Atmel SAM S70 and SAM E70 Cortex M7 MCUs, SAM V71 Xplained Board Are Now Shipping

ARM Introduced Cortex M7 IP in September, and ST Micro simultaneously announced its STM32F7 Cortex M7 MCU clocked up to 200 MHz, and boards are now available, including some running Linux. But two other companies have licenses Cortex M7, Freescale with its Kinetis KV5x micro-controllers which are yet to be mass-produced, and Atmel which has recently announced their SAM S70 and E70 micro-controllers are now in mass production. SAM E70 and S70 have similar features, but E70 offers some extra interface like CAN and Fast Ethernet: ARM Cortex-M7 core running at up to 300MHz (1500 CoreMark) Up to 2MB Flash and 384kByte SRAM Floating point unit (FPU) for high-precision computing and accelerated data processing High-performance internal memory architecture with user configurable Tightly Couples Memories and System memory, and 16kB I and D-cache High Speed USB Host and Device with on-chip high-speed PHY CMOS image sensor interface AES hardware encryption engines, […]

Embedded Systems Conference 2015 Schedule – May 6-7, 2015

The Embedded Systems Conference took the name “Design West” for a couple of years, but this year, there’s no mention of Design West, and the Embedded System Conference 2015 will take place in Boston, MA, US on May 6-7, 2015. The 2-day event will have a demo hall, and well as sessions divided into 8 tracks: Connected Devices and the IoT Embedded Software Design Hardware: Design, I/O and Interfacing Prototyping Embedded Systems Design Software: Design, Languages, & Quality Fantastical Theater Teardowns The full schedule has now been posted, and I’ll build a virtual schedule with some of the sessions provided. Wednesday May 6, 2015 8:00 – 8:45 – Understanding Google/Nest Thread by Michael Anderson, Chief Scientist, The PTR Group, Inc. The IoT will live or die based on its connectivity. In examining existing wireless protocols, Google/Nest found most of them lacking. In order to address the needs for low-power wireless […]

Freescale Announces i.MX 6SoloX ARM Cortex A9 & Cortex M4 Processor

Freescale i.MX6 SoloX processor started to show up in the ARM Linux Kernel mailing list last year, and Cortex A9 + Cortex M4 processor showed up in some marketing documents, but so far all documentation was tied to a non-diclosure agreement. However, all resources are now publicly available, as the company officially launched i.MX 6SoloX processor at Embedded World 2015. Freescale i.MX 6SoloX specifications: CPU – ARM Cortex-A9 up to 1 GHz with 512 KB L2 cache, 32 KB instruction and data caches and NEON SIMD media accelerator MCU – ARM Cortex-M4 up to 200 MHz with 16 KB instruction and data caches, 64 KB TCM, MPU and FPU Memory Interface 16/32-bit DDR3-800 and DDR3L-800, 16/32-bit LPDDR2-800 SLC/MLC NAND, 62-bit ECC, ONFI2.2 2x DDR Quad SPI NOR flash, 16/32-bit NOR Flash Display and Camera Interfaces Parallel RGB LVDS 20-bit parallel CMOS sensor interface NTSC/PAL analog video input interface Multimedia GPU […]

Intel Curie Board Designed for Wearables is Powered by Quark SE SoC

Intel announced the Edison board at CES 2014, a board targetting wearables and IoT applications about the size of an SD card. At CES 2015, the company has gone smaller, by unveiling the button-sized Intel Curie module powered by a new Intel Quark SE SoC with a motion sensor, Bluetooth Low Energy connectivity and battery charging capabilities. Intel Curie specifications: Low-power, 32-bit Intel Quark SE SoC 384kB Flash memory, 80kB SRAM Low-power integrated DSP sensor hub with a proprietary pattern matching accelerator Bluetooth Low Energy 6-axis combo sensor with accelerometer and gyroscope Battery charging circuitry (PMIC) The module runs an unnamed open source RTOS, and the company will provide IQ software kits for references applications for wearables, such as counting steps, apps for mobile device, and so on. Intel Curie is  expected to be found in smart products such as rings, bags, bracelets, pendants, fitness trackers and buttons. There’s basically no […]

Fernvale Open Source Hardware IoT Board Based on Mediatek MT6260 SoC with GSM Connectivity

Andrew Huang (Bunnie), an hardware engineer, known for hacking the original XBOX, and more recently for Novena open source laptop, has decided it could be interesting to reverse-engineer Mediatek MT6260 processor, as in China, it’s difficult to get documentation, SDK, and tools if you don’t commit to purchase X chips, where X is a rather large number. He and others also checked whether their work could be open sourced legally, and assert their “fair use” rights to reverse-engineer hardware and firmware. And so Fernvale project was born both as a technical challenge and to make a point. MT6260 is a $3 ARM7EJ-S processor clocked at 364 MHz with 8MB built-in RAM, interfaces such as I2C, SPI, PWM, UART, as well as LCD and touchscheen controller, and audio codec, battery charger, USB,  Bluetooth, and GSM support, which make the $6 Atmel MCU used in Arduino board look expensive. The main differences […]
