MEMS micro-spectrometer covers the 340 to 850nm spectral range Hamamatsu Photonics’ latest MEMS spectrometer, the C12880MA, comes in a fingertip sized package with a spectral range of 340 to 850nm and a sensitivity two orders or magnitude higher than the company’s original C12666MA micro-spectrometer. The chip offers 12nm resolution, a high speed video rate of 5MHz and incorporates a trigger function and a CMOS sensor with 288 pixels (14x200 um pixel size). The whole unit measures only 20.1×12.5×10.1mm, making it suitable for portable measurement devices in applications such as colour monitoring, LED testing, water quality monitoring and other environmental measurement instruments. Hamamatsu www.hamamatsu.com Freescale specs analog IC for motorcycles’ ABS Measuring only 7x7mm, Freescale Semiconductor’s SB0400 and SB0401 analog ICs were specifically engineered for motorcycle and scooter’s anti-lock braking systems (ABS), helping ECU manufacturers reduce the cost, size and weight of the electronic control units. The two-wheel SB0400 IC is designed for use with motorcycles, while the singlewheel SB0401 IC is intended for scooters and lighter motorcycles. Both products are leadless, and neither require bulky heat sinks, saving system cost and space. Built on Freescale’s SMARTMOS analog-mixed signal technology, they integrate an ABS system’s wheel speed sensor interface, valve drivers, motor pump driver, safety switch and safety state machine into the smallest package size available on the market for motorcycle and/or scooter designs. This product introduction coincides with the upcoming initial implementation of European Commission legislation making ABS mandatory for all new motorcycles above 125cc, beginning 1 January 2016. Integrated hardware safety functions for protection/diagnostics include over-voltage (OV), under voltage (UV), over temperature, short and open load detection. Freescale www.freescale.com/SafeAssure Radiocrafts announces Sigfox-ready RF module Radiocrafts AS has released a Sigfox-ready radio module for IoT applications. Measuring 12.7x25.4mm and delivered in a surface-mount, tape and reel packaging, the compact RF module has been certified to assure optimal connectivity performance on the Sigfox global network. Based on ultranarrowband (UNB) technology, the new Radiocrafts module has achieved best-in-class designation for receiver sensitivity and range. The RC1682 module with embedded Sigfox protocol is said to provide a robust data link and is very easy to use and add to any sensor monitoring or control application. It features very high spectral efficiency, with temperature stabilized crystal oscillators to ensure reliable operation over the full industrial temperature range, -40 to +85 degrees Celsius. Samples and Demo Kits are available now. Radiocrafts www.radiocrafts.com NFC analog front end targets smartwatches and wearable devices The company, ams AG has announced an NFC (Near Field Communications) analog front end (AFE) for manufacturers of smart watches, wristbands and other space-constrained devices, enabling them to reliably support contactless payments and ticketing. The AS3921 NFC analog front end features boostedNFC technology from ams, which increases the useable operating volume of an NFC reader by up to 900% when compared to conventional NFC implementations. This greatly improves the reliability and perceived speed of NFC transactions, particularly in devices such as smart watches and wristbands that only have room for an extremely small antenna. It also ensures reliable NFC transmission in other device types which have a smaller antenna than that of a contactless card, or which present difficult operating conditions for NFC transmissions. Optimised for space-constrained assemblies, the AS3921 enables OEMs to implement a simpler design than the conventional NFC controller-based architecture allows, resulting in a simpler and cheaper system, occupying a board footprint around one third smaller, using fewer components and consuming less power. Drawing just 12 μA in normal operation, and providing a power-saving Secure Element wake-up function, the AS3921 drains far less power from the battery than NFC controller circuits, which typically draw 60 μA or more. Packaged in an ultra-compact wafer-level chip-scale package (WL-CSP) measuring just 2.115x1.735mm, and connecting directly to the Secure Element with few external components required, the AS3921 with boostedNFC technology implements active load modulation: it generates an RFID card response which is synchronous to the reader’s field. This allows for card-to-reader communication at coupling factors as much as one order of magnitude lower than is possible with the passive load modulation (PLM) used by contactless cards. ams AG www.ams.com 48 Electronic Engineering Times Europe November 2015 www.electronics-eetimes.com
