Features

Includes ST state-of-the-art patented

technology

Ultra-low-power with FlexPowerControl

• 1.71 V to 3.6 V power supply

• –40 °C to +85/125 °C temperature range

• Low-power background-autonomous mode

(LPBAM): autonomous peripherals with DMA,

functional down to Stop 2 mode

• VBAT mode: supply for RTC, 32 x 32-bit backup

registers and 2-Kbyte backup SRAM

• 90 nA Shutdown mode (23 wake-up pins)

• 200 nA Standby mode (23 wake-up pins)

• 370 nA Standby mode with RTC

• 1.4 μA Stop 3 mode with 16-Kbyte SRAM

• 2.2 µA Stop 3 mode with full SRAM

• 3.0 µA Stop 2 mode with 16-Kbyte SRAM

• 4.6 µA Stop 2 mode with full SRAM

• 16.3 μA/MHz Run mode @ 3.3 V

Core

• Arm® 32-bit Cortex®-M33 CPU with

TrustZone®, MPU, DSP, and FPU

ART Accelerator

• 8-Kbyte instruction cache allowing 0-wait-state

execution from flash and external memories:

up to 160 MHz, 240 DMIPS

• 4-Kbyte data cache for external memories

Power management

• Embedded regulator (LDO) and SMPS

step-down converter supporting switch

on-the-fly and voltage scaling

Benchmarks

read-while-write, and 100 kcycles

• 274-Kbyte SRAM including up to 64-Kbyte

SRAM with ECC ON

• 1 Octo-SPI memory interface

Security and cryptography

• PSA level 3 and SESIP level 3 certified

• Arm® TrustZone® and securable I/Os,

memories and peripherals

• Flexible life cycle scheme with RDP and

password protected debug

• Root of trust thanks to unique boot entry and

secure hide protection area (HDP)

• Secure firmware installation (SFI) thanks to

embedded root-secure services (RSS)

• Secure data storage with hardware-unique key

(HUK)

• Secure firmware upgrade support with TF-M

• 2 AES coprocessors including one with

DPA resistance

• Public key accelerator, DPA resistant

• On-the-fly decryption of Octo-SPI external

memories

• HASH hardware accelerator
