STMicroelectronics Introduces Revolutionary New Applications for its 32-bit MCU STM32 Connectivity Line

Embedded Technology 2009, PACIFICO YOKOHAMA November 18-20, 2009 ST Booth: B-11
Tokyo, November 17,2009 - STMicroelectronics (NYSE: STM), a leading supplier of microcontroller units (MCUs), will showcase "Internet radio" and "Standby MCU" demonstrations with evaluation boards that use its STM32 Connectivity Line of ARM Cortex-M3 core-based 32-bit MCUs at its booth at Embedded Technology 2009. The exhibition will be held at PACIFICO YOKOHAMA, Japan, from Wednesday, November 18, to Friday, November 20, 2009. Both demonstrations run on an operating system (OS) from eForce Co., Ltd., a developer and manufacturer of embedded software, using applications from ZIPS Corporation, a vendor of middleware (TCP/IP) and firmware.

With the Internet radio demonstration, visitors to the booth will be able to listen to actual Internet radio transmissions on the LAN-connected STM32F107 evaluation board. A liquid crystal display implemented on the board also enables the listener to check out information on the transmissions currently playing. Usually devices such as PCs or high-performance mobile devices are used for listening to Internet radio, but in this demonstration ST uses just the STM32F107 with its built-in memory to carry out high-speed streaming, proving the sophisticated capability of its product. This demonstration can be applied for applications such as AV amplifiers, digital photo frames and digital TV, as well as for optional functions on items such as toys.

Furthermore, in the standby MCU demonstration, using the STM32F107 mounted as a slave-MCU on to the periphery of the main system-on-chip (SoC), ST shows how to implement high-performance Ethernet functionality on low-power consumption, at just 10mW or less (when standby mode). In this demonstration, the LAN-connected PC 'master' controls the slave-MCU operation mode while illustrating energy consumption rates in real-time. In addition, this demonstration, which targets applications such as printers and projectors connected to Ethernet, shows that the STM32F107 can run not only as a slave-MCU but also as a master MCU.

Both demonstrations use eForce's Real Time Operation System (RTOS) uC3 and TCP/IP uNET3 middleware, and the application software developed by ZIPS Corporation. The leading embedded technology of both these companies enables software to be implemented in limited-capacity built-in ROM/RAM enabling a compact embedded system.

About the STM32 MCU Connectivity Line
The STM32 Connectivity Line is part of the STM32 product range and has an Ethernet interface featuring hardware support for IEEE 1588 Precision Time Protocol (PTP). Implementing the protocol in hardware reduces CPU overhead and enables faster response for real-time applications and when synchronizing networked devices. In addition, the STM32 Connectivity Line adds a Full-speed USB On-The-Go (OTG) interface, which allows end products to act as a USB Host or USB Device.

Furthermore, the combination of advanced, connectivity-orientated peripherals, standard STM32 peripherals including a PWM timer, and the high processing performance of the 32-bit ARM Cortex-M3 CPU also allow developers to consolidate multiple functions such as motor-control, user-interface control and connectivity features in equipment such as domestic appliances, building controls or industrial automation. Other applications will include systems requiring network accessibility, data-logging, or USB peripheral extension, such as patient monitors, point-of-sale terminals, vending machines, and safety or security systems.
