Low-power MCUs

9 June 2010 DSP, Micros & Memory

STMicroelectronics’s STM32L series encompasses a range of ARM Cortex-M3 microcontrollers as part of ST’s EnergyLite platform of ultra low-power products. The devices include flexible brown-out reset; onboard Flash with error correction code (ECC) support; a memory protection unit (MPU) and JTAG fuse. They also integrate USB 2.0 Full Speed support and embedded LCD drivers. Integrated support for direct memory access (DMA) allows peripherals to remain active, allowing developers to realise savings by turning off the Flash and the CPU while the application is running. The MCUs boast no less than six low-power operating modes. The integrated analog features are capable of operating at supply voltages down to 1,8 V, while the digital functions are able to operate from a supply voltage as low as 1,65 V, allowing prolonged operation in battery-powered equipment as the battery voltage decays.
