Duesseldorf, Germany TDK Electronics has introduced two chip ceramic resonators targeting the home appliance and industrial sectors. The CCR-MXC8 and CCR-MUC8 are designed for low frequencies, and offer high reliability even in tough environmental conditions. The CCR series are thin-type ceramic resonators, which use fundamental thickness-share mode vibration. Two capacitors are built in the baseboard, thus simplifying the oscillating circuit. This helps to achieve stable oscillation across a broad temperature range. The layout pattern on the CCR series is compatible with other major suppliers. The resonators are suitable as the clock source for microcontrollers, ADCs/DACs and DSPs in home appliance devices such as washers, cookers and refrigerators as well as in industrial machine and process systems. The CCR-MUC8 comes in the 4020 size (4.0 x 2.0 mm) and caters for low frequency applications in the range 4-7.99 MHz. The CCR-MXC8 is offered in the smaller size of 3213 (3.2 x 1.3 mm), available in the frequency range 8-11 MHz. Both parts are developed using TDK's expertise with original piezoelectric materials and packaging. The components are fully RoHS compliant.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
