Nordic Semiconductor ASA has expanded its existing 2.4GHz RF and ANT™ product line-ups with a new set of miniaturized, wafer-level chip scale package (WLCSP) options designed to meet the space-constrained needs of both existing and emerging sports, fitness, and health applications such as wireless watches, bike computers, sensors, hearing aids and other devices designed to be worn on or near the body.
nRF24AP2-1CHC32 and nRF24AP2-8CHC32: 400µm pitch (regular array) 32-ball BGAs with a thickness of 0.5mm and a flat footprint area of 2.6 x 2.7mm (7mm2).
nRF24LE1 WLCSP option (Flash or OTP): 400µm (regular array) 32-ball pitch BGA measuring 2.7 x 2.7 (7.3mm2) in footprint area for the Flash version and 2.6 x 2.7 (7mm2) for the OTP version. Both devices are 0.5mm in thickness.
Sampling in Q1 2011 and available for volume orders in Q2 2011 will be the nRF24AP2 WLCSP (1- and 8-channel) and nRF24LE1 WLCSP (Flash or OTP) options.
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.
