Overview
R7FA2E3053CNE#BA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 32-KB code flash, 16-KB SRAM, 12-bit ADC with 10 input channels, and integrated safety functions including SRAM parity, CAC, CRC, and IWDT. It targets battery-powered industrial sensors and smart metering endpoints requiring functional safety compliance and extended temperature operation.
For engineers reviewing the R7FA2E3053CNE#BA0 datasheet, R7FA2E3053CNE#BA0 pinout, R7FA2E3053CNE#BA0 application, or R7FA2E3053CNE#BA0 equivalent, key selection criteria include its -40°C to +105°C industrial-grade HWQFN-48 package, 1.6–5.5 V wide supply range, dual watchdog timers (WDT/IWDT), and hardware-accelerated data integrity features (CRC, DOC, CAC) for IEC 61508/UL 60730-classified systems.
Technical Context
The R7FA2E3053CNE#BA0 implements the Armv8-M architecture with Memory Protection Unit (MPU) supporting 8 regions, enabling secure partitioning of firmware and data. Its clock system integrates HOCO (48 MHz), SOSC (32.768 kHz), and IWDT-dedicated 15 kHz oscillator, with Clock Frequency Accuracy Measurement Circuit (CAC) for real-time oscillator calibration.
System-level safety is enforced via independent watchdog timer (IWDT) with dedicated clock source, SRAM parity error detection, register write protection (PRCR), illegal memory access monitoring, and ADC self-diagnosis - all aligned with IEC 61508 SIL2 and UL 60730 Class B requirements. The Event Link Controller (ELC) enables autonomous peripheral triggering without CPU intervention.
