Microchip Technology’s BodyCom™ Technology

Microchip Technology has announced the introduction of BodyCom™ Technology which makes use of the human body as a secure communication channel. BodyCom™ Technology works by capacitive coupling to the human body. The human body is used as the secure communications channel between a Base Unit and a Mobile Unit without any form of antenna being required:
BodyCom technology is activated by capacitively coupling to the human body. The system then begins communicating bidirectionally between a centralized controller and one or more wireless units. There are a broad range of applications where secure wireless communication is essential, and there is no more secure channel than the human body. This is especially true when you add bidirectional authentication that supports advanced encryption, such as KeeLoq® technology and AES. For example, BodyCom technology helps prevent the “Relay Attack” problem that is typical in automotive passive-keyless-entry security systems.

BodyCom™ Technology is supported by the free BodyCom Development V1.0 Framework and software libraries that work with all 8, 16 and 32-bit PIC® microcontrollers. The Microchip BodyCom Development Kit is also available to aid development of BodyCom designs.

Enhanced SuperSpeed USB 3.0 specification sees speeds double to 10 Gbps

The development of an updated USB 3.0 specification has been announced by the USB group. A number of enhancements to USB 3.0 are planned, including more efficient data encoding, which will see speeds double to 10 Gbps. The new USB 3.0 (Super Speed) specification should be available around mid 2013 and will be compatible with existing USB 3.0 software stacks, connectors and cables. The new specification is designed to compete with Thunderbolt.

Texas Instruments introduces a new real-time operating system for microcontrollers: TI-RTOS

Texas Instruments has introduced a new real-time operating system for TI microcontrollers: TI-RTOS. The new RTOS is a complete operating system for microcontrollers that provides a real-time multitasking kernel along with additional components including TCP/IP stacks, USB stacks, a FAT file system and other device drivers.

TI-RTOS comes as a free download and is royalty free and works with TI Code Composer IDE v5.2 and above. The new operating system can be configured by means of a graphical tool or a text editor. TI-RTOS is available now for select TI microcontrollers including the ARM Cortex-M4 and the C2000 dual core C28x + ARM Cortex-M3.
