ESP32-C5 beta board features 2.4GHz and 5GHz SMA antenna connectors, two USB-C ports

ESP32-C5 test board

Espressif ESP32-C5 microcontroller was announced in June 2022 as the first dual-band WiFi 6 IoT chip from the company. It’s been quiet since then, but things are about to change as the ESP32-C5 beta board’s documentation has very recently been released. The ESP32-C5 was initially announced as a dual-band WiFI 6 and Bluetooth 5.0 LE SoC, but the user manual for the beta board indicates that it also supports Zigbee 3.0 and Thread 1.3, so there’s an 802.15.4 in the wireless microcontroller. The ESP32-C5 board itself features two SMA connectors for 2.4 GHz and 5GHz antennas or test equipment, two USB-C  ports, two 12-pin GPIO header, Boot and Reset buttons, an RGB LED, and a 2-pin header for current measurements. ESP32-C5 beta board specifications: SoC – ESP32-C5-BETA3 CPU – Single-core 32-bit RISC-V processor @ up to 240 MHz Memory – 400KB SRAM on-chip Storage – 384KB of ROM on-chip, support […]

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

Renesas R9A02G021 RISC-V MCU

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 […]
