1 Description
The STM32F722xx and STM32F723xx 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 STM32F722xx and STM32F723xx 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 I
2
Cs
Five SPIs, three I
2
Ss in half duplex mode. To achieve the audio class accuracy, the I
2
S
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 STM32F722xx devices and with the integrated HS PHY in the
STM32F723xx 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: STM32F722xx and
STM32F723xx features and peripheral counts for the list of peripherals available on each
part number.
The STM32F722xx and STM32F723xx 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 STM32F722xx and STM32F723xx devices offer devices in 7 packages ranging from 64
pins to 176 pins. The set of included peripherals changes with the device chosen.
