ARM Announces Ultra Low Power Cortex-M0+

Today ARM introduced the Cortex-M0+ as the "world's most energy-efficient processor" in a press release.  Both Freescale and NXP have announced they will license the core in today's press releases that coincide with ARM's announcement.

Freescale is introducing the Kinetis L series as the first microcontroller to be built on the Cortex-M0+.
They list some new features of the ore including reducing the pipeline to two stages, single-cycle access to I/O, faster access to program memory, linear address space and a micro trace buffer.  Freescale has functional silicon today according to the following YouTube video.

NXP's announcement talks about the success they have had with the predecessor Cortex-M0 core.  They currently have the lowest power Cortex-M0 at 110uA/MHz, licensing the new Cortex-M0+ will enable them to continue to offer the lowest power ARM processors.  The new license is part of NXP's strategy to offer the widest range of ARM solutions as you can see in this interview.

NXP Android Accessory Kit Includes Two ARM Development Boards

Embedded Artists and NXP have developed the Android Open Accessory Application Kit (AOAA).  The kit implements a USB host interface and the Android accessory protocol used by the Android Open Accessory Development Kit (ADK)  An added bonus to this $79 US development kit is an ARM Cortex-M0 board that is detachable from the main board and features the  NXP LPC11C24 microcontroller  The main board uses an ARM Cortex-M4 NXP LPC1769 that interfaces with the second ARM through a CAN interface.

Here is a video presentation from NXP about the kit.

To purchase the kit visit the embedded artists AOAA page, it can be purchased direct or through distributors including Digi-Key and Mouser.   The embedded artists page also includes documentation and software downloads.  In addition, there is a kit resource page at the LPCware NXP community.

Tiny Serial WiFi Module Includes ARM Cortex M3

The Inventek Systems 802.11 b/g/n Serial to WiFi module makes it easy to add Wi-Fi to your embedded design.  It can be programmed from a host with a choice of serial interfaces using a simple AT command set.

These serial interfaces are provided by an STM32 ARM Cortex M3 processor as shown on the block diagram.  No software development is required for the STM32, the AT command set interface is resident in firmware.  This means your host microcontroller does not need a TCP/IP stack or RTOS.  This simplifies software development for your application - you only need to write serial I/O code to send the AT commands and process data.

An embedded wireless evaluation board is available that make it easy to connect the module to your microcontroller board for development of your WiFi application.  Both the evaluation board and the module are available from the Inventek Systems online store.

For more information on the module and evaluation board watch this video that includes a description of the functional block diagram above.
