STM New PM8804TR and PM8805TR 100W Power-over-Ethernet, PoE- PD

A new chipset from STMicroelectronics lets users quickly build reliable and space-efficient Powered Devices (PDs) to take advantage of the latest IEEE 802.3bt Power-over-Ethernet (PoE) specification
The PM8804 and PM8805 provide the PoE-converter circuitry for PDs up to class-8, which defines a usable power budget of 71 Watts. The chipset saves space, enhances reliability, and cuts time to market for next-generation connectivity equipment including 5G “small cells,” WLAN access points, switches, and routers. ST’s new PoE chipset also targets smart-building and smart-office applications such as IP cameras, access-control systems, display panels, lighting, curtain or shutter controllers, video-call systems, IP phones, and tabletop consoles.

 PM8804TR: PWM peak current mode controller for PoE and telecom systems
PM8805TR: IEEE 802.3bt PoE-PD interface with embedded dual active bridge

Microchip New SAMV71Q21RT, SAMRH71 Radiation-Tolerant and Radiation-Hardened Arm® MCU

Microchip introduced the space industry’s first Arm®-based microcontrollers (MCUs) that combine the low-cost and large ecosystem benefits of Commercial Off-the-Shelf (COTS) technology with space-qualified versions that have scalable levels of radiation performance. Based on the automotive-qualified SAMV71, the SAMV71Q21RT radiation-tolerant and SAMRH71 radiation-hardened MCUs implement the widely deployed Arm® Cortex®-M7 System on Chip (SoC), enabling more integration, cost reduction and higher performance in space systems. SAMV71Q21RT is the radiation tolerant version of the popular Microchip SAMV71Q21. This space-qualified version of the product adds:  Ceramic & hermetic package, extended temperature range -40C to 125C, extended qualification flow according to QML-V or QML-Q space grade flow.  Radiation performance for the SAMV71Q21RT:  SEL LET > 60 MeV.cm2/mg (at 125C), and TID up to 20 Krad (Si). SAMRH71 is the Radiation-Hardened-By-Design (RHBD) version of...
