CHAPTER 4 THE STM32F407ZGT6 MICROCONTROLLER
4. Introduction to the chapter
In this chapter is located the information about the heart of STM32-P407 – its microcontroller. The
information is a modified version of the datasheet provided by its manufacturers.
4.1 The microcontroller
•Core: ARM 32-bit Cortex™-M4 CPU with FPU, Adaptive real-time accelerator (ART
Accelerator™) allowing 0-wait state execution from Flash memory, frequency up to 168 MHz,
memory protection unit, 210 DMIPS/1.25 DMIPS/MHz (Dhrystone 2.1), and DSP instructions
•Memories
•1 Mbyte of Flash memory
•192+4 Kbytes of SRAM including 64-Kbyte of CCM (core coupled memory) data RAM
•Flexible static memory controller supporting Compact Flash, SRAM, PSRAM, NOR and
NAND memories
•LCD parallel interface, 8080/6800 modes
•Clock, reset and supply management
•1.8 V to 3.6 V application supply and I/Os
•POR, PDR, PVD and BOR
•4-to-26 MHz crystal oscillator
•Internal 16 MHz factory-trimmed RC (1% accuracy)
•32 kHz oscillator for RTC with calibration
•Internal 32 kHz RC with calibration
•Sleep, Stop and Standby modes
•VBATsupply for RTC, 20×32 bit backup registers + optional 4 KB backup SRAM
•3×12-bit, 2.4 MSPS A/D converters: 24 channels and 7.2 MSPS in triple interleaved mode
•2×12-bit D/A converters
•General-purpose DMA: 16-stream DMA controller with FIFOs and burst support
•Up to 17 timers: up to twelve 16-bit and two 32-bit timers up to 168 MHz, each with up to 4
IC/OC/PWM or pulse counter and quadrature (incremental) encoder input
•Debug mode
•Serial wire debug (SWD) & JTAG interfaces
•Cortex-M4 Embedded Trace Macrocell™
•Up to 114 I/O ports with interrupt capability
•Up to 15 communication interfaces
•3 × I2C interfaces (SMBus/PMBus)
•4 USARTs/2 UARTs (10.5 Mbit/s, ISO 7816 interface, LIN, IrDA, modem control)
•3 SPIs (37.5 Mbits/s), 2 with muxed full-duplex I2S to achieve audio class accuracy via
internal audio PLL or external clock
