pulse Barometric pressure sensor – accurate altitude tracking for consumer devices Bosch Sensortec’s BMP380 is the company’s smallest and best performing barometric pressure sensor, with a size of 2.0 x 2.0 x 0.75 mm. It can be applied in a range of altitude tracking applications, with improved accuracy and smaller footprint over previous parts, and with reduced power consumption. Pressure and temperature data can be stored in a built-in 512 Byte FIFO; the FIFO and interrupt functionality provide simple access to data and storage. This improves ease of use while helping to reduce power consumption to 2.7 μA at 1 Hz during full operation. The sensor is more accurate than its predecessors, covering a wide measurement range from 300 hPA to 1250 hPA. Tests in real-life environments have verified a relative accuracy of ±0.06 hPa (±0.5m) over a temperature range from 25°C to 40°C. The absolute accuracy between 300 and 1100 hPa is ±0.5 hPa over a temperature range from 0°C to 65°C. The BMP380 is aimed at gaming, sports and health management, as well as indoor and outdoor navigation. By measuring barometric pressure, the sensor enables drones, smartphones, tablets, wearables and other mobile devices to accurately determine altitude changes, in both indoor and outdoor environments. Typical applications for the BMP380 include altitude stabilization in drones, where altitude information is utilized to improve flight stability and landing accuracy. Cryptographic controller for embedded devices Maxim Integrated has posted initial details of its Deep- Cover cryptographic controller, MAXQ1061, designed to protect the confidentiality, authenticity and integrity of software IP, communication and revenue models, in connected embedded devices, industrial networking, PLC, and network appliances. Maxim describes the device as a turnkey solution for secure storage, digital signature, encryption, secure boot, and TLS/ SSL communication. DeepCover embedded security devices apply multiple layers of advanced physical security to provide the most secure key storage possible. An embedded cryptographic toolbox provides key generation and storage up to full SSL/TLS/ DTLS support by offering a high level of abstraction including TLS/ DTLS key negotiation, ECDSAbased TLS/DTLS authentication, digital signature generation and verification, SSL/TLS/DTLS packet encryption, and MAC algorithms. It can also serve as a secure bootloader for an external generic microcontroller. 32 kB of user-programmable EEPROM Complete article, here securely store certificates, public keys, private and secret keys, monotonic counters, and arbitrary data. A flexible file system manages access rights for the objects. The device is controlled over a SPI or I²C interface. Protocols for life cycle management and a secure key loading are provided.
