Realtek RTL8126, RTL8157, and RTL8251B 5Gbps Ethernet solutions showcased at COMPUTEX 2023

I only upgraded my local network to 2.5 Gbps Ethernet last year, but 5 Gbps Ethernet is soon coming to the home as shown by Realtek at COMPUTEX 2023 with demonstrations of their RTL816, RTL8157, and RTL8251B 5GbE chips that were initially unveiled at CES 2022. The RTL8126-CG is a PCIe 3.0 x1 to 5GbE controller offered in a QFN56 8x8mm package that succeeds the RTL8125 chips, the RTL8157-CG is a USB 3.2 Gen2 to 5Gbps Ethernet controller in a 8x8mm QFN68 package providing an update the RTL8156(B)/(BG) 2.5GbE USB controllers, and the RTL8251B-CG is a single-port “PHYceiver” in a 8x8mm QFM56 package. All support 10/10/100/2500/5000 Mbps links and consumes under 1.5 watts, against 0.7W for 2.5 GbE networking. The same Cat5e cables can be used at the higher speed. The company did not just come with some slides to show and also showcased some test boards for each chip […]

ARIES v3.0 development board features India-made VEGA RISC-V processor

ARIES v3.0 is an Arduino-inspired development board with the made-in-India 100 MHz THEAJS32 ASIC with the VEGA ET1031 RISC-V microprocessor, 256KB of internal SRAM, and various I/Os. Not to be confused by the recent FIVEberry RISC-V SBC made by ARIES Embedded… We first wrote about VEGA RISC-V processors designed in India in February 2022, and at the time, the government worked on five RISC-V processor designs ranging from a single-core 32-bit RISC-V microcontroller-class processor to a Linux-capable quad-core 64-bit out-of-order processor, with the entry-level THEJAS32 and THEJAS64 SoCs based on respectively VEGA ET1031 and VEGA AS1061 cores running on an ARTY A7 FPGA board. But good progress has been made since then, and they have tapped out the THEJAS32 processor and manufactured some development boards such as the ARIES v3.0. ARIES v3.0 development board specifications: MCU – THEJAS32 VEGA ET1031 32-bit 3-stage in-order RISC-V ( RV32IM) microcontroller @ 100 MHz […]
