STM32F732xx STM32F733xx

Description

The STM32F732xx and STM32F733xx devices are based on the high-performance ARM®

Cortex®-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex®-M7 core

features a single floating point unit (SFPU) precision which supports ARM® single-precision

data-processing instructions and data types. It also implements a full set of DSP instructions

and a memory protection unit (MPU) which enhances the application security.

The STM32F732xx and STM32F733xx devices incorporate high-speed embedded

memories with a Flash memory up to 512 Kbytes, 256 Kbytes of SRAM (including

64 Kbytes of data TCM RAM for critical real-time data), 16 Kbytes of instruction TCM RAM

(for critical real-time routines), 4 Kbytes of backup SRAM available in the lowest power

modes, and an extensive range of enhanced I/Os and peripherals connected to two APB

buses, two AHB buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnect

supporting internal and external memories access.

All the devices offer three 12-bit ADCs, two DACs, a low-power RTC, thirteen general-

purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-

bit timers, a true random number generator (RNG). They also feature standard and

advanced communication interfaces.

•

Up to three I2Cs

•

Five SPIs, three I2Ss in half duplex mode. To achieve the audio class accuracy, the I2S

peripherals can be clocked via a dedicated internal audio PLL or via an external clock

to allow synchronization.

•

Four USARTs plus four UARTs

•

An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the

ULPI in the STM32F732xx devices and with the integrated HS PHY in the

STM32F733xx devices)

•

One CAN

•

Two SAI serial audio interfaces

•

Two SDMMC host interfaces

Advanced peripherals include two SDMMC interfaces, a flexible memory control (FMC)

interface, a Quad-SPI Flash memory interface. Refer to Table 2: STM32F732xx and

STM32F733xx features and peripheral counts for the list of peripherals available on each

part number.

The STM32F732xx and STM32F733xx devices operate in the –40 to +105 °C temperature

range from a 1.7 to 3.6 V power supply. Dedicated supply inputs for the USB (OTG_FS and

OTG_HS) and the SDMMC2 (clock, command and 4-bit data) are available on all the

packages except LQFP100 and LQFP64 for a greater power supply choice.

The supply voltage can drop to 1.7 V with the use of an external power supply supervisor

(refer to Section 2.15.2: Internal reset OFF). A comprehensive set of power-saving mode

allows the design of low-power applications.

The STM32F732xx and STM32F733xx devices offer devices in 7 packages ranging from 64

pins to 176 pins. The set of included peripherals changes with the device chosen.
