Product details

RA2E2 entry-level 32-bit MCU for sensor and control applications

The R7FA2E2A34CNK#AA1 is a 32-bit ARM Cortex-M23 MCU from the RA2E2 series, clocked at 48 MHz with 16 KB Flash and 8 KB SRAM. 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.

Frequently asked questions

Is R7FA2E2A34CNK#AA1 obsolete?

No. The lifecycle status is Active with no end-of-life announcement. It is current-production and ROHS3 compliant.

Is R7FA2E2A34CNK#AA1 compatible with 5V logic?

Yes. The supply voltage range of 1.6 V to 5.5 V means the MCU can operate from a 5 V rail and its I/O levels track Vcc. At 5 V supply, the logic thresholds are 5 V compatible.

What is the difference between RA2E2 and RA2A1 series?

The RA2A1 series is a higher-tier family with larger memory options, more peripherals (including USB and CAN), and a wider operating temperature range. The RA2E2 is the entry-level, cost-optimized series with smaller Flash/RAM and a reduced peripheral set, targeted at simple sensor and control applications.

What is R7FA2E2A34CNK#AA1's listed speed?

The core runs at 48 MHz, which is the maximum clock for the RA2E2 series Cortex-M23 implementation.
