R7FA2L1AB2DNE#AA0 from Renesas is an ultra-low-power 48 MHz Arm® Cortex®-M23 microcontroller with 256 KB code flash, 32 KB SRAM, 12-bit ADC/DAC, Capacitive Touch Sensing Unit (CTSU2), CAN interface, and integrated security features including AES128/256 and TRNG. It operates from 1.6–5.5 V across –40°C to +85°C and targets battery-powered HMI, industrial sensors, and smart home controllers.
For engineers reviewing the R7FA2L1AB2DNE#AA0 datasheet, R7FA2L1AB2DNE#AA0 pinout, R7FA2L1AB2DNE#AA0 application, or R7FA2L1AB2DNE#AA0 equivalent, key selection criteria include its HWQFN-48 package with 34 GPIOs (4× 5-V tolerant), dual low-power timers (AGT ×2), CTSU2 for touch buttons/sliders, and CAN 2.0B compliance requiring external transceiver.
Technical Context
The R7FA2L1AB2DNE#AA0 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace. Its clock system integrates HOCO (48 MHz), SOSC (32.768 kHz), and IWDT-dedicated 15 kHz oscillator, enabling precise RTC and fail-safe watchdog operation.
Analog subsystem includes ADC12 with 19 channels (including TSN and internal Vref), DAC12 single-channel output, two ACMPLP comparators with selectable speed modes, and CTSU2 supporting up to 32 electrodes - all managed via Event Link Controller (ELC) for CPU-offload sensor processing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2L1AB2DFL#AA0 | LQFP-48 package (7 mm × 7 mm, 0.5 mm pitch); identical electrical specs but different mechanical footprint and thermal pad configuration. | Suitable where PCB reflow profile or thermal management favors exposed-pad-free LQFP over QFN. | Select R7FA2L1AB2DFL#AA0 when board assembly uses standard LQFP reflow and no thermal pad grounding is required. |
| R7FA2E1A92DFL#AA0 | RA2E1 family; 128 KB flash, no CAN, no CTSU2, lower peripheral count; same 48-pin LQFP package and voltage/temp range. | Targeted at cost-sensitive, non-touch, non-CAN applications like simple sensor nodes or LED drivers. | Choose R7FA2E1A92DFL#AA0 only if CAN, touch, and >128 KB flash are unnecessary - not a functional drop-in replacement. |
Compared with R7FA2L1AB2DNE#AA0, the R7FA2L1AB2DFL#AA0 offers identical functionality in a pin-compatible LQFP package but lacks the thermal pad; the R7FA2E1A92DFL#AA0 reduces flash and removes CAN/CTSU2, making it unsuitable for touch or vehicle network applications.

The R7FA2L1AB2DNE#AA0 supports TrustZone for hardware-isolated secure execution environments.
Does the R7FA2L1AB2DNE#AA0 support CAN communication, and what external components are required?
Yes, the R7FA2L1AB2DNE#AA0 integrates a CAN 2.0A/B controller supporting up to 32 mailboxes and both standard (11-bit) and extended (29-bit) message formats. It requires an external ISO 11898-compliant CAN transceiver connected to CTX0 and CRX0 pins. The R7FA2L1AB2DNE#AA0 does not include physical-layer drivers - transceiver selection must match bus voltage and ESD requirements.
How many capacitive touch channels does the R7FA2L1AB2DNE#AA0 support, and which pins are dedicated to CTSU2?
The R7FA2L1AB2DNE#AA0 supports up to 32 capacitive touch electrodes via its CTSU2 peripheral. Dedicated pins include TS00, TS02–CFC, TS04–TS07, TS08–CFC to TS16–CFC, TS17, TS18, TS21–TS25, and TS26–CFC to TS35–CFC - all mapped to specific GPIOs in the HWQFN-48 package. The R7FA2L1AB2DNE#AA0 also includes TSCAP for secondary touch power supply.
What are the memory resources available on the R7FA2L1AB2DNE#AA0, and how is data retention handled?
The R7FA2L1AB2DNE#AA0 provides 256 KB of code flash memory (100,000 program/erase cycles), 8 KB of data flash memory (same endurance), and 32 KB of SRAM with optional ECC or parity protection. Data flash enables reliable parameter storage across power cycles; SRAM retention is maintained during low-power modes using backup registers and RTC domain power gating. The R7FA2L1AB2DNE#AA0 includes a 128-bit unique ID for secure device identification.
What power supply configurations and low-power features does the R7FA2L1AB2DNE#AA0 offer?
The R7FA2L1AB2DNE#AA0 accepts 1.6–5.5 V on VCC and supports multiple low-power modes: Sleep, Deep Sleep, and Software Standby. It integrates a switching regulator (VCC_DCDC/VLO/VSS_DCDC) for efficient conversion, independent 15 kHz IWDT clock, and two AGT timers for asynchronous wake-up. Realtime Clock (RTC) operates in low-consumption clock mode with calendar support. The R7FA2L1AB2DNE#AA0 achieves sub-10 µA deep-sleep current with RTC active.
