STM32F469BG(2016) 数据手册 ( 数据表 ) - STMicroelectronics

Description

   The STM32F469xx devices are based on the high-performance Arm®(a) Cortex®-M4 32-bit RISC core operating at a frequency of up to 180 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 STM32F469xx devices incorporate high-speed embedded memories (Flash memory up to 2 Mbytes, up to 384 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, two 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, and a true random number generator (RNG). They also feature standard and advanced communication interfaces:

• Up to three I2Cs

• Six SPIs, two I2Ss 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 four UARTs

• An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the

   ULPI)

• Two CANs

• One SAI serial audio interface

• An SDMMC host interface

• Ethernet and camera interface

• LCD-TFT display controller

• Chrom-ART Accelerator™

• DSI Host.
