Microchip Unveils Wi-Fi Comm Demo Board with 32-bit PIC32 MCU

After TI and Qualcomm, here’s another WiFi solution for MCU aimed at the internet of things (IoT).  Yesterday, Microchip Technology announced the Wi-Fi Comm Demo Board, which combines a Microchip 32-bit PIC32 microcontroller (PIC32MX695F512H) with a low-power MRF24WB0MA embedded Wi-Fi radio transceiver module. This small (and cheap) demo board can be used to integrate with existing embedded designs and/or to evaluate Wi-Fi connectivity with a 32-bit MCU. Contrary to TI and Qualcomm, the IP network stack is not implemented in hardware, but Microchip provides a TCP/IP stack that can be freely downloaded at http://www.microchip.com/get/A3VP.  This TCP/IP stack includes HTML, DHCP, DNS, IPv4/v6, SSL, etc… (See diagram below) The memory footprint is 28-34 KB depending on the modules used. I could not find details about power consumption, but the company claims their solution can also run with just 2 AAA batteries. Microchip explains that this solution can enable the rapid growth […]

Qualcomm Atheros AR4100P Provides WiFi Connectivity to the Internet of Things

In January, Texas Instruments was the first company (to my knowledge) to release a WiFi chip for the internet of things, the SimpleLink Wi-Fi CC3000, where WiFi is mostly implemented in hardware to lower power consumption. Now, the company has some competition with the announcement of Qualcomm Atheros AR4100P, an improved version of its AP4100 WiFi chipset, including IPv4/IPv6 support. The AR4100 targets the home, enterprise, smart grid and home automation and control applications that have lower data rates and transmit or receive data on an infrequent basis. The AR4100 system-in-package (SIP) features the following: Low energy Power saving modes as low as 5 µA Wake-up times as low as 2.2 ms Support for Quad SPI flash for faster wake times Low system resource requirements Low footprint host driver (25K Flash and 8K RAM) Simple, low-cost wireless system integration LGA package simplifies 2- or 4-layer PCB design Near zero RBOM […]

uClinux Running on Freescale Kinetis K70 MCU (Cortex-M4) Module

Last year, I posted about Linux for Cortex M3 & M4 Micro-controllers and noted it was difficult to find cost effective Cortex-M based boards able to run uClinux or Linux (RAM being the main issue). Freescale TWR-K70F120M  is a module based on Kinetis K70 MCU (Cortex M-4) with plenty of RAM (128MB) to run Linux or uClinux. It is available for 109 USD or 179 USD with Freescale Tower system (TWR-K70F120M-KIT). Here are the key features of the module: Freescale MK70FN1M0VMJ12 Cortex-M4 MCU @ 120 MHz (Product Brief) Touch Tower Plug-in Socket General purpose Tower Plug-in (TWRPI) socket On-board JTAG debug circuit (OSJTAG) with virtual serial port 128 MB DDR2 SDRAM memory 256 MB SLC NAND flash memory Three axis accelerometer (MMA8451Q) Potentiometer Micro-SD Card slot I could not find an open source uClinux implementation for Kinetis K70, but emCraft has a Linux Board Support Package (BSP) for the Freescale TWR-K70F120M-KIT […]

Samsung Exynos 5250 Dual-core Cortex A15 and GAIA SMDK Development Board

Samsung showcased its new Exynos 5250 Dual-core Cortex A15 processor at Mobile World Congress as well as the corresponding Samsung Exynos 5 GAIA SMDK Development board. Announced in November 2011, the new Samsung Exynos 5250 processor features 2 Cortex A15 clocked at 1.7 GHz or 2 GHz, with a Mali-T604 GPU and support for dual-channel 800 MHz LPDDR3 RAM that allows for a data bandwidth of up to 12.8 GB/s. The processor is manufactured using 32-nm HKMG (High-K Metal Gate) technology that reduces leakage by 30% proving lower power consumption. Samsung claims the new Exynos 5 processors are twice as fast and consume twice as less power than its previous Exynos 4 application processor based on Cortex A9. This seems to confirm TI OMAP 5 vs. Nvidia Tegra 3 benchmark results. The Exynos 5250 supports embedded DisplayPort  (eDP) interface up to WQXGA resolution (2560×1600), which is handy for Samsung since […]
