STMicroelectronics — STM32L4P5 Microcontroller (MCU)

The STMicroelectronics STM32L4P5, part of the STM32L4+ family of low-power microcontrollers, enables system developers to restrict power consumption to new low levels while offering the high performance of an Arm^® Cortex^®-M4 core operating at 120MHz.

The STM32L4P5 MCU, which supports a comprehensive set of power-saving modes, is ideal for use in wearable devices and other applications which require sophisticated functions, instant responses and a long run-time on a battery power source.

The Cortex-M4 core in the STM32L4P5 MCU includes a single-precision floating-point unit which supports all the Arm single-precision data-processing instructions and data types. The Cortex-M4 core also implements a full set of DSP instructions, and a memory protection unit which enhances the application’s security.

High-speed memory provision includes up to 1Mbyte of Flash memory and 320kbytes of SRAM, plus a flexible external memory controller for static memories, and two OctoSPI Flash memory interfaces, in parts with at least 100 pins. The memory resources are backed by protection mechanisms: read-out protection, write protection, proprietary code read-out protection, and a firewall.

Standard and advanced communication interfaces in the STM32L4P5 MCU are:
