DongshanPI-D1s – An Allwinner D1s RISC-V development board designed to teach programming

The DongshanPI-D1s development board is comprised of a soldered-on Allwinner D1s RISC-V system-on-module board (SoM) and a carrier board with two 40-pin headers and a 2.0mm dedicated header. This development board is specifically designed to teach programming with a focus on the RISC-V architecture. The development board was designed by 100ask. They previously designed the Dongshan NeZha STU a development board based on the Allwinner D1. The main difference between the two is that 100ask did not include the Ethernet and HDMI interfaces on the DongshanPI-D1s board. The pinout of the headers is also slightly different because they opted to make the headers compatible with the widely used 40-pin GPIO from Raspberry Pi single board computers. DongshanPI-D1s preliminary specifications: D1s Core Lite SoC – Allwinner D1s single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with with 32 KB I-cache + 32 KB D-cache Memory – 64 MB DDR2 (SIP) […]

Qualcomm Snapdragon W5+ and W5 wearables platforms promise higher efficiency and performance

It’s been a while since Qualcomm released a new platform for wearables. More exactly, the Snapdragon 4100 platform was announced a little over two years ago, and now Qualcomm has just introduced the Snapdragon W5+ and W5 Gen 1 platforms with up to 50% longer battery, twice the performance, and 30 percent smaller size. Just like the Snapdragon 4100, the Snapdragon W5 comes with four Arm Cortex-A53 processor (SW5100), but is clocked at 1.7 GHz and manufactured with a 4nm process, while the always-on (AON) co-processor is upgraded from a Cortex-M0 chip to the QCC5100 Cortex-M55 chip manufactured with a 22nm process. Snapdragon W5+/W5 specifications: W5100 SoC CPU – Quad-core Cortex-A53 processor @ up to 1.7 GHz GPU – Qualcomm Adreno A702 @ up to 1 GHz with OpenGL ES 3.1 API support DSP – Qualcomm Hexagon DSP V66K System Memory – 16-bit LPDDR4 up to 2,133 MHz […]

Imagination unveils IMG RTXM-2200 32-bit RISC-V real-time “Catapult” CPU

Imagination IMG RTXM-2200 32-bit RISC-V real-time CPU core is the first member of the company’s Catapult family comprised of four distinct RISC-V families for dynamic microcontrollers, real-time embedded CPUs, high-performance application CPUs, and functionally safe automotive CPUs. The company says it’s a highly scalable real-time, deterministic, 32-bit embedded CPU, that is feature-rich and flexible in design for mainstream devices, but, excuse the pun, leaves most of the details to your imagination… The new core will mostly be used as a helper core (aka co-processor) in more complex SoCs for 5G modems, cellular base stations, networking solutions for data transfer, packet management, and storage controllers, but may also find its way into smart meters. In all fairness, we do have some limited technical details with L1 cache sizes up to 128KB, I/D TCM sizes up to 128KB, and PMA regions. The real-time core will also include optional features such as single-point […]

ESP32-C5 RISC-V IoT MCU supports dual-band WiFi 6, Bluetooth 5.0 LE

Espressif Systems ESP32-C5 is an upcoming wireless RISC-V microcontroller for IoT applications that supports dual-band (2.4 & 5.0 GHz) WiFi 6 connectivity as well as Bluetooth 5.0 LE. It is the first dual-band processor from Espressif, as while the Shanghai-based company previously announced the ESP32-C6 WiFi 6 and Bluetooth 5 LE RISC-V SoC last year, it only supports 2.4 GHz frequency. Note it’s not the first dual-band WiFi 6 IoT chip on the market as NXP introduced the IW612 Wi-Fi 6, Bluetooth 5.2, 802.15.4 tri-radio solution last January, but ESP32-C5 should target different use cases. ESP32-C5 preliminary specifications: CPU – Single-core 32-bit RISC-V processor @ up to 240 MHz Memory – 400KB SRAM on-chip Storage – 384KB of ROM on-chip, support for external flash Connectivity Dual-band 802.11ax WiFi 6 in the 2.4GHz and 5 GHz bands, with 802.11b/g/n WiFi 4 standard support for backward compatibility 20MHz bandwidth for the 802.11ax […]
