LPWAN Wireless Communication SoC

ASR6601 is a low-power WAN wireless communication SoC supporting LoRa. It integrates a general-purpose microcontroller and RF unit on a single chip, including an RF transceiver, a modem and a 48 MHz basic frequency and 32-bit MCU with ARM STAR architecture. Multiple memory options include up to 256KB Flash and 64KB SRAM. The embedded LCD driver is built in, and AES, DES, RSA, ECC, SHA, SM2/3/4 hardware encryption is supported. The minimum size of QFN48 is only 6mm x 6mm. With the SoC design, ASR6601 is currently the best LPWAN chip supporting LoRa in the market featuring low power consumption, high performance, and low cost. It can be widely used in smart city, smart home, smart metering, wisdom fire, smart agriculture, wearable devices, etc.
