STM32F401
The STM32F401 line is the entry level to the STM32 F4 series. It is designed for medical, industrial and consumer applications requiring balanced performance and power efficiency with a high level of integration of embedded memories and peripherals inside packages as small as 3 x 3 mm, in the most cost-effective way. The STM32F401 offers the performance of the
Cortex™-M4 core (with floating point unit) running at 84 MHz while reaching outstanding power figures in Run and Stop modes.
Performance: At 84 MHz, the STM32F401 delivers 105 DMIPS/285 CoreMark performance executing from Flash memory, with 0-wait states using ST’s ART Accelerator. The DSP instructions and the floating point unit enlarge the range of addressable applications.
Power efficiency: ST’s 90 nm process, ART Accelerator and the dynamic power scaling enables the current consumption in run mode and executing from Flash memory to be as low as 137 µA/MHz. In Stop mode, the power consumption can be as low as 11 µA typical.
Connectivity:
- Audio: dedicated audio PLL and 2 full duplex I²S
- Up to 11 communication interfaces (including 3x USARTs running at up to 10.5 Mbit/s, 4x SPI running at up to 42 Mbit/s, 3x I²C, SDIO)
- 1x USB 2.0 OTG full speed
- Analog: one 12-bit ADC reaching 2.4 MSPS
- Up to 10 timers: 16- and 32-bit running at up to 84 MHz
Integration: The STM32F401 portfolio provides from 128 to 256 Kbytes of Flash, 64 Kbytes of SRAM and from 49 to 100 pins in packages as small as 3 x 3 mm.
Cost effective DSP with FPU, ARM Cortex-M4 MCU with 128 Kbytes Flash, 84 MHz CPU, Art Accelerator
The STM32F401xB/STM32F401xC device family is based on the high-performance ARM®Cortex™-M4 32-bit RISC core operating at a frequency of up to 84 MHz. Its Cortex-M4 with FPU 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.
STM32F401xB/STM32F401xC devices incorporate high-speed embedded memories (Flash memory up to 256 Kbytes, up to 64 Kbytes of 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 one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers including one PWM timer for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces.
