Lowest Power Bluetooth in the World: Atmel BTLC1000 Bluetooth for IoT on ARM Cortex-M0 with up to 9 years of battery life
The Atmel BTLC1000 Bluetooth Smart SoC can run at sub-1µA in standby mode in a 2.1mmX2.1mm Wafer Level Chipscale Package (WLCSP), while delivering the industry’s best dynamic power consumption with a potential battery life of up to 9 years on a coin cell battery. Atmel designed BTLC1000 specifically for the rapidly growing IoT and for wearables market, including portable medical, activity trackers, human Interface devices, gaming controllers, beacons and much more.
Expanding upon the Atmel SmartConnect wireless portfolio, the BTLC1000 is a Bluetooth Smart link controller integrated circuit that connects as a companion to any Atmel AVR or Atmel | SMART MCU through a UART or SPI API requiring minimal resource on the host side. The standalone Atmel | SMART SAMB11 Bluetooth Smart Flash MCU leverages the embedded ARM Cortex-M0 core combined with the integrated analog and communication peripherals to implement application-specific functionalities and is available as a system-in-package or a certified module. Both devices are fully integrated with a self-contained Bluetooth Smart controller and stack enabling wireless connectivity for a variety of applications to be quickly implemented without the wireless expertise typically required.
In this interview, Free Electrons CTO Thomas Petazzoni and Opersys founder Karim Yaghmour exchange some thoughts about embedded Linux vs. Android, and then Thomas moves on to describe in more details the activities of the embedded Linux services company Free Electrons. Both Free Electrons and Opersys are unique amongst others things by the fact that they provide all their training materials freely on the web! Thomas also discusses the numerous Linux kernel contributions made by Free Electrons, which is ranked the 7th contributing company for the next Linux kernel release, in number of patches, an impressive result for a 9 persons business: Free Electrons has developed a core expertise in pushing the support for ARM processors to the upstream Linux kernel. More specifically, the work done by Free Electrons engineers on Atmel ARM platforms is presented, since Free Electrons was demonstrating an Atmel SAMA5D3 platform with a brand new DRM/KMS graphics driver that has been developped by Free Electrons engineer Boris Brezillon and recently merged in Linux 4.0.
Cypress makes programmable system-on-chip solutions used in a wide range of applications, from consumer and automotive to industrial and military products. They are launching the $10 CY8KIT-059 development board to program their ARM Cortex-M3 PSoC 5LP at http://www.cypress.com/?rid=108038 The Cypress PSoC platform includes several families of devices that feature an ARM Cortex processor surrounded by a host of programmable analog and digital resources that can easily be customized with a simple drag-and-drop design tool called PSoC Creator. Cypress’s newest PSoC innovation includes the PSoC 4 M-Series, which, with its 32-bit ARM Cortex M0- core, 128KB of flash, programmable analog and digital components, dual CAN interfaces and 55 GPIOs, make it an ideal replacement for standard 8-bit and 16-bit applications. Another recent Cypress innovation is the Cypress PSoC 4 BLE, which adds Bluetooth Low Energy connectivity to any device, and is ideal for a variety of wireless applications from fitness and health-monitoring wearables to sensor-based systems in homes.
The Atmel | SMART SAM S70 and E70 microcontrollers are based on the high-performance 32-bit ARM Cortex-M7 RISC processors with double precision floating point unit. They operate at a maximum speed of 300MHz and feature up to 2048KB of Flash, dual 16KB of cache memory and up to 384KB of SRAM. They can achieve 1500 CoreMarks or up to 645 DMIPS. On the memory side, they have a flexible SRAM which can be configured as Tightly Coupled Memory (TCM) up to 256KB. Allowing execution of deterministic code or fast processing data. Code executed from TCM is executed at full speed so at 300MHz. The SRAM is multi-port which is reducing the latency over the bus matrix. When they have a lot of burst the latency can be reduced by 16 thanks to the 4 ports. To accelerate the execution of the code from on-chip Flash or nonvolatile memory connected to QuadSPI or over the External Bus Interface, they have integrated a huge L1 cache of 16kByte for the instruction and 16kByte for the data. Both with ECC. The 384KByte of SRAM can be extended through the SDRAM interface. Looking at the features now, they have plenty of serial communications such as SPI, SDIO or USART. Atmel has one High-speed USB Host and Device, with integrated PHY which obviously save some cost and PCB space. There is one CMOS Camera interface for image acquisition. All the series offer two Advanced Analog Frontend (AFE) with Dual Sample and hold capability and Up to 16-bit resolution with hardware oversampling. They also have programmable Gain for small signal input. All series offer real-time event management through direct connection between PWM, Timer and ADC for motor control application. Both series are based on the same feature set, the only difference is coming from the Ethernet, CAN support (SAME70 integrates Ethernet and CAN). Atmel offers all series in BGA and QFP from 64 to 144 pins. Small 64-pin pincount option offers an entry level form factor high performance MCU. All series support the extended Industrial temperature range from -40 to 105°C.
Xilinx announces their next generation 16nm FPGA with quad-core ARM Cortex-A53 and dual-core ARM Cortex-R5, Mali400 GPU. The FPGA market is for designs where flexibility, high performance and fast time to market is important providing programmable hardware. The silicon is going to be available at the end of this year, so they are for now showing emulated version of their SoC. The dual-core ARM Cortex-R5 on the SoC are used for increased safety and security. By going with a 16nm 64bit design, Xilinx can pack a lot more performance without consuming more power than their previous dual-core ARM Cortex-A9 based Zynq 7000 which I filmed here http://armdevices.net/2011/03/04/xilinx-zynq-7000-series-cortex-a9-in-fpga-at-embedded-world-2011/
