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.

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
