Analog Devices EV Digital Signal Processor
Analog Devices has introduced an embedded system for generating engine sound for electric vehicles (EVs) and hybrid electric vehicles (HEVs). The ADSP-BF706 digital signal processor and Electric Vehicle Warning Sound System firmware allows automobile manufacturers to comply with future safety regulations mandating external engine sound for EVs and HEVs travelling at low speeds.
The ADI solution includes a complete hardware and firmware reference design. It can be scaled for high performance with the ADSP-BF706 or entry-level applications with the ADAU1450 digital audio processor.

Maxim Radiation-Tolerant Secure Authenticator
Maxim has released the DS28E83 DeepCover secure authenticator, allowing medical device designers to protect surgical tool data from memory-disruptive, high-energy gamma radiation used in sterilization, while simultaneously providing tool security with capabilities such as secure tool use management and counterfeit prevention.
The DS28E83 authenticator enhances patient safety and includes both elliptic curve digital signature algorithm– and Secure Hash Algorithm-256–based cryptographic features. The 1-Wire interface also provides simple integration into designs.
Additional technical specifications are available on Maxim’s website.
Microchip 3D Gesture Recognition Controller
Microchip has launched the MGC3140, a 3D gesture recognition controller for automotive HMI designs. Suited for a range of applications that limit driver distraction and add convenience to vehicles, the capacitive technology–based air gesture controller is ideal for navigating infotainment systems, sun shade operation, interior lighting and other applications.
The MGC3140 is Automotive Electronics Council AEC-Q100 qualified with an operating temperature range of –40 to +125°C, and it meets the electromagnetic interference and electromagnetic compatibility requirements of automotive system designs. Each 3D gesture system consists of a sensor that can be constructed from any conductive material, as well as the Microchip gesture controller tuned for each individual application.

Samsung V-NAND Memory Chips
Samsung has announced that it has begun mass production of its fifth-generation V-NAND memory chips. With the use of the “Toggle DDR 4.0” interface, the speed for transmitting data between storage and memory over the 256Gb V-NAND has reached 1.4 gigabits per second, a 40 percent increase from its 64-layer predecessor.Packed inside the V-NAND chips are more than 90 layers of 3D charge trap flash (CTF) cells, stacked in a pyramid structure with microscopic channel holes vertically drilled throughout. These channel holes, which are only a few 100nm wide, contain more than 85 billion CTF cells that can store 3bits of data each. This memory fabrication is the result of several breakthroughs that include advanced circuit designs and new process technologies.
Information concerning pricing and availability can be found on Samsung’s website.
TI DLP Controllers for 3D Printing and Scanning
Texas Instruments has announced DLP Pico controllers that provide light control capabilities in smaller form factors for mass-market 3D scanners and 3D printers. DLPC347x controllers offer the micron-to-submillimeter resolution typically found in industrial-grade applications for desktop 3D printers and portable 3D scanners.
Developers can pair the DLPC3470, DLPC3478 or DLPC3479 controller with one of four existing DLP Pico digital micromirror devices to design a variety of battery-powered and handheld designs.
