STM32F405xx, STM32F407xx Description
2 Description
The STM32F405xx and STM32F407xx family is based on the high-performance ARM
®
Cortex
®
-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4
core features a Floating point unit (FPU) single precision which supports all 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 application security.
The STM32F405xx and STM32F407xx family incorporates high-speed embedded
memories (Flash memory up to 1 Mbyte, up to 192
Kbytes of SRAM), up to 4 Kbytes of
backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two
APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve 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.

Ss full duplex. To achieve 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 two UARTs
• An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the
ULPI),
• Two CANs
• An SDIO/MMC interface
• Ethernet and the camera interface available on STM32F407xx devices only.
New advanced peripherals include an SDIO, an enhanced flexible static memory control
(FSMC) interface (for devices offered in packages of 100 pins and more), a camera
interface for CMOS sensors. Refer to
Table 2: STM32F405xx and STM32F407xx: features
and peripheral counts for the list of peripherals available on each part number.
The STM32F405xx and STM32F407xx family operates in the –40 to +105 °C temperature
range from a 1.8 to 3.6
V power supply. The supply voltage can drop to 1.7 V when the
device operates in the 0 to 70
°C temperature range using an external power supply
supervisor: refer to
Section : Internal reset OFF. A comprehensive set of power-saving
mode allows the design of low-power applications.
The STM32F405xx and STM32F407xx family offers devices in various packages ranging
from 64 pins to 176 pins. The set of included peripherals changes with the device chosen.
These features make the STM32F405xx and STM32F407xx microcontroller family suitable
for a wide range of applications:
• Motor drive and application control
• Medical equipment
• Industrial applications: PLC, inverters, circuit breakers
• Printers, and scanners
• Alarm systems, video intercom, and HVAC
• Home audio appliances
