New microcontroller with full-speed USB On-The-Go (OTG) interface
ST Microelectronics has added another new line to its STM32 MCU family. This new ARM Cortex M3 based MCUs STM32F105 and STM32F107, features full-speed USB On-The-Go (OTG) interface, which allows end products to act as a USB Host or USB Device.
The other features are,
1. Ethernet interface with hardware support for IEEE1588 Precision Time Protocol (PTP).
2. This family includes two CAN2.0B controllers
3. These new MCUs support simultaneous operation of Ethernet, USB OTG and CAN2.0B peripherals, thereby allowing developers to build gateway devices using a combination of these interfaces in a single chip.
4. Offers advanced Phase-Locked Loop scheme, enabling audio-class I2S communications. So that the STM32 can read, decode and output audio from external storage such as a USB mass-storage device or MP3 player.
5. Human-Machine-Interface (HMI) functions such as Play and Stop buttons, and display interfacing, can be hosted on this MCU. This will allow use in various home-audio products, such as docking systems, alarm-clock/music players and home theatre.
"This new MCU family brings the benefits of the STM32 architecture to extra applications in the industrial, medical, building automation, home audio, and domestic appliance markets," said Jim Nicholas, General Manager of ST's Microcontroller Division. "There are now 75 MCUs across all STM32 families, benefiting from the 32-bit ARM Cortex-M3 processor and complete pin-to-pin and software compatibility, enabling our customers to base a complete line of products on a single MCU platform."
The suggested applications include, 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.
