Mingjiada Supply ST STM32L151VBH6 STM32 Ultra-Low-Power MCU, 32MHz 32-Bit Microcontroller MCU

In today’s world of embedded system design, where there is an ever-increasing demand for a balance between high performance and low power consumption, STMicroelectronics’ (ST) STM32L151VBH6 has become the ideal core for numerous battery-powered and portable devices thanks to its outstanding energy efficiency and extensive peripheral resources. As a specialist supplier of electronic components, Mingjiada Electronics provides a long-term and stable supply of the STM32L151VBH6, offering customers genuine, original products and a one-stop order fulfilment service.

I. Detailed Product Description of the STM32L151VBH6
The STM32L151VBH6 is an ultra-low-power 32-bit microcontroller from STMicroelectronics’ STM32 L1 series. Based on the ARM® Cortex®-M3 32-bit RISC core, it operates at a maximum frequency of 32 MHz and delivers a processing performance of up to 33.3 DMIPS. The STM32L151VBH6 integrates 128KB of Flash (with ECC error correction), 16KB of SRAM and 4KB of true EEPROM, providing ample storage space for applications. Housed in a compact UFBGA-100 (7×7mm) package with 83 I/O pins, it is well-suited for space-constrained portable device designs.
The STM32L151VBH6 belongs to the STM32 L1 series, which utilises ST’s proprietary ultra-low-leakage process technology and features innovative automatic dynamic voltage regulation and five low-power modes, offering unrivalled platform flexibility for a wide range of applications.
