G-NiceRF’s New LoRa Spread Spectrum Modulation SOC Wireless Module LoRa-STM32WLE5 with Built-in ARM and Industrial Grade Crystal Oscillator
LoRa-STM32WLE5 is the latest SOC wireless module developed by NiceRF, The main chip of this module uses STM32WLE5 chip from ST. The module uses LoRa® modulation, has a built-in industrial-grade crystal oscillator, and is based on the high-performance Arm® Cortex®-m4 32-bit RISC core with an operating frequency of up to 48 MHz. This core implements a complete set of DSP instructions and an independent memory protection unit (MPU), providing 256KB flash memory and 64KB operational memory, thereby improving application security. This module is mainly used in ultra-long-range wireless and ultra-low-power radio applications, and can be widely used in security systems, smart agriculture, industrial manufacturing, smart homes and other places.
STM32WLE module MPU features:
Operating Temperature: -40°C to 105°C
Frequency range: 150MHz to 960MHz
256KB flash memory, 64KB SRAM
True Random Number Generator (RNG), hardware encryption AES 256-bit
Sector Protection against Readout and Write (PCROP),
Hardware Public Key Accelerator (KPA)
High-efficiency Embedded SMPS Buck Converter
SMPS to LDO Intelligent Switch
Low Power BOR Power-Down Reset
Ultra-Low Power POR/PDR
Programmable Voltage Detector
Ultra-small size, built-in ARM, industrial grade crystal oscillator
The SOC wireless module has a volume of 17*14 (unit mm) and an ultra-small stamp hole design to facilitate secondary development by users. Built-in Arm® Cortex®-m4 32-bit RISC core Arm, coupled with an industrial-grade crystal oscillator with a temperature of 40-85°C, it can be used in industrial-grade applications.
LoRaA spread spectrum modulation low power consumption long distance transmission
In terms of communication technology, LoRa-STM32WLE5 uses LoRa spread spectrum modulation technology, which has the characteristics of low power consumption and long-distance transmission, making the module perform well in ultra-long-range wireless communications. Its receiving sensitivity is as high as -141dBm@BW=125KHz, the transmitting power is adjustable, up to 22dBm, and the transmission distance can reach more than 5000 meters. In terms of power consumption, its sleep current is less than 2uA, and its receiving current is less than 10mA. It is suitable for scenarios with high requirements on battery life and energy efficiency. These features provide ample opportunities for applications in areas such as security systems, smart agriculture, and industrial manufacturing.
Security encryption, read/write protection.
It supports 256-bit hardware encryption, PCROP read/write protection, ensuring the security and integrity of the data.
Supports multiple interface types
Support for multiple interface types, including UART, SPI, I²C, GPIO, and ADC, enables it to meet the interface requirements of different application scenarios, providing excellent scalability and flexibility.
