It includes 2 KB on-chip EEPROM and operates from -40°C to 125°C with a 1.6 V to 5.5 V supply. Peripherals include DMA, LVD, POR, PWM, and WDT, with connectivity covering I²C, SPI, and UART/USART. An 8-channel 12-bit SAR ADC handles analog inputs. The MCU comes in a 24-HWQFN exposed-pad package (4x4 mm), with 20 general-purpose I/O lines. ## Memory footprint — sizing for the firmware load 16 KB Flash and 8 KB RAM place this MCU in the small-footprint tier. It is sized for a single control loop, a sensor-fusion algorithm, or a UART-to-I²C bridge. The 2 KB EEPROM stores calibration coefficients or fault logs.","metaTitle":"Renesas R7FA2E2A34CNK#AA1 RA2E2 MCU, 48MHz ARM Cortex-M23","metaDescription":"Renesas RA2E2 32-bit MCU, ARM Cortex-M23 at 48MHz, 16KB Flash, 8KB RAM, 2KB EEPROM, 24-HWQFN, -40 to 125°C.
