125 DMIPS, EEMBC® CoreMark® performance up to 339 at 100 MHz

STMicroelectronics (ST) has announced that its STM32F410 microcontroller, a member of the STM32F4 Access Line, is now in volume production, supported by the new NUCLEO-F410RB development board. This opens the door to a smaller, lower-power, and lower-cost version of the high-performance STM32 F4 series.



The STM32F410 features an ARM® Cortex®-M4F core, delivering 125 DMIPS and an EEMBC® CoreMark® of 339 at 100 MHz. By leveraging ST's ART Accelerator™ and STM32's Dynamic Efficiency™ low-power technologies such as voltage scaling, dynamic power consumption can be reduced to 89 microamperes per megahertz (µA/MHz).

The quiescent current is only 6 microamps, making it suitable for a wide range of applications including wearables, Internet of Things products, sensor hubs, building automation, personal medical devices, and smartphones.

Supports Arduino Uno connection and ST morpho connector

The NUCLEO-F410RB is a new, economical STM32 Nucleo board designed to support the STM32F410. Its on-board Arduino Uno connectivity and ST morpho connectors allow for easy expansion with stackable modules such as motion sensing, Near-Field Communication (NFC), Bluetooth, and IEEE 802.15.4 wireless boards.

The latest STM32CubeF4 suite provides a complete ecosystem, including Hardware Abstraction Layer (HAL), middleware, example code, and the latest STM32CubeMX code generator.

The STM32F410 devices are designed for ultra-small package sizes and offer 64 to 128 kilobytes of Flash and 32 kilobytes of SRAM. It has a powerful peripheral set including motor control and up to six timers, including a 32-bit/100MHz timer.

Communication ports include SPI, I2C, I2S, USART, and ISO7816 interfaces, as well as a 12-bit DAC, which is not available in other STM32F41x devices. The STM32F410 is available in UFQFPN48 and LQFP64 packages, and when used in a 2.55mm x 2.58mm 36-bump WLCSP, it is the smallest device in the STM32F4 family.

For designers of sensing applications where high power consumption is a challenge, the STM32F410's support for Batch Acquisition Mode (BAM) will be a boon. This innovative Dynamic Efficiency technology from ST allows sensor data to be stored directly in SRAM while the CPU and Flash remain off, effectively leveraging the microcontroller's power management modes. The STM32F410 also introduces a new RUN mode that allows Flash to be powered down for optimal power savings.

The Nucleo-F410RB is priced at $14. Budgetary pricing for the STM32F410, based on annual orders of 10,000 pieces, is $1.40 for the WLCSP36 package with 64KB Flash and 32KB SRAM, and $1.856 for the LQFP64 package with 128KB Flash and 32KB SRAM.
