Dynamic Efficiency Microcontrollers

STMicroThe STM32F401 Dynamic Efficiency microcontrollers extend battery life and support innovative new features in mobile phones, tablets, and smart watches. They help manage MEMS sensors in smart-connected devices and are well suited for Internet-of-Things (IoT) applications and fieldbus-powered industrial equipment.

The STM32F401 microcontrollers include an ART accelerator, a prefetch queue, and a branch cache. This enables zero-wait-state execution from flash, which boosts performance to 105 DMIPS (285 CoreMark) at 84 MHz. The microcontrollers’ 90-nm process technology boosts performance and reduces dynamic power. Its dynamic voltage scaling optimizes the operating voltage to meet performance demands and minimize leakage.

The STM32F401 microcontrollers integrate up to 512 KB of flash and 96 KB SRAM in a 3.06-mm × 3.06-mm chip-scale package and feature a 9-µA at 1.8 V Stop mode current. The devices’ peripherals include three 1-Mbps I2C ports, three USARTs, four SPI ports, two full-duplex I2S audio interfaces, a USB 2.0 OTG full-speed interface, an SDIO interface, 12-bit 2.4-MSPS 16-channel ADC, and up to 10 timers.

Pricing for the STM32F401 microcontrollers starts at $2.88 in 10,000-unit quantities.
