Ambiq Micro Apollo Low Power MCUs Promise Cortex M4F Performance at Cortex M0+ Energy Efficiency

Ambiq Micro is a US company founded in 2010 that focuses on “extremely low power” semiconductors leveraging their patented Subthreshold Power Optimized Technology (SPOT) platform. Earlier this year, they announced their first low power Cortex-M4F MCU Apollo family with claims of 5 to 10 times lower power consumption compared to other micro-controllers with the same performance. According to an EETimes article, they’ve at least partially backed their claims with a live demonstration at ARM TechCon 2015. Before checking out the test results, let’s have a look at the main features of Apollo MCU family: 32-bit ARM Cortex-M4F processor @ up to 24 MHz, with FPU, and wake-up interrupt controller with 12 interrupts Up to 512KB flash, 64-KB low-leakage RAM “Rich set of timing peripherals” Peripherals I2C/SPI master; I2C/SPI; UART; 10-bit, 13-channel, 1MS/s ADC Temperature sensor with ±2°C accuracy Voltage Range – 1.8 to 3.8V Power Consumption: active mode: 30µA/MHz (executing […]

Turris Omnia Open Source Hardware Router’s Crowdfunding Campaign is Up

CZ.NIC is a non-profit organization running the .cz domain of the Czech Republic, and as part of their activities they are also making open source hardware routers such as Turris 1.1 based on Freescale QorIQ P2020 communication processor. I’ve previously written about Turris Omnia router based on Marvell ARMADA 385 dual core processor, and the organization has now launched an Indiegogo campaign where you can get the bare board for $99, and a complete router with WiFi modules, power supply, cables, and enclosure for $189, shipping not included. Turris Omnia router specifications: Processor – Marvell ARMADA 385 (88F6820) dual core ARMv7 processor @ 1.6 GHz with 1MB L2 cache System Memory – 1GB DDR3 Storage – 4GB flash, mSATA slot Connectivity 5x Gigabit Ethernet LAN ports 1x Gigabit Ethernet WAN port 1x SFP cage 3×3 MIMO 802.11ac, 2×2 MIMO 802.11 b/g/n (Included in router perk, not with bare board) SIM […]

GTEK GP100 Rugged Waterproof Bluetooth Speakers Can Be Used in the Bathroom and Outdoors

I normally put my smartphone on a shelf to listen to music while taking a bath or showering, and a few years back I thought about using Bluetooth speakers, but few solutions were waterproof, and/or the price must have been high, so I forgot about it. Following a post on ARMDevices.net about GTEK speakers, I found out there are now many waterproof Bluetooth speakers to choose from with prices starting as low as $7. But I found GTEK GP100 speakers quite interesting, as beside being waterproof (IPx7), there are also rugged and suitable for outdoor activities, come with a 3,000 mAh battery good for 8 to 10 hours, and can fit into your bicycle bottle’s holder. Some of key features of GTEK GP100 (GT-D201): Connectivity – Bluetooth 3.0 (Website also says Bluetooth 2.1 + EDR); 10 meter range Speakers – 2x 5W (or 3W?); 80db+ SNR; 80Hz – 18Khz frequency […]

Newracom NRC6101 802.11ah WiFi SoC Promises up to 1 km Range for Smart Grid and Automation

802.11ah is a new WiFi standard operating in the 900 MHz range that targets low power & long range connectivity, as required by many IoT & M2M applications. According to this low power WAN standards comparison table, 802.11ah also supports up 1km range outdoor, 150 Kbps to 346 Mbps transfer rates, up 8191 clients per access points, and a 2016 launch is planned. However, I had not seen any implementations based on the new standard, except a demonstration by Antcor on a DSP in 2014. A Korean startup, Newracom, may however soon launch the first 802.11ah chip with NRC6101 SoC. I was tipped about this new solution via a Korean website, where I got the picture above from, but there’s no information about NRC6101 on the web, except for a small mention on Wikidevi.com redirecting to the product page, where NRC6101 name is not even mentioned, but with some specifications […]

Run x86 Linux and Windows applications in Raspberry Pi and other ARM Linux Devices with Exagear

A few weeks ago, I finally decided to buy a Raspberry Pi 2 board as it could always be useful for some testing, at least for comparison purposes. I ended up buying it from Ebay for $40, as it’s $3 to $5 more expensive locally. Nevertheless, I was not sure what I’ll use it first for, but after seeing a tweet for Exagear Desktop software that allows ARM boards to run x86 Linux or Windows applications, the latter through wine. The program is available for Raspberry Pi, Raspberry Pi 2, and ARMv7 devices for $19.95 to $29.95. I asked for a version for testing purposes, and I was given a Google Drive link to download Exagear for Raspberry Pi 2, as well as a 3-month trial key. Installation is very easy. I started by downloading and installing Raspbian Jessie the usual way on a 32GB micro SD card. It went […]

Samsung Exynos 8890 Octa-core Processor to Feature Custom ARMv8 Cores and Mali-T880 GPU

Samsung Exynos 7420 processor is at the top of benchmark charts for smartphones, but the company is still pushing for more performance and power efficiency with their upcoming Exynos 8890 processor that promises 30% improvements in performance, and 10% in power efficiency. While Exynos 7 Octa was made with ARM’s own Cortex A53 and A57 cores, Samsung did not go with Cortex A72 in 8890, but instead decided to design their own ARMv8 cores and coupled for of these with four low power ARM Cortex A53 cores, and a Mali-T880 GPU. Samsung also included a LTE Rel.12 Cat.12/13 modem that enables speeds up to 600Mbps DL (Cat.12) and 150Mbps UL (Cat.13), and the processor will be manufactured using 14nm FinFET process technology. Excluding the custom cores, and the manufacturing process, this configuration is similar to the recently unveiled Huawei Kirin 950 processor using four Cortex A72 cores and TSMC 16nm […]
