Product details
Overview
R7FA2E1A93CFJ#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, a 12-bit ADC with 10 input channels, integrated temperature sensor, and safety features including SRAM parity, CRC, IWDT, and flash protection. It targets battery-powered industrial sensors and smart metering endpoints requiring extended runtime and functional safety compliance.
For engineers reviewing the R7FA2E1A93CFJ#BA0 datasheet, R7FA2E1A93CFJ#BA0 pinout, R7FA2E1A93CFJ#BA0 application, or R7FA2E1A93CFJ#BA0 equivalent, key selection criteria include its 32-pin LQFP package, -40°C to +105°C operating range, 1.6–5.5 V supply, SAU-based serial flexibility (SPI/I²C/UART/LIN), and hardware safety mechanisms for IEC 61508 SIL-2-aligned designs.
Technical Context
The R7FA2E1A93CFJ#BA0 implements the Armv8-M architecture with TrustZone®-enabled security extensions, supporting secure boot and isolated execution environments. Its memory subsystem includes 64-KB code flash with read protection, 1-KB data flash rated for 1 million program/erase cycles, and 12-KB parity-protected SRAM.
System-level timing is managed by multiple clock sources: HOCO (24/32 MHz), MOCO (4 MHz), LOCO (32.768 kHz), and external crystal support (1–20 MHz MOSC, 32.768 kHz SOSC). Peripheral coordination uses Event Link Controller (ELC) and Data Transfer Controller (DTC) to enable CPU-free data movement between timers, ADC, and communication interfaces.
