STMicroelectronics brought additional features to its portfolio of STM32F0 Value Line ARM Cortex-M0 MCUs. The devices now feature USB connectivity and larger Flash options to boost support for cost-sensitive consumer, smart energy, communication gateway and Internet of Things (IoT) applications.

The addition of six devices expands the entry-level 32bit STM32F0 Value Line to address the 8bit and 16bit applications. These extend developers' flexibility to use the same MCU architecture for a range of needs, and allow the customer to introduce new products to market quickly and efficiently. The new devices open access to the wider STM32 portfolio, with more than 600 part numbers leveraging the full spectrum of ARM Cortex-M cores and extensive development support.

The STM32F030CC and STM32F030RC Value Line devices feature 256KB program Flash in 48-pin or 64-pin LQFP packages. Moreover, USB 2.0 Full Speed interface is now available in four STM32F070 Value Line devices compliant with Battery Charger Detection (BCD v1.2) and Link Power Management (LPM), enabling optimum energy efficiency and longer battery life, detailed the company.

These latest additions augment the strong feature-set of the STM32F0 Value Line, giving designers access to built-in safety functionalities, precise internal oscillators, multiple clock sources, and a calendar real-time clock (RTC) with alarm and periodic wakeup from stop/standby. Further important features include a 5-channel DMA controller, internal voltage regulator, 12bit/1?s ADC, and versatile communication capabilities such as two I2C interfaces, six USARTs and two SPIs.

The STM32F0 Value Line MCUs are sampling and entering volume production throughout 1Q15. The STM32F070F6P6 with 32KB Flash and USB support in TSSOP20 package is priced from $0.57 for 10,000 units. The STM32F0 software and hardware ecosystem now supports these new entrants.

For just $10.32, the NUCLEO-F070RB allows a fast evaluation and gives a quick access to the developer community for making prototypes. It can be used with various application expansion boards now accessible on the market. The configuration of the device takes only few seconds with the STM32CubeMX configuration tool. STM32CubeMX can also generate initialisation C-code, and automatically download STM32CubeF0 embedded software. This embedded software provides a high portability level to other STM32s, but users can also choose the STM32F0 Standard Peripherals Library or the highly optimised STM32F0Snippets. All STM32F0 peripherals are covered, from simple RTC up to full USB stack with many classes.
