Low-power MCUs

8 April 2015 DSP, Micros & Memory

STMicroelectronics has combined its ultra low-power microcontroller (MCU) technology with ARM know-how to create the STM32L4 series for energy-conscious consumer, industrial, medical and metering applications. The first two devices in the series – STM32L476 and STM32L486 – feature an 80 MHz ARM Cortex-M4 core with DSP and floating-point unit (FPU). With the added advantage of the ST ART Accelerator, which allows zero-wait execution from Flash, the devices achieve up to 100 DMIPS at just 100 μA/MHz active power consumption. Up to 1 MB of dual-bank Flash supports sophisticated applications and read-while-write capability, in addition to 128 KB of SRAM.
