Core and memory budget for a sensor endpoint
The R7FA2E1A72DFJ#AA0 is a Renesas RA2E1 series microcontroller built around a 32-bit ARM Cortex-M23 core running at 48 MHz.
Peripheral set and GPIO count
23 general-purpose I/O pins are available in the 32-LQFP package. On-chip peripherals include a 10-channel 12-bit SAR ADC, capacitive touch sensing, AES acceleration, a temperature sensor, a true random number generator, and a DMA controller. Connectivity covers I²C, SPI, UART/USART, and SmartCard interfaces.
Package and board-fit
It comes in a 32-lead LQFP with a 7x7 mm body and 0.80 mm pitch — hand-solderable in rework and compatible with standard 2-layer PCB fan-out. The supplier device package is 32-LQFP (7x7). Mounting is surface-mount only.
The part carries an Active lifecycle status from Renesas — no NRND or EOL risk for new designs. It is RoHS3 compliant.
