Microcontrollers offer 100DMIPS processing capability
1 min read
STMicroelectronics' latest family of microcontrollers is said to offer the best balance of dynamic power consumption and execution performance, while boosting feature integration.
Combining high energy efficiency and over 100DMIPS processing capability, the STM32F401 mcus extend battery life and support new features in mobiles, tablets and smart watches.
They are suitable for managing MEMS sensors in smart connected devices, as well as Internet of Things (IoT) applications and fieldbus powered industrial equipment.
Additional features include an ART Accelerator, a prefetch queue and branch cache. This allows zero wait state execution from flash which boosts performance to 105DMIPS at 84MHz and helps achieve RUN current down to 128µA/MHz.
In addition, ST says 90nm process technology boosts performance and reduces dynamic power, while dynamic voltage scaling optimises the operating voltage to meet performance demands and minimise leakage. STOP mode current is 9µA at 1.8V.
Peripherals include three 1Mbit/s I2C ports, three USARTs, four SPI ports, two full duplex I2S audio interfaces, USB2.0 OTG Full-Speed interface, SDIO interface, 12bit 2.4MS/s 16channel a/d converter, and up to 10 timers.
