Renesas Electronics RA2 Family Arm® Cortex® Microcontrollers
Renesas Electronics RA2 Family Arm® Cortex® Microcontrollers are entry-level 32-bit MCUs offering excellent cost, performance, and ultra-low power consumption as part of the Renesas RA Family. The RA2 MCUs support up to 48MHz of CPU performance using an Arm Cortex-M23 core with up to 256KB of embedded flash memory. The RA2 has a wide single voltage supply range from 1.6V to 5.5V.
The Renesas Electronics RA2 Family Arm Cortex Microcontrollers deliver cutting-edge peripherals like high accuracy analog and capacitive touch sensing. These peripherals make the RA2 Series most suitable for system control or user interface applications such as healthcare devices, home appliances, office equipment, and measuring equipment.
Features
- Large product lineup is starting with 25pin up to 100pin and Flash memory size starting from 32KB up to 128KB, including some very small package options, including QFN, LGA, BGA, and smallest WLCSP
- Ultra-low power consumption delivering an operating current of 64μA/MHz and software standby current of 250nA with less than 5µs fast wakeup
