Product details
Overview
R7FA2E1A53CFL#BA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 32 MHz, featuring 64-KB code flash, 12-KB SRAM, 12-bit ADC with 10 input channels, and integrated safety features including SRAM parity check, CRC, and independent watchdog timer (IWDT). It targets battery-powered industrial sensors and smart metering endpoints requiring extended runtime and functional safety compliance.
For engineers reviewing the R7FA2E1A53CFL#BA0 datasheet, R7FA2E1A53CFL#BA0 pinout, R7FA2E1A53CFL#BA0 application, or R7FA2E1A53CFL#BA0 equivalent, key selection criteria include its 32-pin LQFP package, -40°C to +105°C operating range, 1.6–5.5 V supply voltage, LIN-capable UART, and hardware-accelerated safety mechanisms for IEC 61508 SIL-2 readiness.
Technical Context
The R7FA2E1A53CFL#BA0 implements Armv8-M architecture with TrustZone®-enabled secure execution environment, supporting secure boot and memory isolation. Its system-level safety architecture includes register write protection, illegal memory access detection, and ADC self-diagnosis-enabling diagnostic coverage for ASIL-B automotive subsystems and IEC 61508-compliant control loops.
Power management integrates five clock sources (HOCO/MOCO/LOCO/SOSC/MOSC), low-power modes with ELC-triggered peripheral wake-up, and DTC-assisted data movement-reducing CPU intervention in sensor data acquisition and real-time actuator control tasks.
Key Specifications
