Renesas adds Arm Cortex-M330-based microcontroller to RA4 family

Entry-level microcontrollers expand Renesas Electronics’ 32-bit RA family of microcontrollers. The RA4E1 microcontrollers are the first entry-level devices in the series and are based on an Arm Cortex-M33 core.

The 100MHz RA4E1 group is claimed to have best in class power consumption and is designed to enable fast design cycles and easy upgrades to other RA family devices, which currently number over 150 parts, ranging from 48 to 200MHz.

The RA microcontrollers have a range of communications options and security options, including Arm TrustZone technology. All RA devices are supported by the Renesas Flexible Software Program (FSP) which includes drivers and middleware to implement communications and security. The FSP’s GUI simplifies and accelerates the development process, claims Renesas. It is also claimed to enable flexible use of legacy code and easy compatibility and scalability with other devices in the RA family. Designers using FSP also have access to the Arm ecosystem as well as Renesas’ extensive partner network.

The RA4E1 microcontrollers save system costs with on-chip high precision (±0.25 per cent) internal oscillator using FLL, GPIO, advanced analogue, low-voltage detection and internal reset function, says Renesas. They use just 60microA per MHz while executing from flash at 100MHz. Integrated flash memory options range from 256kbyte to 512kbyte and 128kbyte RAM. The microcontrollers integrate USB 2.0 Full-Speed Device, serial communication, CAN and QSPI. They are supplied in a choice of 48 to 64-pin packages and have a wide temperature range of -40 to +85 degrees C.

All the new RA4E1 MCUs are available today. The company also offers the FPB-RA4E1 fast prototype board with an on-chip debugger.
