Product details
Overview
R7FA6T2AB3CFM#AA0 from Renesas is an Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 512-KB dual-bank flash, 48-KB SRAM with ECC/parity, a 24-bit Sigma-Delta ADC (4-channel), 12-bit ADC (2-channel), and integrated Segment LCD controller supporting up to 41 segments × 8 commons - designed for ultra-low-power industrial HMI and metering applications.
For engineers reviewing the R7FA6T2AB3CFM#AA0 datasheet, R7FA6T2AB3CFM#AA0 pinout, R7FA6T2AB3CFM#AA0 application, or R7FA6T2AB3CFM#AA0 equivalent, key selection criteria include its 64-pin LQFP package, independent RTC with VRTC supply, AES-128/256 encryption, SDADC24 clock source flexibility (PLL-multiplied SOSC), and safety features including CAC, CRC, DOC, and IWDT.
Technical Context
The R7FA6T2AB3CFM#AA0 implements the Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling secure, deterministic real-time operation. Its dual-bank flash supports Bank Swap for robust firmware updates without runtime interruption.
It integrates two asynchronous timer families - eight 16-bit AGT and two 32-bit AGTW - all operable from sub-clock oscillator (32.768 kHz), enabling precise low-power timing. The SDADC24 uses PLL-multiplied 32.768 kHz (12.0/12.8 MHz) for high-resolution measurement while maintaining independence from main system clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2A2BD3CFM | Same RA2A2 family, identical 64-pin LQFP package, 4-channel SDADC24, but lacks 5-V tolerant I/O and has reduced I/O count (39 vs. 67). | Targeted at cost-optimized HMI where fewer GPIOs and no 5-V interfacing are acceptable. | Select R7FA2A2BD3CFM only if SDADC24 channel count and package match, and 5-V tolerance is unnecessary. |
| R7FA4M2AD3CFM | RA4M2 family, 64-pin LQFP, Arm Cortex-M33 core, 512-KB flash, but no SDADC24 or SLCDC; adds USB FS and higher-speed peripherals. | Suitable for connectivity-focused applications needing USB or Ethernet, not metrology or LCD-driven HMI. | Choose R7FA4M2AD3CFM when USB, higher CPU performance, or advanced crypto (SHA, RSA) outweigh SDADC24 and LCD driver needs. |
Compared with R7FA6T2AB3CFM#AA0, R7FA2A2BD3CFM offers identical package and SDADC24 capability but sacrifices I/O count and 5-V tolerance, while R7FA4M2AD3CFM trades metrology peripherals for USB and M33 performance - making R7FA6T2AB3CFM#AA0 uniquely balanced for low-power, high-precision, display-integrated industrial control.

FAQ
What is the maximum operating frequency of the R7FA6T2AB3CFM#AA0?
The R7FA6T2AB3CFM#AA0 operates at a maximum frequency of 48 MHz using its Arm Cortex-M23 core. This speed is achievable with the high-speed on-chip oscillator (HOCO) or main crystal oscillator (MOSC), and the PLL can be used to generate dedicated clocks for peripherals like the SDADC24 without affecting CPU timing. The R7FA6T2AB3CFM#AA0 maintains full peripheral functionality at this frequency.
Does the R7FA6T2AB3CFM#AA0 support hardware-based AES encryption?
Yes, the R7FA6T2AB3CFM#AA0 includes a dedicated AES accelerator supporting ECB, CBC, CTR, GCM, CMAC, and CCM modes with 128-bit and 256-bit key lengths. This hardware engine offloads encryption tasks from the CPU, reduces latency for secure boot and firmware updates, and meets cryptographic requirements for IEC 62443-3-3 SL2 certification. The R7FA6T2AB3CFM#AA0 also integrates a True Random Number Generator (TRNG) for key derivation.
How many channels does the 24-bit Sigma-Delta ADC (SDADC24) have on the R7FA6T2AB3CFM#AA0?
The R7FA6T2AB3CFM#AA0 features a 4-channel 24-bit Sigma-Delta ADC (SDADC24), supporting differential or single-ended input configurations across ANIP0–ANIP3 and ANIN0–ANIN3. This matches the "B" variant designation in the part number and distinguishes it from the 7-channel "A" variant. Each channel includes programmable gain amplifier (PGA) support and digital filtering, and the R7FA6T2AB3CFM#AA0 uses PLL-multiplied 32.768 kHz for precise, low-jitter conversion timing.
What LCD configuration does the R7FA6T2AB3CFM#AA0 support?
The R7FA6T2AB3CFM#AA0 integrates a Segment LCD Controller (SLCDC) supporting up to 41 segment outputs and 8 common outputs (41 × 8), or alternatively 21 segments × 4 commons. It provides three drive methods - internal voltage boosting, capacitor split, and external resistance division - and supports selectable waveforms (A/B) and blinking. This capability is confirmed for the 64-pin LQFP package variant and is fully supported in the R7FA6T2AB3CFM#AA0's pin mapping.
Is the R7FA6T2AB3CFM#AA0 qualified for industrial temperature range?
Yes, the R7FA6T2AB3CFM#AA0 is rated for operation from -40°C to +105°C ambient temperature, meeting industrial-grade reliability requirements. This rating applies to the 64-pin LQFP package (FM suffix) and is validated across all integrated peripherals including the SDADC24, RTC, and SLCDC. The R7FA6T2AB3CFM#AA0 also includes low-voltage detection (LVD) on VCC, VRTC, and EXLVDVBAT pins to ensure robust behavior under thermal and supply stress.
