概要
Description
STM32L562RET6 is STMicroelectronics’ ultra‑low‑power 32‑bit MCU in the STM32L5 family. It combines a Cortex‑M33 core (Armv8‑M) with TrustZone‑M security, a floating‑point unit, and DSP instructions, running up to about 110 MHz. It offers substantial on‑chip Flash and RAM and a broad peripheral set for battery‑powered apps: USB Full‑Speed, CAN, UART/SPI/I2C, multiple timers, ADCs, comparators, op‑amps, RTC, and cryptographic accelerators with hardware RNG. The device emphasizes energy efficiency with multiple low‑power modes and advanced power management, ideal for wearables, medical, and industrial sensors. It also supports secure boot and code isolation via TrustZone for firmware and data protection. The RET6 package is a 64‑pin LQFP. Development is supported by ST’s STM32CubeMX/IDE toolchain, HAL/LL drivers, and secure software libraries.
