STM32L4P5VGT6 - Ultra-Low-Power Cortex-M4 MCU | STMicroelectronics
MPN: STM32L4P5VGT6 ✓ Hoạt độngSTM32L4P5VGT6 Tóm tắt
What is an ARM Cortex-M4 microcontroller? It is a 32-bit processor core designed for embedded systems, featuring a single-cycle multiply-accumulate (MAC) unit, hardware divide, and optional single-precision floating-point unit (FPU). The Cortex-M4 is part of the ARM Cortex-M family, which includes the M0, M0+, M3, M4, and M7 cores, each optimized for different performance and power trade-offs. In the system hierarchy, a microcontroller (MCU) integrates the processor core, memory, and peripherals on a single chip, serving as the central processing unit in embedded systems such as IoT devices, industrial controllers, and consumer electronics.
Key features include a rich set of analog peripherals: two 12-bit DACs, three 12-bit ADCs with hardware oversampling, two operational amplifiers, two comparators, and an internal voltage reference buffer. The device also integrates advanced digital peripherals: two CAN FD controllers, one USB 2.0 OTG FS/HS, one SDMMC interface, and a flexible memory controller (FMC) for external memory expansion. The STM32L4P5VGT6 supports multiple low-power modes, including Sleep, Low-power Run, Low-power Sleep, Stop 0/1/2, and Standby, with a typical current consumption of 100 nA in Standby mode with backup domain.
The STM32L4P5VGT6 is built on ST's ultra-low-power technology, featuring a dynamic voltage scaling (DVS) capability that adjusts the core voltage to optimize power consumption at different operating frequencies. The device includes a hardware cryptographic accelerator (AES, DES, 3DES) and a true random number generator (TRNG), enhancing security for connected applications. The rich set of timers includes two advanced-control timers, six general-purpose timers, two basic timers, and two low-power timers, providing precise timing and PWM generation.
Typical applications include IoT nodes, smart meters, portable medical devices, industrial sensors, and wearable devices. The ultra-low-power modes and high integration make it ideal for battery-powered systems requiring long operational life. The device also supports a wide operating temperature range of -40°C to +85°C, suitable for industrial environments.
When designing with this MCU, pay attention to the power supply decoupling: place a 100 nF capacitor close to each VDD pin and a 4.7 uF capacitor at the main power input. For low-power operation, configure the GPIOs to analog mode when unused to reduce leakage current. The STM32L4P5VGT6 is supported by STM32CubeMX and STM32CubeL4 firmware package, simplifying development.

Ghi chú thiết kế
For low-power operation, configure unused GPIOs to analog mode to reduce leakage current. Use the low-power modes (Stop 2, Standby) to minimize consumption. Ensure the backup domain is properly powered with VBAT for RTC and backup registers. According to ST application note AN4621, using the internal LDO or external SMPS (on 'P' variants) can optimize power efficiency.
Place a 100 nF decoupling capacitor close to each VDD pin and a 4.7 uF capacitor at the main power input. For the VDDA pin, use a dedicated analog supply with a ferrite bead to reduce noise. Ensure a solid ground plane for the LQFP package's exposed pad (if present) to improve thermal performance.
Do not exceed the absolute maximum ratings for supply voltage (3.6V). Ensure the boot pins (BOOT0) are configured correctly for your application. When using the 'P' variant, if VDD12 pins are not used, leave them unconnected to avoid short circuits. Verify the crystal oscillator layout for OSC_IN/OSC_OUT to prevent startup issues.
