Arduino Nicla Sense Env module features temperature, humidity, and gas sensors from Renesas

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over three years ago (2021). The implementation of the new module is quite different since the ME module relies on Nordic Semi nRF52832 Cortex-M4 microcontroller and Bosch SensorTech motion and environmental sensor, but the new Nicla Sense Env module is made of parts from Renesas namely the RA2E1 Cortex-M23 microcontroller, the HS4001 humidity and temperature sensor, the ZMOD4410 gas sensor for TVOC and indoor air quality, and the ZMOD4510 gas sensor for NO2, O3, and outdoor air quality. Arduino Nicla Sense Env (ABX00089) specifications: MCU – Renesas RA2E1 Arm Cortex-M23 entry-line microcontroller (not accessible or programmable by the user) CPU core – Arm Cortex-M23 core up to 48 MHz Memory – 16KB SRAM Storage – 128KB flash Sensors […]

Renesas RRH62000 multi-sensor indoor air quality monitoring module features particle, VOC, and gas sensors

Renesas Electronics has introduced the RRH62000, a compact multi-sensor module for indoor air quality monitoring. It integrates particle detection, VOC, and gas sensing with an onboard Renesas MCU for sensor management. The module is designed for use in air purifiers, smoke detectors, HVAC systems, weather stations, and smart home devices. The RRH62000 is an integrated sensor module that measures key air quality parameters, including particulate matter (PM1, PM2.5, PM10), total volatile organic compounds (TVOC), Indoor Air Quality Index (IAQ), estimated carbon dioxide (eCO2), temperature (T), and relative humidity (RH). These measurements are combined into a single package, with digital outputs available for each sensor, enabling simultaneous measurement. The module features a six-pin connector for easy plug-and-play integration. The RRH62000 is available with the RRH62000-EVK evaluation kit, which simplifies the testing of the integrated sensor module. The module measures critical air quality parameters and connects to a Windows PC via USB. […]

Renesas SLG7EVBFORGE FPGA dev board is built around ForgeFPGA SLG47910V low-density FPGA

Renesas SLG7EVBFORGE 1K LUT ForgeFPGA Evaluation Board

Renesas SLG7EVBFORGE FPGA dev board, built around SLG47910V is Renesas’ first low-density FPGA in the ForgeFPGA family. The FPGA includes 1120 LUTs, 1120 flip-flops, 5kb of distributed memory, 32kb of block RAM, and a 50 MHz on-chip oscillator with a phase-locked loop (PLL). With robust features, low power consumption, and affordable pricing this FPGA can be used in applications in sensor data aggregation, consumer electronics, and portable computing devices. The SLG47910V FPGA gets connected to a ZIF socket to the development board, this design choice puts out a clear sign that upcoming Forge family FPGAs will support this dev board. Additionally, it features Pmod connectors and configurable power sources. The dev board can be programmed via OTP Non-Volatile Memory or SPI interface and additional features get managed through Renesas’ Go Configure Software Hub. Previously we have written about similar low-power low-cost FPGA boards like the Sipeed Tang Mega 138K, the […]

Renesas RA0 Cortex-M23 MCU series target power and cost-sensitive applications

Renesas has announced the new low-power RA0 microcontroller series based on the power-efficient Arm Cortex-M23 core and the entry-level RA0E1 Group in the series. According to Renesas, the RA0 microcontrollers offer the “industry’s lowest overall power consumption for general-purpose 32-bit MCUs.” With a current consumption of 84.3 μA/MHz in active mode and only 0.82 mA in sleep mode, these microcontrollers are built to provide ultra-low power consumption. They also offer a Software Standby mode where the CPU, peripheral functions, and internal oscillators cease to operate. This mode reduces power consumption further by 99% down to 0.20 µA. They also come with a high-precision, High-speed On-Chip Oscillator (HOCO) for fast wake-up. The Cortex-M23 core is based on the Armv8-M instruction set and offers a maximum clock frequency of 32 MHz, with up to 64KB of code flash memory and 12KB SRAM for storing application code and data. This feature set makes […]

R9A02G021 is the first microcontroller with Renesas 32-bit RISC-V CPU core design

Renesas R9A02G021 is the first MCU group to use the company’s in-house designed 32-bit RISC-V CPU core with 3.27 CoreMark/MHz, RV32I base plus M/A/C/B extensions, and features such as a stack monitor register, a dynamic branch prediction unit, and a JTAG debug interface. Renesas has been making RISC-V chips at least since 2022 with the likes of RZ/Five 64-bit microprocessor and R9A06G150 32-bit voice control ASSP. All those were based on Andes RISC-V cores, but since the company has now designed its own 32-bit core, future Renesas 32-bit RISC-V microcontrollers are all likely to feature the in-house core, starting with the R9A02G021 general-purpose MCU group. Renesas R9A02G021 key features and specifications: RISC-V Core Renesas RISC-V instruction-set architecture (RV32I + MACB + Ziscr, Control and Status Register (CSR) instructions + RISC-V Zifencei Instruction-Fetch Fence) Maximum operating frequency – 48 MHz Debug and Trace – RISC-V External Debug Support cJTAG Debug Port […]
