 LoRa Wireless Communication Chipset Datasheet
■The ASR6505 is a general LoRa Wireless Communication Chipset, with integrated LoRa Radio Transceiver, LoRa Modem and an 8-Bit CISC MCU. The MCU uses an advanced STM 8-bit core, with 16MHz operation frequency. The LoRa Radio Transceiver has continuous frequency coverage from 150MHz to 960MHz. The LoRa Modem supports LoRa modulation for LPWAN use cases and (G)FSK modulation for legacy use cases. The LoRa Wireless Communication module designed by ASR6505 provides ultra long range and ultra low power communication for LPWAN application.
■The ASR6505 can achieve a high sensitivity of over -140dBm and the maximum transmit power is higher than +21dBm. This makes it suitable to be used in long range LPWAN and have high efficiency. The total chip package is of very small size, 8mm x 8mm, with totally 68 pins.
