Murata claims world’s smallest 32.768 kHz MEMS resonator



Murata claims to have developed the world’s smallest 32.768 kHz MEMS resonator (the WMRAG series).

Based on miniature MEMS technology, the new resonators exhibit stable frequency characteristics with a temperature drift of <160 ppm across their operating range of -30 to 85 °C.
Initial frequency accuracy is ±20 ppm which is at the level expected of a more sophisticated (and expensive) crystal resonator.

An in-built 6.9pf capacitor reduces the components necessary for the circuit that generates the reference clock signal, thereby reducing the space required as well as giving designers more flexibility in designing their solution.
Measuring 0.9 x 0.6 x 0.3 mm (W x L x H), the new MEMS resonator is over 50 % smaller than a conventional 32.768 kHz crystal resonator that measures 1.2 x 1.0 x 0.3 mm.
Available in silicon-based wafer-level chip scale packaging (WL-CSP), the device can be integrated into an IC made of a homogeneous semiconductor material.
The resonator generates stable reference clock signals by reducing the IC gain based on a low ESR value of 75 kΩ.
Mass production of the device is scheduled to begin in December 2018.

AXI

When part of a team, your group can become more capable than a single individual, but only if your team can work together and communicate effectively. Having members of a group talk over each other leads to nothing but a cacophony, and nothing gets done. For this reason protocols need to be established, such as letting others speak without interruption, or facing those you are addressing. The same is necessary with electronics, especially with system on chip (SoC) designs.

Introducing the AXI ProtocolThe protocol used by many SoC designers today is AXI, or Advanced eXtensible Interface, and is part of the Arm Advanced Microcontroller Bus Architecture (AMBA) specification. It is especially prevalent in Xilinx’s Zynq devices, providing the interface between the processing system and programmable logic sections of the chip.My first introduction with the interface was in a tutorial I was following that was to be implemented on Aldec’s own development board based off the Zynq XC7Z030, theT…

VECTOR (The good Robot)

vector is not a toy but rather a joyful,smart home robot..
A helpful character. Vector is happiest when he’s helping. He’s eager to accommodate your requests and answer your questions. He isn’t a fully grown robot butler capable of doing your taxes, buttering your bread, or writing a position paper on the future of robot/human relationships, but he’s a helpful little guy who puts his whole self into helping you out. That’s what we call Characterful Utility. TIMER Vector will set a timer and share in your joy when your muffins come out perfect, or when your laundry is finally done.

BLACKJACK He’s a robot. He’s a friend. He’s a blackjack dealer.


WEATHER Ask him any city’s weather and he’ll show you



TAKE A PHOTO Ask him to take a photo, say cheese, and wait while he snaps it. Can we call this a robot selfie?
