STMicroelectronics (ST), the world's leading semiconductor supplier across multiple electronic applications, announced the latest STM32F030 value series microcontroller. With a minimum order price of only $0.32, the STM32F030 is an ideal choice for low-budget projects. It also gives designers the opportunity to use a full-featured, 32-bit microcontroller-compatible product portfolio to increase application performance and expand product lines. The new STM32F030 value series is based on the 48MHz ARM Cortex-M0 processor core. Unlike competing products, the STM32F030 is only available at the price of an 8-bit microcontroller, but its performance and features are not affected. For example, if the core speed is not reduced, the STM32F030 also maintains a rich variety of peripherals.
Michel Buffa, general manager of STMicroelectronics' microcontroller products division, said: “The STM32F0 value-for-life makes 32-bit microcontrollers more accessible, especially for cost-sensitive applications. Engineers can use enhanced hardware performance to simplify software design and enable efficient innovation. In addition, the ARM developer community and ecosystem inspire developers to move from 8-bit development to the STM32 premium series."
Simplifying product selection and product differentiation positioning is the core of ST's new premium value concept. From the 16KB flash memory, 4KB RAM and 20-pin package low-end products, to 64KB flash memory, 8KB RAM, and high-level products in 32-, 48- or 64-pin packages, the STM32F030 product line has a total of 5 products, all with 12-bit 1Msample/ s analog-to-digital converters, 1.2V internal voltage reference circuits, communications peripherals, temperature sensors, and timers. The timer supports ADC synchronization, dead-time management, and motor control pulse width modulation (PWM) timing functions. In addition to the 48MHz core frequency, these rich peripherals make the STM32F030 value series stand out from other brands of 32-bit entry-level microcontrollers. The STM32F030's internal real-time clock and 5-channel direct memory access controller (DMA) are features not available in the same price range microcontroller. These two important features help to simplify application development and improve performance.
In addition, developers will also have access to ST's powerful portfolio of ARM Cortex-M microcontrollers. The STM32 product lineup includes more than 360 models of Cortex-M0, M3 and M4 micro-pins, software and peripherals compatible with each other. Controller products.
STMicroelectronics has now received orders for STM32F030 premium series and plans to mass production in the third quarter of 2013.
Coreless Motor product introduction:
Coreless Motor, small size, light weight (cylinder) - radial rotation/weeks to rotation (flat) - low noise, low power consumption, strong sense of vibration - simple structure - reliability - response time short Micro Vibration Motor is mainly used in mobile phones, toys, adult health supplies, etc
Function: fast speed, suitable for aircraft model, electric toothbrush,USB fan and other products.
Characteristic: the volume is 6MM 7MM fast.
Features: small size, fast speed, dc high speed motor starting voltage 0.6v is not possible for other motors.Wear shaking head, strong vibration feeling.
Operating temperature range:
Coreless Motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a Coreless Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Coreless Motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of Coreless Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry. Welcome to our factory.
