Renesas releases the DA14592, a new dual-core Cortex-M33/M0+ BLE chip with integrated flash

DA14592 chip block diagram

The DA14592 System-on-Chip (Soc) is Renesas’ “lowest power consumption and smallest, multi-core Bluetooth LE device.” According to the company, this chip’s design was achieved by making careful tradeoffs between on-chip memory and die size. The chip offers an ultra-low power mode that uses only 2.3mA when transmitting radio signals at 0dBm and consumes 1.2mA to receive radio signals. It also supports a hibernation mode that uses about 90nA and can extend the operating life of battery-powered products. The active mode is best for processing-intensive products and uses 34µA for every MHz of CPU clock. Projected key applications for the DA14592 chip include crowd-sourced location (CSL) tracking as used in Apple’s Airtags, remote control units, human interface devices, asset tracking, IoT end nodes, data logging, connected health, and activity tracking. Renesas DA14592 specifications: CPU cores: Cortex-M33F running at up to 64MHz as application core Cortex-M0+ at 64MHz as configurable MAC Memory: […]

Renesas RZ/G3S is a 64-bit Arm Cortex-A55/M33 microprocessor with low power consumption and enhanced peripherals

rzg3s lineup en

Renesas RZ/G3S 64-bit Arm Cortex-A55 microprocessor (MPU) designed for IoT edge and gateway devices consumes as little as 10µW in standby mode thanks to its Cortex-M33 core(s) and features a PCIe interface for high-speed data transfers with 5G wireless modules. A single-core ARM Cortex-A55 CPU powers the RZ/G3s and can distribute workloads to two sub-CPUs, boosting efficiency in task handling and resulting in fewer components and a smaller system size. The Cortex-A55 core operates at 1.1GHz and is designed to improve power efficiency and performance over its predecessor, the Cortex-A53. The RZ/G3S isn’t Renasas’ first Cortex-A55 product as they have previously released the RZ/A3UL and the RZ/G2L, both powered by the same Cortex-A55 CPU. Additionally, Renesas launched the 64-bit RISC-V RZ/Five processor late last year. The RZ/G3S boasts high-speed interfaces such as PCIe and GbE, a better standby mode, and improved security features which make it suitable for IoT applications […]

Renesas’ first 32-bit RISC-V CPU core delivers up to 3.27 CoreMark/MHz

Renesas has recently announced its first homegrown 32-bit RISC-V CPU core based on open-standard instruction set architecture (ISA).

Renesas has recently announced its first homegrown 32-bit RISC-V CPU core based on the open-standard instruction set architecture (ISA). This CPU core is compatible with Renesas’ e2 studio IDE and supports other third-party IDEs for RISC-V MCUs. According to Renesas, the CPU achieved a remarkable 3.27 CoreMark/MHz performance outperforming similar RISC-V architectures in this category. RISC-V, an open ISA, is rapidly gaining popularity in the semiconductor industry. Many MCU providers have formed joint investment alliances to expedite their RISC-V product development. Previously, Renesas released two CPUs developed by Andes Technology Corp: the R9A02G020, an ASSP EASY MCU for Motor Control, and the R9A06G150, an ASSP EASY MCU for Voice HMI, both based on RISC-V. Additionally, they have introduced the RZ/Five, a Linux-capable 64-bit RISC-V microprocessor family, and RH850/U2B, an automotive System on Chip (SoC).  However, with the release of their new CPU, Renesas independently enters the RISC-V market, highlighting their […]
