TOKYO- Renesas Electronics has announced the expansion of its 32-bit RA family of microcontrollers (MCUs) with two new Groups. These are based on the Arm Cortex-M33 core with Arm TrustZone technology. The new 100-MHz RA4E2 Group and 200-MHz RA6E2 Group are optimized to provide best-in-class power efficiency without compromising performance. With 128 Kbyte and 256 Kbyte flash options and 40 Kbytes of SRAM, the new groups integrate abundant connectivity options such as on-chip CAN FD, USB, QSPI, SSI and I3C interfaces. Further, it offers an easy upgrade path to other members of the RA Family. They are ideal for applications requiring high performance in small packages such as sensing, gaming, wearables and appliances.
The RA4E2 and the RA6E2 are the most cost-effective members of the RA family with integrated CAN FD. They are available with small package options including a space saving 4 x 4 mm 36-pin BGA and a 5 x 5 mm 32-pin QFN. This is to satisfy the needs of cost-sensitive and space-constrained applications. In addition, the low power consumption of the new devices saves energy, enabling end products to contribute to a greener environment.
All RA devices are supported by the Renesas Flexible Software Package (FSP). It includes highly efficient drivers and middleware to ease the implementation of communications and improve functionality of peripherals. The FSP’s GUI simplifies and accelerates the development process. It enables flexible use of legacy code as well as easy compatibility and scalability with other RA family devices. Designers using FSP also have access to the full Arm ecosystem as well as Renesas’ extensive partner network. Thus, offering a wide range of tools that help speed time-to-market.
RA4E2 MCU Group
The RA4E2 Group includes five different options, spanning from 32-pin to 64-pin packages as small as 4 x 4mm, and 128kB of flash memory along with 40kB of SRAM. The RA4E2 devices offer excellent active power consumption, using 82 µA / MHz while executing from Flash at 100 MHz. They have an extended operating temperature range of -40/105°C. The RA4E2 Group is ideal for cost-sensitive applications and other systems requiring an optimal combination of performance, low power consumption and small package size.
