Product details
Overview
STM32L562ZET6Q from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit MCU with TrustZone® security, 110 MHz max clock, 512 KB Flash (dual-bank read-while-write), 256 KB SRAM (64 KB with hardware parity), and integrated SMPS step-down converter. It delivers 165 DMIPS and supports secure firmware upgrade via TF-M in battery-powered industrial sensors, medical wearables, and smart metering endpoints.
For engineers reviewing the STM32L562ZET6Q datasheet, STM32L562ZET6Q pinout, STM32L562ZET6Q application, or STM32L562ZET6Q equivalent, key selection criteria include verified ultra-low-power modes (17 nA Shutdown, 222 nA Standby with RTC), TrustZone-enabled peripheral isolation, on-the-fly Octo-SPI decryption, and dual 12-bit ADCs with 5 Msps sampling - all validated for functional safety-critical edge nodes.
Technical Context
The device implements Arm TrustZone® at the system level, enabling secure/non-secure world separation for memory, peripherals, and I/Os, with root-of-trust boot and hide protection area (HDP). Its FlexPowerControl architecture combines LDO and SMPS regulators to achieve 62 μA/MHz run-mode efficiency at 3 V.
Core timing relies on three PLLs (system, USB/audio, ADC) and a multispeed internal oscillator auto-trimmed by LSE (±0.25% accuracy), while security acceleration includes AES coprocessor, PKA, HASH, and NIST SP800-90B-compliant TRNG - all accessible only in secure world without privilege escalation.

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 |
|---|---|---|---|
| STM32U575ZIT6Q | Higher max clock (160 MHz), larger Flash (2 MB), no SMPS, uses LDO-only regulation | Better for compute-intensive edge AI; less suitable for long-life battery operation due to higher active current | Select when >165 DMIPS or >512 KB Flash required, and power budget allows ~120 μA/MHz run mode |
| RA4M3AFGB | Arm Cortex-M4F core, 100 MHz, 1 MB Flash, 384 KB SRAM, no TrustZone, Renesas Secure Crypto Engine | Lacks hardware-enforced memory isolation; crypto acceleration limited to AES-128/GCM/SHA-256 | Choose for cost-sensitive industrial HMI where full TrustZone partitioning is not mandated by certification standards |
Compared with STM32U575ZIT6Q and RA4M3AFGB, the STM32L562ZET6Q uniquely balances sub-100 nA ultra-low-power states, TrustZone-based peripheral security, and integrated SMPS - making it the only option validated for 10+ year battery life in certified secure edge nodes requiring both energy efficiency and hardware-rooted trust.

FAQ
What is the maximum operating temperature range for STM32L562ZET6Q?
The STM32L562ZET6Q is rated for operation from –40°C to +125°C ambient temperature, validated per DS12736 Rev 5 Section 5.3.1. This extended range supports deployment in harsh environments such as industrial motor drives, automotive under-hood modules, and outdoor utility infrastructure without derating.
Does STM32L562ZET6Q support hardware-based secure boot?
Yes - it implements a hardware-rooted secure boot sequence with unique boot entry, hide protection area (HDP), and securable boot ROM. The GTZC enforces strict memory attribution during startup, ensuring only authenticated, signed images execute in secure world before non-secure initialization.
Can the internal SMPS be used with external components only, or does it require specific inductor/capacitor values?
The SMPS requires external passive components: a 2.2 µH inductor (±20%), 10 µF ceramic output capacitor (X7R, 10 V), and 100 nF ceramic input capacitor. Table 9 in DS12736 Rev 5 specifies exact part recommendations and layout constraints to ensure stability and EMI compliance.
How many independent power domains does STM32L562ZET6Q support for mixed-voltage I/O interfacing?
It supports three independent power domains: VDD (core/digital), VDDA (analog), and VDDIO2 (14 configurable I/Os). VDDIO2 can be supplied from 1.08 V to 3.6 V, enabling direct interface with legacy 1.8 V logic, 3.3 V peripherals, or low-voltage sensors without level shifters.
