STM32L4P5CGU6P Overview

STM32L4P5CGU6P is a series of ultra-low-power microcontroller devices (part of the STM32L4+ series) using the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at frequencies up to 120 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU) that supports all Arm® single-precision data processing instructions and all data types. The Cortex-M4 core also implements a full set of DSP (digital signal processing) instructions and a Memory Protection Unit (MPU) for enhanced application security. The STM32L4P5CGU6P embeds high-speed memory (up to 1mbyte of Flash memory and 320kbytes of SRAM), Flexible External Memory Controller (FSMC) for static memory (for devices with packages of 100 pins or above), two OCTOSPI Flash memory interfaces (with devices in packages of 100 pins or above) and a wide range of enhanced I/O and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. The STM32L4P5CGU6P embeds several protection mechanisms for embedded flash and SRAM: read protection, write protection, proprietary code read protection and firewall. The STM32L4P5CGT6 provides two fast 12-bit ADCs (5 Msps), two comparators, two op amps, two DAC channels, an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timers, two A 16-bit PWM timer dedicated to motor control, seven general-purpose 16-bit timers, and two 16-bit low-power timers. The device supports two digital filters for external sigma delta modulators (DFSDMs). Additionally, up to 24 capacitive sensing channels are available.
