HPMicro HPM64G0 – A 1 GHz RISC-V microcontroller

Yesterday, I ended up on the HPMicro website showing the illustration above about a 1 GHz MCU called HPM64G0. It looked interesting enough so I clicked on the link to a page with some documentation for the company’s HPM6700/6400 microcontrollers. But in typical Chinese fashion, I was asked for a mobile phone number to download the documents. No luck this time since a Chinese mobile phone number is required. If anybody can set up a mirror on Mega or other websites easily accessible outside of China that would be appreciated. But eventually, I found an article in Chinese on EETrend where we can learn more about the HPM64G0 which happens to be a 1GHz microcontroller based on the RISC-V architecture. We already had one of those for Arm with the NXP i.MX RT1170, but I had yet to see any RISC-V microcontrollers clocked at such a high frequency. HPMicro HPM64G0 […]

LILYGO T-RSC3 ESP32-C3 board features isolated RS232 & RS485 interfaces, 5 to 24V DC input

LILYGO T-RSC3 is a relatively compact ESP32-C3 board with WiFi 4 and Bluetooth LE 5.0 connectivity, support for RS232 and RS485 communication protocols through a DB9 connector and a terminal connector respectively, and a wide 5V to 24V DC power input. LILYGO had already made an ESP32 board with CAN Bus and RS485 interfaces called the T-CAN485, but without any isolation. The new T-RSC3 offers both RS232 and RS485 interfaces, but no CAN Bus, protected by isolated transceiver modules that should make it safer to use in industrial environments. LILYGO T-RSC3 board specifications: Wireless module – Espressif Systems ESP32-C3-MINI-1U module with ESP32-C3 RISC-V microcontroller @ 160 MHz with 400 KB SRAM, 2.4 GHz WiFi 4, Bluetooth 5.0 LE & Mesh, 4MB flash, and a u.FL antenna connector Industrial control interfaces RS232 via DB9 connector, RSM232MT5V isolated transceiver with 3000V isolation, 4.75~5.25V input, 5V/50mA output, baud rate from 1200 to 256,000 […]

Quiet, ultrathin AirJet solid state active cooling chips could replace fans

Frore Systems Airjet Mini and Airjet Pro are active cooling chips that are just 2.8mm thick and quietly suck cool air in from the top of the chip before pushing it out the sides with the aim to replace traditional fan-based solutions in ultrabooks, or be integrated into VR headsets and smartphones for improved cooling. Yesterday we saw that cameras could clean themselves with micro-vibrations, and it happens that processors can be cooled with vibrations too as the Airjet chips are comprised of tiny membranes that vibrate at ultrasonic frequencies to generate a flow of air that enters through inlet vents in the top and transformed into high-velocity pulsating jets exiting from one side of the chip. The AirJet module is actually not placed directly on the processor in ultrabooks but on copper pipes because it allows for thinner designs that way. The company says the AirJet Mini and Pro […]
