High-performance Cortex™-M4 MCU

STM32 F4 series

Announcement highlights

The STM32 F4 series brings to the market the world’s highest performance Cortex™-M microcontrollers

168 MHz FCPU/210 DMIPS363 Coremark score

The STM32 F4 series extends the STM32 portfolio 250+ compatible devices already in production, including the F1 series, F2 series and ultra-low-power L1 series

The STM32 F4 series reinforces ST’s current leadership in Cortex-M microcontrollers, with 45% world market share by units in (2010 or cumulated 2007 to Q1/11) according to ARM reporting

What is Cortex-M4?

1

Outstanding power efficiency

ART Accelerator™ reducing the number of accesses to Flash Voltage scaling to optimize performance/power consumption

VDD min down to 1.7 V Low-power modes with backup SRAM and RTC support

Typical values in VBAT mode

230 μA/MHz, 38.6 mA at 168 MHz executing Coremark benchmark from Flash memory (with peripherals off), made possible with: ST’s 90 nm process

allowing the CPU core to run at only 1.2 V
