Introduction

ST50L integrates ARM Coretex®-M4 (32-bit RISC core operating at a 48MHz frequency) MCU with LoRa modulation.  It offers an ultra-long-range spectrum communication and high interference immunity simultaneously minimizing power consumption.

The ST50L can achieve sensitivity under -136 dBm.  It has high sensitivity and combined with the integrated +21 dBm power amplifier yields.  The industry-leading link makes it optimal for any low data rate application.  LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques.  Solving traditional issues between range, interference immunity, and power consumption.

Technical Support

AcSiP has a stronger support chain in technical service which included FAE, HW, SW, PE resource involved.

1)HW

  • SiP Module

Those Tabpages of ‘Specification’, ‘HDK’ could be refered to know this product further well.

  • Validation & Certification

AcSiP has accumulated lots of experience in wireless communication and provide solution of RF design and protocol survey to help clients’ products meet local regulation and join global ecosystem well.  From project deveoping to product getting certification approval, even know-how in deployment stage, we has collected useful data here for user reference. 

               


2)SW

We have developed low band module to support CN470, EU433 regional clients for another LoRaWAN ecosystem and smart meter industry.  

        AcSiP provide kinds of software for ST50X series product,ST50H/ST50HE/AI50H/ST50L,to develop IoT relevant applications.

         There are main LoRa examples within SDK show behind.

  • LoRaWAN_AT_Slave
  • LoRaWAN_End_Node
  • SubGHz_Phy_PingPong

3)Training & E-Service

    FAE is first layer to handle all technical events or service demand.  Clients and customers could ask help via familiar channel or sales host to get positive response efficiency or check out online E-Service window finding the relevant resource as well.  AcSiP has prepared those data for products in technical support or training courses.

General Description

The ST50L integrates ARM Coretex®-M4 (32-bit RISC core operating at a frequency of up to 48MHz) MCU and LoRa/FSK modulation that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

The ST50L can achieve a sensitivity of over -136 dBm.  The high sensitivity combined with the integrated +21 dBm power amplifier yields industry leading link budget making it optimal for any low data rate application requiring range or robustness.  LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.

Part Number Frequency Range Spreading Factor Bandwidth Effective Bitrate Est. Sensitivity

Pin Layout Definition

 

RF Layout Guide

    Application note have showed essential RF layout info for developer reference and make certification approval easier.

    Whether a harmonic suppression circuit is needed, depends on the EMI test result.

    The Default LPF value are L5=15nH Murata LQW15AN, C1=7pF, C2=7pF.

    The enhanced LPF value are L5=15nH Murata LQW15AN, L6=8.2nH Murata LQG15HS,

    L7=3.9nH Murata LQG15HS, C1=3.6pF, C2=3.3pF.


Engineer Service

    AcSiP provide HW/SW relevant engineer service for clients in module design phase and its technical resource has shown on each individual tabpage also.  Additionally, we have provided those design review serivce before the engineer sample came out even debugged for revised one and the client can ask our sales window, E-Service for this help.

  • Schematic review
  • Layout review in RF matching、PCB antenna simulation
