What are the key features of STM32L562CEU3?
- ARM Cortex-M33 core with TrustZone delivering 165 DMIPS for secure IoT and wearable applications
- Up to 512 KB flash and 256 KB SRAM supporting large firmware stacks with data buffers
- Hardware AES and Public Key Accelerator (PKA) for on-chip cryptographic operations without performance penalty
- Integrated SMPS regulator minimizing external power components and improving energy efficiency
- Ultra-low-power design enabling sub-µA standby current for long-life battery-powered products
What is STM32L562CEU3 used for?
STM32L562CEU3 targets IoT edge nodes, wearable medical devices, and smart home sensors where both ultra-low power consumption and hardware security are critical. Its TrustZone and hardware AES/PKA enable secure boot, encrypted firmware updates, and TLS session handling directly on-chip, eliminating external security elements. The integrated SMPS and multiple low-power modes allow battery-operated products to operate for months from a small Li-ion cell while maintaining a secure communication link.

Frequently Asked Questions
How does TrustZone in STM32L562CEU3 protect firmware in an IoT sensor node against physical attack?
STM32L562CEU3 implements ARM TrustZone-M, dividing the Cortex-M33 into secure and non-secure execution worlds. The secure world holds the cryptographic keys, AES engine, and PKA in isolated 256 KB of SRAM and 512 KB flash partitions, preventing non-secure application code from accessing these assets even if the RTOS or application layer is compromised. This architecture meets PSA Certified Level 2 security requirements for IoT devices.
What is the processing performance of STM32L562CEU3 and can it run an ML inference model for gesture recognition?
STM32L562CEU3 delivers 165 DMIPS at up to 110 MHz on its Cortex-M33 core with single-precision FPU. For gesture recognition using a small fully-connected neural network with 10k parameters, ST's X-CUBE-AI can compile and deploy the model into the 512 KB flash, achieving inference latency under 5 ms per frame — sufficient for real-time 200 Hz IMU sample processing in a wearable device.
How does the integrated SMPS in STM32L562CEU3 compare to using an external LDO regulator for a 1.8 V coin-cell powered design?
The on-chip SMPS in STM32L562CEU3 operates with efficiencies above 85% at 10 mA load, compared to roughly 60% efficiency for an LDO stepping from 3 V to 1.2 V at the same current. Over a 1000-hour operational life from a 230 mAh CR2032 coin cell at 1 mA average, the SMPS saves approximately 58 mAh, extending battery life by over 25% versus an LDO-only solution.
Which package does STM32L562CEU3 use and how does its footprint compare to the LQFP-48 variant?
STM32L562CEU3 comes in a QFN package measuring approximately 5 mm × 5 mm with 0.5 mm pitch, offering roughly 75% less board area than the LQFP-48 package at 9 mm × 9 mm. The QFN exposed pad also improves thermal conductivity to the PCB, reducing junction temperature by 5–10°C at 100 mA active current compared to the LQFP in the same application.
