Qorvo GP695 “Smart Home” SoC Integrates 802.15.4, Zigbee 3.0, Thread, and Bluetooth LE

GreenPeak Technologies ultra-low power, short range RF communication technology company was acquired by Qorvo last year, and Qorvo has recently announced a GP695 system on chip (SoC) for smart home devices part of GreenPeak’s previous family of devices, and supporting multiple short range RF protocols. GP695 key features: MCU Core – ARM Cortex M4 Connectivity IEEE 802.15.4 ZigBee 3.0 Thread Bluetooth Low Energy (BLE) Qorvo Wi-Fi interference mitigation technology GP695 has been designed to be used in device such as a door locks, smart HVAC, smart security systems, connected video doorbells and intercoms, lightbulbs, smoke alarms, and leak detectors, and complements GP712 multi-protocol SoC designed for smart home gateways. Qorvo will feature live demonstrations of its smart home and IoT solutions at its booth during CES 2017, at Sands Expo, Halls A-D Booth #42114. There’s very limited public information, and no product page could be found in their website. Jean-Luc […]

Allwinner V3s Dual Camera SoC Comes with 64MB DRAM

Most SoCs have a very limited amount of internal SDRAM just enough to load the bootROM code, but a few integrated a few MB of RAM on-chip such as Renesas RZ/A1H with 10MB on-chip DRAM, in order to reduce costs for some applications that may not require external RAM. Allwinner V3s, designed for dual camera solutions, appeared to be such an SoC with 64MB (512Mbit) on-chip DDR2 RAM, but the block diagram seems to imply it is a System-in-Package (SiP) instead. Nevertheless you still get a single chip with an ARM Cortex A7 processor, two ISPs, a video engine, 64MB RAM, and more. Allwinner V3s main features & specifications: CPU – ARM Cortex-A7 @ up to 1.2 GHz Memory – Integrated 64MB DDR2 DRAM Storage I/F – SD 2.0, eMMC 4.41, SPI NAND flash, SPI NOR flash Audio Codec – 92dB audio codec supporting 2x ADC channels and 2x DAC […]

Vorke Z3 Rockchip RK3399 TV Box to Launch in February 2017

I was expecting devices based on Rockchip RK3399 hexa-core processor to launch by the end of this year, that is about right now, but finally it looks like products will only start the show by the end of Q1 2017, as Firefly-RK3399 development board is scheduled to ship to backers in March 2017, while GeekBuying has started teasing us with their Vorke Z3 TV box powered by Rockchip RK3399 with 4GB RAM slated to launch in February 2017. [Update: Vorke Z3 is now up for sale for $169.99 including shipping] Vorke Z3 preliminary specifications: SoC – Rockchip RK3399 hexa-core processor with  2x ARM Cortex A72 cores at up to 2.0GHz, 4x Cortex A53 cores, and an ARM Mali-T860MP4 GPU System Memory – 4GB LPDDR3 Storage – 32GB eMMC flash, external SATA interface (hopefully implemented via the PCIe interface), micro SD slot Video Output – HDMI 2.0 up to 4K @ […]

Ambiq Micro Introduces Ultra-Low Power Apollo 2 Cortex-M4F MCU Consuming Less than 10 μA/MHz

Last year Ambiq Micro unveiled their Apollo Cortex-M4F MCU with Cortex M0+ energy efficiency thanks to operation in sub-threshold voltage (< 0.5 V), and the MCU is said found in Matrix Powerwatch, a fitness tracker powered by body heat that you never need to charge. The company has recently announced a new version of the micro-controller with Apollo 2 MCU with better maximum performance thanks to a higher maximum clock speed (48 MHz vs 24 MHz), and higher efficiency (10 μA/MHz vs 30 μA/MHz @ 3.3V). Apollo 2 MCU key features and specifications: Ultra-low supply current <10 μA/MHz executing from flash at 3.3 V <10 μA/MHz executing from RAM at 3.3 V ARM Cortex-M4 Processor up to 48 MHz with FPU, MMU, wake-up interrupt controller with 32 interrupts Ultra-low power memory Up to 1 MB of flash memory for code/data Up to 256 KB of low leakage RAM for code/data […]

Arduino MKRZero is a Smaller Arduino Zero Board

Arduino Zero was unveiled over two years ago with an Atmel SAMD21G18  ARM Cortex M0+ MCU in Arduino Uno Rev.3 form factor, the company has now launched Arduino MKRZero with the same MCU but using the much smaller Arduino MKR1000 form factor. Arduino MKRZero specifications: MCU – Atmel/Microchip SAMD21 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash (8KB for bootloader) External Storage – micro SD slot Digital I/O Pins – 22x GPIOs with 12x PWM, UART, SPI, and I2C, 8x external interrupts Analog Pins – 7x analog inputs (8/10/12-bit ADC), and 1x analog output (10-bit DAC) DC Current per I/O Pin – 7 mA USB – 1x micro USB port for power and programming Debugging – USB via Atmel’s Embedded Debugger (EDBG) on-board debugger, and JTAG Misc – reset button, 1x LED (pin 32), 32.768 kHz RTC Power 5V via micro USB port […]

Avantek H270-T70 384-core ARM Server Powered by Cavium ThunderX SoCs Can Be Bought Online

ARM servers have been around for a while, but usually it’s pretty hard to buy for individuals, and developer’s boards such as LeMaker Cello are never in stock, probably because the project has been canceled or suffered from further delays. However, if you have some uses for ARM servers and the cash that goes with it, Avantek Computer (UK) is selling some ARM based servers starting from an 1U Rack with a quad core Annapurna Alpine AL5140 processor up to Avantek H270-T70 with a 2U rack equipped with multiple Cavium ThunderX SoCs providing 384 ARMv8 cores to play with. Avantek H270-T70 server key features and specifications: SoCs – 8x Cavium ThunderX CN8890 processors with 48 custom ARMv8 cores each System Memory – 64x DDR4 ECC slots for up to 8TB memory Storage – 16x 2.5” hot-swappable HDD/SSD bays Connectivity – 8x 40GbE QSFP+ fiber ports (Cortina CS4343 controllers) Power Supply – […]

Linux 4.9 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux 4.9 on Sunday: So Linux 4.9 is out, and the merge window for 4.10 is thus open. With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into Xmas food prep, even that date might be questionable. I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last […]

Qualcomm Starts Sampling of Qualcomm Centriq 2400 ARM Server SoC with Up to 48 ARMv8 Cores

Qualcomm has announced commercial sampling of Qualcomm Centriq 2400 series server SoC built with 10nm FinFET process technology and featuring up to 48 Qualcomm Falkor custom ARMv8 CPU cores “highly optimized to both high performance and power efficiency, and designed to tackle the most common datacenter workloads”. Qualcomm Datacenter Technologies demonstrated the new processor in a Live demo showing Apache, Spark, Java, and Hadoop on Linux running on a SBSA compliant server powered by Qualcomm Centriq 2400 processor, but the company did not provide any further technical details or preliminary benchmark results for the solution. The Qualcomm Centriq 2400 processor series is now sampling to select customers and is expected to be commercially available in H2 2017. That’s about all we know from the press release. However, Linaro have been working on Qualcomm Technologies QDF2432 based board for several months with support for Debian 8.x ‘Jessie’ and CentOS 7 operating […]
