The 64 KB on-chip flash (64K x 8) and 16 KB SRAM (16K x 8) leave room for a modest RTOS, a communication stack, and a sensor-fusion loop — but the 4 KB EEPROM (4K x 8) is the standout for storing calibration constants or boot-config parameters without wearing the main flash. ## Peripheral set and signal chain The part integrates DMA, LVD, POR, PWM, and a WDT — the usual complement for a standalone controller — plus a 13-channel 12-bit SAR ADC that samples at a rate determined by the external oscillator. The 40 I/O lines in the 48-LFQFP (7x7 mm) package give headroom for a parallel LCD interface or a keypad matrix alongside the serial peripherals — useful when the BOM budget doesn't stretch to a larger package. No AEC-Q100 grade is cited, so this is not qualified for under-hood automotive use. The tray packaging is the standard delivery format for this MCU; moisture sensitivity level should be verified from the latest Renesas packing label before reflow, especially if the tray has been opened.","metaTitle":"R7FA2E1A72DFL#AA0 Renesas RA2E1 MCU, 48MHz, 64KB Flash","metaDescription":"R7FA2E1A72DFL#AA0 Renesas RA2E1 32-bit ARM Cortex-M23 MCU, 48MHz, 64KB Flash, 16KB RAM, 4KB EEPROM, 40 I/O, 48-LFQFP.
