STM32 launches the super value model

STM released the product details of a new ultra-low price 32-bit microcontroller on March 31, 2010. The new product extends the advantages of STM32's advanced industrial standard kernel to the market of low-performance equipment applications, providing developers with more choices and no longer restricted by the proprietary processor architecture.

So far, in order to upgrade the original 16 bit design and obtain higher performance and application flexibility, designers have to choose high-end microcontrollers designed for more complex applications. In order to improve this situation, STM32 super value microcontroller is introduced by STM32, which integrates 24MHz arm Cortex-M3 processor core and peripheral features optimized for 16 bit applications, such as home entertainment equipment, home appliances and industrial equipment. Under the condition of 24 MHz clock and zero wait state flash memory access, the performance of STM32 super value type reaches 30 DMIPS, which exceeds most 16 bit processors. The industrial standard processor price of the new series of products is less than US $1 (subject to mass shipment), but it has more advantages, and developers can obtain a lot of development knowledge and tools.

The features of STM32 super value series application centered products include 12 16 bit timers, one of which is PWM timer for motor control. Up to 26 timer channels and up to 100 pins in the package. The series also provides a 12 bit high-speed analog-to-digital converter (ADC) to meet various industrial control requirements. Italian French semiconductor also provides free software support services, including a complete set of 3-phase motor control software library for home appliances and motor control, as well as a free VDE certification software library to help home appliances meet the mandatory standard of en / IEC60335-1 class B.

STM32 super value series products also have built-in hardware circuit supporting CEC (consumer electronic control) protocol, simplifying the application of CEC in TV, Blu ray player, personal video recorder and home theater equipment. CEC protocol is HDMI standard. Through CEC protocol, up to 10 HDMI devices can identify and communicate with each other, and handle convenient use and operation functions. For example, one controller controls multiple devices with one key. The hardware implementation of CEC protocol can also reduce the load of the processor, enable it to handle more advanced functions, and further improve the product value.



In addition, STM32 super value series products also integrate a 12 digit analog-to-digital converter (DAC). Developers can add audio support functions in various applications, such as security equipment or home automation system, to meet the market opportunities of analog waveform generation control.



STM32 super value series will allow more developers to enter STM32 microcontroller family of STM32. At present, STM32 includes five product lines to provide customers with price sensitive, power sensitive, interconnect centric or high-performance microcontrollers. STM32 series products have 110 products, providing various functional features and on-chip storage capacity. At the same time, all products are compatible with each other in software and pins. This commonality can simplify the choice of strategic processor platform, help equipment manufacturers to expand and upgrade design, reuse the same intellectual property rights and development tools in different designs, and minimize product cost and time to market.



At present, STM32 super value series microcontrollers are providing test samples to key customers. Mass production began in March 2010.
