Professional China Radio - STM32F730R8T6 IC MCU 32BIT 64KB FLASH 64LQFP – Ronghua

Description

The STM32F730x8 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 STM32F730x8 devices incorporate high-speed embedded memories with a Flash
memory of 64 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 multiAHB 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 generalpurpose 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 or with the integrated HS PHY depending on the part number)
• 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.
The STM32F730x8 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. A
comprehensive set of power-saving mode allows the design of low-power applications.
The STM32F730x8 devices offer devices in 4 packages ranging from 64 pins to 176 pins.
The set of included peripherals changes with the device chosen.
