Datasheet

- production data

Features

Includes ST state-of-the-art patented

technology

Core

• 32-bit Arm® Cortex®-M7 core with double-

precision FPU and L1 cache: 16 Kbytes of data

and 16 Kbytes of instruction cache; frequency

up to 480 MHz, MPU, 1027 DMIPS/

2.14 DMIPS/MHz (Dhrystone 2.1), and DSP

instructions

Memories

• Up to 2 Mbytes of flash memory with read-

while-write support

• Up to 1 Mbyte of RAM: 192 Kbytes of TCM

RAM (inc. 64 Kbytes of ITCM RAM +

128 Kbytes of DTCM RAM for time critical

routines), Up to 864 Kbytes of user SRAM, and

4 Kbytes of SRAM in Backup domain

• Dual mode Quad-SPI memory interface

running up to 133 MHz

• Flexible external memory controller with up to

32-bit data bus: SRAM, PSRAM,

SDRAM/LPSDR SDRAM, NOR/NAND flash

memory clocked up to 100 MHz in

Synchronous mode

• CRC calculation unit

Security

• ROP, PC-ROP, active tamper

General-purpose input/outputs

• Up to 168 I/O ports with interrupt capability

Reset and power management

• 3 separate power domains which can be

independently clock-gated or switched off:

– D1: high-performance capabilities

– D2: communication peripherals and timers

– D3: reset/clock control/power management

• 1.62 to 3.6 V application supply and I/Os

• POR, PDR, PVD and BOR

• Dedicated USB power embedding a 3.3 V

internal regulator to supply the internal PHYs

• Embedded regulator (LDO) with configurable

scalable output to supply the digital circuitry

• Voltage scaling in Run and Stop mode (6

configurable ranges)

• Backup regulator (~0.9 V)

• Voltage reference for analog peripheral/VREF+

• Low-power modes: Sleep, Stop, Standby and

VBAT supporting battery charging

Low-power consumption

• VBAT battery operating mode with charging

capability

• CPU and domain power state monitoring pins

• 2.95 µA in Standby mode (Backup SRAM OFF,

RTC/LSE ON)

Clock management

• Internal oscillators: 64 MHz HSI, 48 MHz

HSI48, 4 MHz CSI, 32 kHz LSI

• External oscillators: 4-48 MHz HSE,

32.768 kHz LSE
