It has 32 KB Flash, 16 KB RAM, and 4 KB EEPROM on-chip. ## Industrial temperature and peripheral set Rated for -40°C to 105°C, this MCU is at home in motor drives, outdoor telecom gear, and factory automation panels where the ambient can climb. The 10-channel 12-bit SAR ADC handles analog inputs from thermistors, pressure transducers, or current shunts without an external converter. On the security side, the hardware AES accelerator and true random number generator (TRNG) save code space for encrypted communication — a plus for IoT edge nodes that need to authenticate firmware updates. ## Sourcing and lifecycle Renesas lists this part as Active, and it is ROHS3 compliant. For dual-sourcing or a drop-in alternate, the R7FA2E1A52DNH#AA0 shares the same core, memory, and peripherals but is rated to 85°C instead of 105°C — check your ambient before swapping.","metaTitle":"R7FA2E1A53CNH#AA0 RA2E1 ARM Cortex-M23 MCU, 48 MHz","metaDescription":"R7FA2E1A53CNH#AA0 Renesas RA2E1 32-bit MCU, ARM Cortex-M23 at 48 MHz, 32 KB Flash, 16 KB RAM, 4 KB EEPROM, -40 to 105°C, 32-HWQFN.
