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.
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.
