Renesas expands options with Andes-based RISC-V MPU
www.embedded.com, Mar. 07, 2022 –
Renesas Electronics Corporation said it has expanded the options for developers using its general-purpose microprocessor units (MPUs), with a new MPU built around a 64-bit RISC-V CPU core from Andes Technology.
Its new RZ/Five general-purpose MPUs employs the Andes AX45MP, based on the RISC-V CPU instruction set architecture (ISA). The RZ-Five augments Renesas' previously available Arm CPU core–based MPUs, providing customers with more options and flexibility in the product development process.
The new RZ/Five is optimized to provide the performance and peripheral functions required in IoT endpoint devices, such as gateways for solar inverters or home security systems, to collect sensor data and connect to servers or to the cloud. Its maximum operating frequency is 1 GHz. Peripheral functions include support for multiple interfaces, such as two Gigabit Ethernet channels, two USB 2.0 channels, and two CAN channels, as well as dual A/D converter modules. Support is also provided for connecting external DDR memory with error checking and correction (ECC) and security functions.
