STM32L1 vs. STM32L4 - Which Microcontroller Board is More Power-efficient?
Are you looking for a power-efficient microcontroller board that can handle your projects? It can be a bit confusing as there are numerous options available in the market. However, our team has compared the STM32L1 and STM32L4 boards to provide you with detailed information on which one is more power-efficient.
STM32L1
Power Consumption
The STM32L1 series is designed for ultra-low-power applications. It consumes as low as 0.37 μA of current in standby mode, making it ideal for battery-powered devices. Additionally, this microcontroller board features dynamic voltage scaling, which adjusts the voltage supply according to the device's needs. This feature ensures an optimal power supply, preventing the devices from consuming excess power.
Performance
The STM32L1 board is loaded with an ARM Cortex M3 core processor that can run up to 32 MHz. It also comes with 128 KB of flash memory and 10 KB of SRAM. However, it doesn't offer floating-point unit (FPU) support, which makes it unsuitable for applications that require high-precision calculations.
STM32L4
Power Consumption
The STM32L4 series is also designed for low-power applications. It features the Smart Architecture of STMicroelectronics, which provides efficient energy management. The STM32L4 board consumes as low as 0.18 μA in standby mode. This feature saves power, thereby allowing battery-powered devices to last longer.
Performance
The STM32L4 board is loaded with an ARM Cortex M4 core processor, providing faster performance than the STM32L1 board. It can run up to 80 MHz with FPU support, making it suitable for applications that require high-precision calculations. The STM32L4 board also provides up to 1 MB of flash memory and 320 KB of SRAM.
Conclusion
Both the STM32L1 and STM32L4 microcontroller boards are excellent for low-power applications. However, the STM32L4 board is more power-efficient than the STM32L1 board, providing lower standby currents. Additionally, the STM32L4 board provides FPU support, making it suitable for applications that require high-precision calculations.
We hope this comparison has provided you with useful information for selecting the appropriate microcontroller board based on your project's requirements.
