Renesas Electronics RA4E2 Microcontrollers
Renesas Electronics RA4E2 Microcontrollers deliver optimized performance with a 100MHz Arm® Cortex®-M33 core, 128KB code flash memory, and 40KB SRAM. Renesas Electronics RA4E2 features peripherals like a general PWM timer, 12-bit A/D converter, 12-bit DAC, USB FS device, SCI, SPI, I3C, SSI, CANFD, and HDMI-CEC. The device is ideal for low-memory, small-package, low-pin count applications and ensures high-speed performance. And with the support of the Flexible Software Package (FSP), the RA4E2 group makes it easy to design applications.
The RA4E2 provides an entry point to the wider RA family due to its well-balanced performance, advanced peripheral functions, and scalability.
