Low power ARM Cortex based STM32L MCUs with increased memory densities

STMicroelectronics expanded its family of STM32L Ultra-Low-Power ARM Cortex-M3 Microcontroller with new devices with memory densities of 256 and 384 Kbytes, thereby offering a Flash memory range from 32 up to 384 Kbytes for embedded systems designs.
ST says its STM32L microcontrollers are the industry's first ultra-low-power ARM Cortex-M3 MCUs available from a top-10 silicon supplier and offer 33 DMIPS performance at 32MHz (max). The 32-bit STM32 consists of more than 180 variants with pin, software and peripheral compatibility.

The STM32L employs its low-leakage 130nm semiconductor chip manufacturing process technology for these products to produce low power consuming MCUs. For touch-sensing applications, the STM32L is supported by the availability of ST's STMTouch capacitive-touch-sensing firmware library, which now supports more than 200 devices within ST's 8-bit STM8 and 32-bit STM32 families.

ST also announced its STM32L's USB drivers are ready for use in Continua Health Alliance certified applications. Full certification is expected by the end of Q1 2011. The success of the USB interface in medical applications has led to standardization and the development of a dedicated class of device called the Personal Healthcare Device Class (PHDC). This new class enables health-related devices, such as exercise watches, blood pressure monitors, thermometers, weighing scales and glucose meters, to connect to a host and ease the communication between individuals and their fitness coach, or patients and their doctor.


Availability: Volumes of 64 and 128-Kbyte memory densities MCUS by the end of March 2011. 32-Kbyte memories will follow in Q2 2011
