Features
Description
The STM32F777xx, STM32F778Ax and STM32F779xx 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 floating point unit (FPU) which supports Arm® double-precision
and 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 STM32F777xx, STM32F778Ax and STM32F779xx devices incorporate high-speed
embedded memories with a Flash memory up to 2 Mbytes, 512 Kbytes of SRAM (including
128 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, 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), and a cryptographic acceleration cell.
They also feature standard and advanced communication interfaces:
•
Up to four I2Cs
•
Six SPIs, three I2Ss in half-duplex mode. 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 four UARTs
•
An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the
ULPI)
•
Three CANs
•
Two SAI serial audio interfaces
•
Two SDMMC host interfaces
•
Ethernet and camera interfaces
•
LCD-TFT display controller
•
Chrom-ART Accelerator™
•
SPDIFRX interface
•
HDMI-CEC
Advanced peripherals include two SDMMC interfaces, a flexible memory control (FMC)
interface, a Quad-SPI Flash memory interface, a camera interface for CMOS sensors and a
cryptographic acceleration cell.
The STM32F777xx, STM32F778Ax and STM32F779xx devices operate in the –40 to
+105 °C temperature range from a 1.7 to 3.6 V power supply. Dedicated supply inputs for
USB (OTG_FS and OTG_HS) and SDMMC2 (clock, command and 4-bit data) are available
on all the packages except LQFP100 for a greater power supply choice.
The supply voltage can drop to 1.7 V with the use of an external power supply supervisor. A
comprehensive set of power-saving mode allows the design of low-power applications.
The STM32F777xx, STM32F778Ax and STM32F779xx devices offer devices in 11
packages ranging from 100 pins to 216 pins. The set of included peripherals changes with
the device chosen.
These features make the STM32F777xx, STM32F778Ax and STM32F779xx
microcontrollers suitable for a wide range of applications:
•
Motor drive and application control
•
Medical equipment
•
Industrial applications: PLC, inverters, circuit breakers
•

•
Alarm systems, video intercom, and HVAC
•
Home audio appliances
•
Mobile applications, Internet of Things
•
Wearable devices: smartwatches
