Product details

The Renesas R7FA2E1A52DFL#AA0 is a 32-bit ARM Cortex-M23 single-core MCU from the RA2E1 series, clocked at 48 MHz. It carries 32 KB of Flash program memory, 16 KB of RAM, and 4 KB of EEPROM.

Memory sizing and the firmware budget

32 KB Flash is the entry-level tier for the RA2E1 family — fine for a sensor hub, a keypad controller, or a simple motor-commutation routine. If your firmware needs a full RTOS plus a TCP/IP stack, you will bump into the ceiling. The 4 KB EEPROM is a separate block, not emulated in Flash, so you can store calibration constants or fault logs without wearing the main program memory.

On-chip peripherals include DMA, LVD, POR, PWM, and WDT. No CAN or USB, so if you need a fieldbus gateway, look at the RA2L1 sibling with CAN.

Renesas lists the R7FA2E1A52DFL#AA0 as Active and ROHS3 compliant. No NRND or EOL notice. The RA2E1 series is current-production.

Frequently asked questions

Is R7FA2E1A52DFL#AA0 obsolete?

No — Renesas lists this part as Active, with no end-of-life notice. It is a current-production device suitable for new designs.

Is R7FA2E1A52DFL#AA0 RoHS compliant?

Yes, it is ROHS3 compliant per Renesas.

What is the direct equivalent of R7FA2E1A52DFL#AA0?

The closest pin-compatible alternate is the R7FA2E1A52DNH#AA0, which shares the same Cortex-M23 core, 48 MHz clock, 32 KB Flash, and 16 KB RAM, but in a 32-pin package with 23 I/O. For a drop-in replacement with the same 48-LQFP footprint, there is no exact second source — the RA2E1 series is single-sourced by Renesas.
