Diodes Inc. New PI7C1401AZFEX Quad Port Expander

The PI7C1401 is an I²Cbus/SPI quad port expander, it is specifically designed to manage common port types such as SFP+ and QSFP+.
The PI7C1401 provides an I²Cbus/SPI interface, an interrupt output to host and four I²C interfaces, general purpose pins for low-speed control signals to the modules.
The PI7C1401 can be used in a wide range of applications such as networking, telecom, storage/data center, and embedded systems. The typical usage for this device is high volume applications requiring an "expander" to aggregate all low-speed control and I²C signals across four ports and presents a single I²C or SPI interface to host.
Multiple PI7C1401s can be used in high-port-count applications with one I²C or SPI to host. The system BOM cost can be cut by using smaller IO count control device (FPGAs, CPLDs, MCUs) and by reducing routing layer congestion.

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...
