Overview
R7FA2L1A93CFN#AA0 from Renesas is an ultra-low-power 48 MHz Arm® Cortex®-M23 microcontroller with 128 KB code flash, 32 KB SRAM, 12-bit ADC/DAC, Capacitive Touch Sensing Unit (CTSU2), and integrated CAN 2.0B interface - designed for battery-powered industrial HMI, smart sensors, and secure edge nodes operating from 1.6–5.5 V across –40°C to +85°C.
For engineers reviewing the R7FA2L1A93CFN#AA0 datasheet, R7FA2L1A93CFN#AA0 pinout, R7FA2L1A93CFN#AA0 application, or R7FA2L1A93CFN#AA0 equivalent, this MCU delivers verified low-power operation with ECC-protected SRAM, hardware AES-128/256, TRNG, CAC clock accuracy monitoring, and dual watchdog timers - critical for functional safety and security-constrained embedded designs.
Technical Context
The R7FA2L1A93CFN#AA0 implements the Armv8-M architecture with TrustZone®-enabled memory protection via an 8-region MPU, supports deterministic real-time execution with GPT32×4 and AGT×2 timers, and integrates a dedicated Event Link Controller (ELC) enabling CPU-free peripheral-to-peripheral event chaining - reducing interrupt latency and power consumption in sensor fusion and motor control workflows.
Its analog subsystem includes a 19-channel 12-bit ADC with internal temperature sensor and reference voltage inputs, a single 12-bit DAC output (DA0), two low-power comparators (ACMPLP0/1), and CTSU2 supporting up to 30 touch channels - all operating under independent clock domains (HOCO/MOCO/LOCO) with trimmable oscillator accuracy for robust capacitive sensing in noisy environments.
