User Manual

1 Introduction
1.1 The ASR6601 is a LoRa soc chip. The interior is implemented by core of Cortex
M4 with softeware core of Semtech' s LoRa transceiver SX1262 . The module
can achieve 868(for EU)/915Mhz frequency band communication. The module
implements the LoRa device with CLASS A,B,C protocol, DTU and various
private protocols. Class A,B,C protocol is nonstandard Lorawan protocol and is
only suitable for our gateway. The MCU inside the module is powerful, with
48Mhz master frequency and 16kbytes Sram,128k flash, making a big leap in
performance from the previous ASR6505. In order to reduce the cost of hardware,
the Open MCU scheme can be used directly inside by user without expand
MCU.
The module’s maximum receiving sensitivity is up to - 140dBm, maximum transmit
power up to 14dBm@868MHz(for EU) Band / 94dBuV/m@3m@915MHz Band.
1.2 Main feature：
⚫ Maximum reception sensitivity is up to -148dBbm

94dBuV/m@3m@915MHz Band.
⚫ Maximum transmission speed: 62.5kbps
⚫ Minimum dormant current: 2uA
⚫ Maximum master frequency: 48Mhz
⚫ 16kbytes Sram, 128k Flash
