Renesas — RAxE1 MCU Fast Prototyping Boards

Renesas RAxE1 MCU Fast Prototyping Boards

Fast prototyping boards accelerate development with Arm Cortex-M23-based MCUs

Renesas has launched a series of fast prototyping boards which help users of its Arm Cortex-M23 core-based RAxE1 series of microcontrollers to accelerate product development.


The boards have a built-in emulator circuit equivalent to an E2 emulator Lite, to enable the user to write and debug programs without additional tools. Arduino Uno and two Pmod™ interfaces make it easy to add expansion boards to model system functionality in the end application. The boards provide through-hole access to all the MCU’s pins.


Sample software is available to demonstrate the functionality of the RAxE1 MCUs. The software also connects the board to wireless or sensor modules.


The RA2E1 series of microcontrollers features optimized processing operations and benefits from low-power process technology unique to Renesas, making them the industry’s most energy-efficient ultra low-power MCUs. They are ideal for battery-operated applications and other space-constrained systems requiring high performance and low energy consumption.


The RA4E1 series is supported by an open and flexible ecosystem, the flexible software package (FSP), and provides an excellent entry point into the RA Family of microcontrollers.


The high-performance RA6E1 MCUs are suitable for entry-level IoT applications requiring streamlined features and connectivity including Ethernet networking. The high performance of the RA6E1 MCUs is reflected in a 790.75 CoreMark® score, and 3.95 CoreMark/MHz.


The fast prototyping board for the RA2E1 MCUs is the RTK7FPA2E1S00001BE. It features an R7FA2E1A93CFM MCU, based on a Cortex-M23 core running at 48 MHz, with 128 kbytes of code Flash and 16 kbytes of SRAM.


The fast prototyping board for the RA4E1 MCUs is the RTK7FPA4E1S00001BE. It features an R7FA4E10D2CFM MCU, based on a Cortex-M23 core running at 100 MHz, with 512 kbytes of code Flash and 128 kbytes of SRAM.


The fast prototyping board for the RA6E1 MCUs is the RTK7FPA6E1S00001BE. It features an R7FA6E10F2CFP MCU, based on a Cortex-M23 core running at 100 MHz, with 1 Mbyte of code Flash and 256 kbytes of SRAM.
