Product details
Overview
STM32L562RET6P from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit microcontroller with TrustZone® security, 512 KB Flash, 256 KB SRAM, and integrated SMPS step-down converter. It delivers 165 DMIPS at up to 110 MHz, supports AES+PKA cryptographic acceleration, and operates from 1.71 V to 3.6 V across –40°C to +125°C. It is deployed in battery-powered industrial sensors requiring secure firmware updates and sub-μA standby operation.
For engineers reviewing the STM32L562RET6P datasheet, STM32L562RET6P pinout, STM32L562RET6P application, or STM32L562RET6P equivalent, key selection criteria include TrustZone-enabled secure boot, 222 nA Standby mode with RTC, dual-bank read-while-write Flash, octo-SPI on-the-fly decryption, and 114 GPIOs with independent supply down to 1.08 V.
Technical Context
The STM32L562RET6P implements a dual-core security architecture via Arm TrustZone®, partitioning memory and peripherals into secure/non-secure worlds with hardware-enforced isolation. Its ART Accelerator includes an 8-KB instruction cache enabling zero-wait-state execution from Flash at 110 MHz.
Power management integrates both LDO and SMPS regulators, supporting dynamic voltage scaling and three configurable output ranges. Low-power modes include Shutdown (17 nA), Standby with RTC (222 nA), and Stop 2 with RTC (3.16 µA), all featuring 5 wakeup pins and 5 µs wake-up latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power secure MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32U575RIT6 | Higher max frequency (160 MHz), larger Flash (2 MB), no SMPS, higher active current (110 µA/MHz) | Better suited for compute-intensive edge AI workloads; lacks integrated SMPS for battery optimization | Select when raw performance outweighs battery life; verify thermal design for sustained 160 MHz operation |
| RA4M3GJ32FHB | Arm Cortex-M4F core, 1 MB Flash, 384 KB SRAM, no TrustZone, Renesas Secure Crypto Engine instead of PKA/AES | Strong real-time determinism and motor control peripherals; limited cryptographic acceleration compared to STM32L562 | Prefer for deterministic motor control + BLE coexistence; avoid if PSA Level 3 or FIPS 140-2 compliance is required |
Compared with STM32U575RIT6, the STM32L562RET6P offers superior energy efficiency and integrated SMPS for long-life battery systems, while RA4M3GJ32FHB provides stronger real-time peripherals but weaker hardware security primitives and no on-the-fly external memory decryption.

FAQ
What is the maximum operating temperature for STM32L562RET6P?
The STM32L562RET6P is qualified for industrial temperature range: –40°C to +125°C ambient. This rating applies to the LQFP48 package variant and is validated per JEDEC JESD22-A108. Thermal derating begins above 105°C for sustained operation; junction temperature must remain below 150°C under all conditions.
Does STM32L562RET6P support USB Type-C Power Delivery?
Yes - it integrates a dedicated UCPD (USB Type-C™ and Power Delivery) controller compliant with USB PD 3.0 specification. The peripheral supports programmable power rules, VCONN switching, and secure authentication via embedded RSS, enabling certified USB-C sink/source/port controller functionality without external PD PHY.
How many GPIOs support independent I/O supply (VDDIO)?
Up to 14 GPIOs support independent VDDIO supply down to 1.08 V, enabling direct interfacing with low-voltage peripherals (e.g., 1.2 V or 1.8 V sensors, memories, or transceivers) while the core runs at 3.3 V. These pins are distributed across GPIO ports A, B, C, D, E, F, G, H, and I as defined in Section 4.2 of DS12736 Rev 5.
Is the 96-bit unique ID accessible to non-secure firmware?
No - the 96-bit unique ID is only readable from the secure world via TZ-aware instructions (e.g., secure SVC calls). Non-secure firmware receives a masked or hashed version unless explicitly exposed through a secure service API. This behavior is enforced by the Global TrustZone Controller (GTZC) and verified in the device's RDP Level 2 configuration.
