Product details
Overview
R7FA0E1053CNH#AA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 32 MHz, featuring 32-KB code flash, 12-KB SRAM, a 12-bit ADC with 8 input channels, and integrated safety features including SRAM parity, CRC, and Independent Watchdog Timer (IWDT). It targets battery-powered industrial sensors and smart metering endpoints requiring robust operation across -40°C to +105°C.
For engineers reviewing the R7FA0E1053CNH#AA0 datasheet, R7FA0E1053CNH#AA0 pinout, R7FA0E1053CNH#AA0 application, or R7FA0E1053CNH#AA0 equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and two validated alternative parts for design flexibility in cost-sensitive, low-power embedded systems.
Technical Context
The R7FA0E1053CNH#AA0 implements the Armv8-M architecture with TrustZone®-enabled security extensions and supports debug via SW-DP with CoreSight MTB-M23 trace. Its clock system integrates HOCO (24/32 MHz), MOCO (4 MHz), LOCO (32.768 kHz), and SOSC (32.768 kHz) with trimming support for all on-chip oscillators.
It features a Serial Array Unit (SAU) delivering 2 simplified SPI, 2 simplified I²C, and 2 UART interfaces - plus dedicated UARTA and IICA modules - alongside a 32-pin HWQFN package with 26 GPIOs, 2 of which are 5-V tolerant, and full support for Event Link Controller (ELC) and Data Transfer Controller (DTC) for CPU-offload peripheral coordination.
