Renesas Electronics has expanded the RA4 series of microcontrollers with a new group of 32-bit microcontrollers, which has been designated RA4M3. These microcontrollers use the Arm Cortex-M33 core, which operates at a frequency of up to 100 MHz.
According to Renesas, offering industry-leading performance, Arm TrustZone and Renesas Secure Crypto Engine technologies, as well as an advanced memory subsystem, RA4M3 microcontrollers simplify the development of secure and secure industrial electronics and IoT peripherals with low power consumption.
In active mode, the power consumption is 119 ua / MHz. In standby mode, the current consumption does not exceed 1.6 ma, and 30 microseconds are enough for the microcontroller to wake up from standby mode. The microcontroller configuration includes 1 MB of flash memory, 128 KB of RAM, 8 KB of data flash memory, and 1 KB of standby SRAM. For memory-intensive applications, developers can combine the built-in memory of the microcontroller with external memory connected to the Quad-SPI interface and with an SD card to increase the volume. The ability to switch flash memory banks and work with it in the background allows you to perform firmware updates in the background. The presence of built-in interface blocks, including Quad SPI, SDHI, SSI, USB2. 0, SCI, SPI/I2C and a touch input unit, allows you to reduce the number of additional components, simplify the design of devices and reduce their cost.
microcontrollers are produced according to the 40-nanometer process technology. Depending on the model, LQFP housings with a number of contacts from 64 to 144 are used.
Earlier this month , Renesas Electronics released 20 cost-effective microcontrollers for the Internet of Things.
