Cypress Semiconductor has announced it has collaborated with Semtech on a compact, two-chip LoRaWAN-based module deployed by Onethinx. The highly-integrated Onethinx module is ideal for smart city applications that integrate multiple sensors and are in harsh radio environments. Using Cypress’ PSoC 6 microcontroller’s (MCU) hardware-based Secure Element functionality and Semtech’s LoRa devices and wireless radio frequency technology (LoRa Technology), the solution enables a multi-layer security architecture that isolates trust anchors for highly protected device-to-cloud connectivity.
In addition, the PSoC 6 MCU’s integrated Bluetooth Low Energy (BLE) connectivity provides a simple, low-power, out-of-band control channel. The PSoC 6 device is the industry’s lowest power, most flexible Arm Cortex-M dual-core MCU with a power slope as low as 22-μA/MHz active power for the Cortex-M4 core. The device is a natural fit with Semtech’s latest LoRa radio chip family, which offers 50% power savings in receive mode and 20% longer range over previous-generation devices.
Security is a primary concern for many smart city applications. The Onethinx module utilizes the integrated Secure Element functionality in the PSoC 6 MCU to give each LoRaWAN-based device a secret identity to securely boot, on-board, and deliver data to the cloud application. Using its mutual authentication capabilities, the PSoC 6 MCU-based, LoRa-equipped device can also receive authenticated over-the-air firmware updates.
Key provisioning and management services are provided by IoT security provider and member of the Bosch group, ESCRYPT, for a complete end-to-end, secure LoRaWAN solution. The module, offered by Cypress partner Onethinx, connects to Bosch Sensortec’s Cross Domain Development Kit (XDK) for Micro-Electromechanical Systems (MEMS) sensors and to the provisioning system from ESCRYPT to securely connect.

MediaTek has announced the MT6795, which the company is targeting at the high-end Android 4G smartphones and tablet segment. According to the press release, the eight-core processor also supports 2560 × 1600 resolution displays, FDD/TDD LTE technology, 802.11ac WiFi, Bluetooth, GPS, FM Radio, and 2G and 3G wireless networks.
The chip also supports video recording and playback at Ultra HD (4K2K) resolution using the H.265, H.264 and VP9 formats, supporting high-speed 1080p video recording at up to 480 frames per second allowing slow-motion playback on screens with 120 Hz refresh. An integrated 16-MP camera image signal processor handles video input and MediaTek’s ClearMotion technology eliminates motion jitter to ensure smooth video playback at 60fps.
The MT6795 uses eight ARM Cortex-A53 processors, based on a 28-nm process that clocks at 2.0 GHz and a Mali-T760 GPU to handle display control. MediaTek also supplies its CorePilot technology, which provides multicore processor performance and thermal control of the chip. The MT6795 also supports dual-channel LPDDR3 memory at 933 MHz.
According to MediaTek, we can expect to see 4G smartphones using MT7695 chips before the end of 2014.
The M-5360A is an application-ready solution for multimedia and machine-to-machine (M2M) applications. The credit card-size System on Module (SOM) is powered by a Freescale 800-MHz i.MX537 ARM Cortex A8 processor with 1-GB DDR3 RAM and 4-GB eMMC flash.
The M-5360A features two independent low-voltage differential signaling (LVDS) channels for dual LCDs and one VGA port for external monitor connection. The i.MX537’s multimedia and graphic engine supports OpenGLE 2.0, OpenVG 1.1 graphics acceleration, and 1080P video decoding.
The M-5360A also provides powerful communication functionality (e.g., Ethernet, RS-232, RS-485, CAN 2.0, 1-Wire, and USB). This makes the SOM suitable for multimedia applications as well as embedded networking devices.
The M-5360A uses 128-pin 2-mm pin headers, which simplifies application board design. The SOM includes a preinstalled Ubuntu OS. Android and Windows CE are available by request. In addition to the hardware building blocks, software utility and device drivers are available for user applications.
