Product details
Overview
R7FA2L1AB2DFM#AA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 256 KB code flash, 32 KB SRAM, 12-bit ADC/DAC, Capacitive Touch Sensing Unit (CTSU2), CAN interface, and integrated security (AES128/256, TRNG). It targets battery-powered HMI, industrial sensors, and smart metering where low power, analog integration, and functional safety are critical.
For engineers reviewing the R7FA2L1AB2DFM#AA0 datasheet, R7FA2L1AB2DFM#AA0 pinout, R7FA2L1AB2DFM#AA0 application, or R7FA2L1AB2DFM#AA0 equivalent, key selection criteria include its -40°C to +85°C temperature grade, 64-pin LQFP package, CTSU2-based touch interface support, dual 12-bit analog converters with internal temperature sensor, and ISO 11898-1-compliant CAN module requiring external transceiver.
Technical Context
The R7FA2L1AB2DFM#AA0 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling secure, deterministic real-time operation. Its system-level features include Event Link Controller (ELC) for CPU-free peripheral chaining and Data Transfer Controller (DTC) for autonomous memory transfers triggered by interrupts.
Power management integrates a switching regulator (VCC_DCDC/VLO), multiple clock sources (HOCO/MOCO/LOCO/SOSC), and low-power modes with AGT timers and RTC in calendar/binary count modes. Safety mechanisms include ECC in SRAM, ADC self-diagnosis, CAC for clock accuracy validation, and independent watchdog (IWDT) with dedicated 15 kHz oscillator.

No, the R7FA2L1AB2DFM#AA0 includes only the CAN protocol controller compliant with ISO 11898-1 (CAN 2.0A/B), supporting up to 32 mailboxes and both standard/extended frames. An external ISO 11898-2 physical layer transceiver is required for bus connection. The R7FA2L1AB2DFM#AA0 provides CRX0 and CTX0 pins for this interface, but no integrated driver or termination.
What touch sensing capability does the R7FA2L1AB2DFM#AA0 provide?
The R7FA2L1AB2DFM#AA0 integrates the Capacitive Sensing Unit version 2 (CTSU2), supporting up to 32 touch channels (e.g., TS00–TS35-CFC) for mutual or self-capacitance measurement. It enables robust, low-power touch UIs with built-in noise cancellation and water-tolerance algorithms - no external touch controller needed. The R7FA2L1AB2DFM#AA0 uses dedicated TSCAP and touch I/O pins, and supports proximity, slider, and matrix keypad configurations.
How is security implemented in the R7FA2L1AB2DFM#AA0?
Security in the R7FA2L1AB2DFM#AA0 includes hardware-accelerated AES128/256 encryption, a True Random Number Generator (TRNG), Memory Protection Unit (MPU), register write protection (PRCR), flash area protection, and secure boot support. These features enable secure firmware updates, encrypted data storage, and runtime integrity checks - meeting baseline requirements for IEC 62443-3-3 and PSA Certified Level 1. The R7FA2L1AB2DFM#AA0 does not include a secure element or PKI accelerator.
What are the power supply requirements for the R7FA2L1AB2DFM#AA0?
The R7FA2L1AB2DFM#AA0 requires a 1.6 V to 5.5 V single-supply input on VCC, with separate analog supply pins (AVCC0/AVSS0) and a dedicated switching regulator domain (VCC_DCDC/VLO/VSS_DCDC). It supports ultra-low-power operation down to 0.7 µA in deep standby mode with RTC active. The R7FA2L1AB2DFM#AA0 integrates a configurable DC-DC converter to improve efficiency in battery-powered designs, reducing external component count.
