ST ST64UWB Cortex-M85 SoC with IEEE 802.15.4z/802.15.4ab UWB Standards and Radar Sensing

STMicroelectronics ST64UWB UWB solution for Automotive Consumer and Industrial Applications

STMicroelectronics ST64UWB Arm Cortex-M85 ultra-wideband (UWB) SoC family supports both the current IEEE 802.15.4z and the upcoming IEEE 802.15.4ab UWB standards for longer-range, more reliable positioning and secure proximity-based interactions. It mainly targets digital car keys, hands-free access, and smart-device detection. The family includes the ST64UWB-A100 (automotive entry), ST64UWB-A500 (automotive premium), and ST64UWB-C100 (industrial/smart home), all built on an 18 nm FD-SOI process that improves the RF link budget by ~3 dB, yielding roughly 50% additional range beyond what IEEE 802.15.4ab alone provides. The automotive-focused A-series offers ASIL-A(B) safety support, while the ST64UWB-C100 targets consumer and commercial applications. ST64UWB family specifications: MCU Core 32-bit Arm Cortex-M85 CPU with DP-FPU, MVE, and ETM Frequency Up to 100 MHz (ST64UWB-C100, ST64UWB-A100) Up to 256 MHz (ST64UWB-A500) Memory/Storage Integrated PCM Memory SRAM and Back-up SRAM Wireless Connectivity Ultra-wideband (UWB) Radio IEEE 802.15.4z-2020 and IEEE 802.15.4ab support UWB channels 5, 6, 8, 9, 10, […]

The Original AirTag Is at Its Lowest Price Ever

Despite the fact Apple released a new AirTag in January, the first-generation AirTag is still a top-notch tracker if you’re embedded in Apple’s ecosystem. And right now, it’s on sale for $13.91 ($15.09 off) at Walmart, which marks a new low price.  If you’re an iPhone owner, the original AirTag still delivers a level of […]

Apple to Lower App Store Commission Fees in China Starting March 15

Apple has declared a major modification to its App Store commission rates in China, commencing March 15. This move follows conversations with Chinese regulatory bodies.

Beginning on the indicated date, the commission rate for standard Apple In-App Purchase and paid app transactions will be lowered from 30% to 25%. Moreover, the commission rate for qualifying transactions under the App Store Small Business Program and Mini Apps Partner Program, along with auto-renewals of Apple In-App Purchase subscriptions after the initial year, will be reduced from 15% to 12%.

Apple has underlined that developers are not required to sign updated terms by March 15 to take advantage of these new commission rates. The company is committed to maintaining a fair and transparent app ecosystem in China, ensuring that its rates are competitive with those in other markets.

For more information, Apple has released a complete blog post detailing these updates.
