INTRODUCTION
The ARM® Cortex™-M4-based STM32 F4 series is an extension of the industry-leading STM32 portfolio towards even higher performance. Like the STM32 F2 series, these MCUs leverage ST‘s 90 nm NVM technology and ST’s ART Accelerator™ to reach the industry’s highest benchmark scores for Cortex-M-based microncontrollers with 210 DMIPS at 168 MHz operating frequency, 363 Coremark score.
The DSP instructions and the FPU (floating point unit) enlarge the range of addressable applications.
The STM32 F4 series is the result of a perfect symbiose of the real-time control capabilities of an MCU and the signal processing performance of a DSP, and thus complements the STM32 portfolio with a new class of devices, digital signal controllers (DSC).
The STM32 F4 series remains pin-to-pin and software compatible with the STM32 F2 series and features more SRAM, peripheral improvements such as full duplex I˛S, improved RTC and faster ADCs.
Prices beginning from $5.74 for the STM32F407VET6 with 512 Kbytes of Flash and 192 Kbytes RAM in the LQFP100 package, for orders of more than 1000 units.

The STM32 F4 series remains pin-to-pin and software compatible with the STM32 F2 series and features more SRAM, peripheral improvements such as full duplex I˛S, improved RTC and faster ADCs.
- Ultra-fast data transfers, with a 7-layer multi-AHB bus matrix and multi-DMA controllers, which allow concurrent execution and data transfers
- The integrated single-precision FPU boosts the execution of control algorithms, adds more features to applications, improves code efficiency, reduces time-to-market, eliminates scaling and saturation, and allows the use of meta-language tools
- High integration, with up to 1 Mbyte of on-chip Flash memory, 192 Kbytes of SRAM, 4K SRAM battery back-up, 512 bytes of OTP memory make it store critical user data such as Ethernet MAC addresses or Cryptographic Key, reset circuit, internal RCs, PLLs, sub 1microAmp real-time clock with sub-second accuracy.
- Extra
flexibility to reduce power consumption in applications requiring both
high processing power and low-power performance when running at low
voltage or on rechargeable batteries.
These include 4 Kbytes of backup SRAM to save data in standby or battery backup modes, a typical RTC consumption of <1uA in Vbat mode, and an internal voltage regulator with power scaling capability, allowing the selection of performance or lower consumption - An outstanding tool and software ecosystem with a broad offering of Integrated Development Environments, Meta-language tools, a DSP library, inexpensive starter kits, software libraries and stacks
