UFS 3.0 Embedded Flash to Support Full-Duplex 2.4GB/s Transfer Speeds

September 10th, 2017 3 comments

All my devices still rely on eMMC flash for storage, but premium smartphones, for example, make use of UFS 2.0/UFS 2.1 flash storage with performance similar to SSD, with Samsung UFS 2.0 storage achieving up to 850MB/s read speed, 260 MB/s write speed, and 50K/30K R/W IOPS. UFS 3.0 promises to roughly double the performance of UFS 2.0/2.1 with transfer rates of up to 2.4 GB/s, and separately, the UFS Card v2.0 standard should deliver UFS 2.1 performance on removable storage.

Several Chinese and Taiwanese websites, including CTimes and Benchlife, have reported that companies have started getting UFS 3.0 & UFS Card v2.0 licenses from JEDEC, and Phison is working on a controller to support both new standards, and scheduled to launch in 2018.

Premium smartphone SoC are only expect to support UFS 3.0 in 2019 and beyond, and hopefully by that time eMMC will have been replaced by UFS 2.0/2.1 in entry level and mid range devices. The outlook for UFS cards is less clear, as I’ve yet to see a product equipped with a UFS slot.

The first time I read the SoC supported 802.11p, I though it might be a typo, but it’s just another WiFi standard specifically designed for automotive applications operating in the 5.9GHz range as explained on Wikipedia:

IEEE 802.11p is an approved amendment to the IEEE 802.11 standard to add wireless access in vehicular environments (WAVE), a vehicular communication system. It defines enhancements to 802.11 (the basis of products marketed as Wi-Fi) required to support Intelligent Transportation Systems (ITS) applications. This includes data exchange between high-speed vehicles and between the vehicles and the roadside infrastructure, so called V2X communication, in the licensed ITS band of 5.9 GHz (5.85-5.925 GHz). IEEE 1609 is a higher layer standard based on the IEEE 802.11p.[1] It is also the base of a European standard for vehicular communication known as ETSI ITS-G5.

88W8987xA drivers are readily available for the Android, Linux and QNX drivers are available for 88W8987xA, and the family of SoC is sampling today, with mass production starting in Q4 2017.

Solar Powered CAREUD U800WF Monitoring System Checks Your Car’s Tires Pressure

April 4th, 2017 1 comment

Every few months, we inflate (or deflate) our car tires at the gas station to match the pressures for front and rear tires given by the manufacturer. But if you want to make sure the pressures are always at their optimal levels, or close to it CAREUD U800WF pressure monitoring system might be a useful little gadget.

The monitor that you can place on your dashboard comes with the following specifications:

  • Display showing pressure with +/- 1.5 PSI accuracy and temperature with +/- 3 °C accuracy for all four tires; data updated every 3 seconds.
  • Connectivity – 433.92 MHz RF
  • Power Supply
    • Solar Panel
    • 5V via micro USB port
    • 900 mAh Li-ion Battery
  • Temperature Range – Storage: -30 to 85 °C; operating: -20 to 80 °C
  • IP Rating – IP5K4K (The “K” in the ingress protection rating means it complies with ISO 20653:2013 Road Vehicles-Degrees of protection)
  • Dimensions – 76 x 50 x 62 (depth) mm
  • Weight – 72 grams

The monitor is only part of the solution as the kit comes with four sensors to connect to your tires, four anti-theft screws, a sensor wrench, a spanner, a charging cable, as well as a user guide, an installation manual, and a warranty card.

The system will alert you by flashing icon and emitting a beep when the pressure is too high or too low, or when the temperature is too high (> 70 °C). It’s also capable of detecting air leakage, and report is the sensors’ battery level is low.

I first found CAREUD U800WF on GeekBuying where it is sold for $79.99 shipped, but you’ll also find it on eBay and Amazon US. I could not find that exact model on Aliexpress, but if you look for CAREUD, you’ll find other models, including some specifically designed for trucks with 6 wheels.
