Introduction
ST50HE integrates ARM Cortex®-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 ST50HE can achieve a sensitivity under -136 dBm. It has high sensitivity and combined with the integrated +14 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
ST50HE integrates
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 sigfox support resource to service clients for another LPWAN ecosystem.
AcSiP provide kinds of software for ST50X series product,ST50H/ST50HE/AI50H/ST50L,to develop IoT relevant applications.
There are main LoRa examples within above SW packages show behind.
♦ Essential Configuration and Commands Set reference
♦ Essential Configuration and Commands Set reference
• LoRaWAN_AT_Slave
• LoRaWAN_AT_Slave_Peripheral
• 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 ST50HE integrates ARM Cortex®-M4 (32-bit RISC core operating at a 48MHz frequency) MCU with LoRa modulation that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
The ST50HE can achieve a sensitivity of over -136 dBm. The high sensitivity combined with the integrated +14 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 |
ST50HE | 863~930MHz | 5~12 | 7.8~500KHz | LoRa BR: 0.013~17.4 kb/s | -138 dBm |
Kb/s(G)FSK BR:0.6~300kb/s | @125kHz, SF12 |

Step Info:
EK-ST50 series PCB Connector Description
RF Layout Guide
Application note have showed essential RF layout info for developer reference and make certification approval easier.
►Harmonic suppression
Whether a harmonic suppression circuit is needed, depends on the EMI test result.
Default value is L102=8.2nH Murata LQW15AN, C125=3.3pF, C126=3.3pF.
►ESD Protection
If used in a harsh ESD environment, the following example is reference design for ESD Protection,
the recommended part is: Semtech@Rclamp2451z (1-Line, 24V)
