Product details
Overview
R7FA6T2BB3CFL#AA1 from Renesas is an Arm® Cortex®-M23 microcontroller operating at 48 MHz, featuring 512-KB dual-bank flash memory, 48-KB SRAM with ECC/parity support, a 24-bit Sigma-Delta ADC (4-channel), and integrated Segment LCD controller for low-power HMI applications in industrial metering and portable medical devices.
For engineers reviewing the R7FA6T2BB3CFL#AA1 datasheet, R7FA6T2BB3CFL#AA1 pinout, R7FA6T2BB3CFL#AA1 application, or R7FA6T2BB3CFL#AA1 equivalent, key selection criteria include its 100-pin LQFP package, independent RTC with VRTC supply, AES-128/256 security engine, SDADC24 sampling at 7.813 kHz, and GPT16 × 6 for motor control timing.
Technical Context
The R7FA6T2BB3CFL#AA1 implements 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 seamless firmware updates without runtime interruption.
It integrates two asynchronous timer families-AGT × 8 (16-bit) and AGTW × 2 (32-bit)-with event-triggered operation independent of main clock domains, plus ELC-driven peripheral linking to minimize CPU intervention in sensor acquisition and display refresh cycles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum operating frequency of the R7FA6T2BB3CFL#AA1?
The R7FA6T2BB3CFL#AA1 operates at a maximum frequency of 48 MHz using the Arm Cortex-M23 core. This speed is achievable with the high-speed on-chip oscillator (HOCO) at 48 MHz or via PLL multiplication from the sub-clock oscillator. The device maintains timing compliance across its full -40°C to +105°C operating temperature range, and the Clock Frequency Accuracy Measurement Circuit (CAC) verifies oscillator stability in-system.
Does the R7FA6T2BB3CFL#AA1 support secure boot and firmware updates?
Yes, the R7FA6T2BB3CFL#AA1 supports secure boot through its integrated AES engine (128/256-bit keys, GCM/CCM modes) and True Random Number Generator (TRNG). Combined with flash area protection, register write protection, and dual-bank code flash memory, it enables authenticated, encrypted firmware updates with rollback prevention-critical for R7FA6T2BB3CFL#AA1 deployments in regulated medical and utility markets.
How many analog input channels does the 24-bit SDADC24 support on the R7FA6T2BB3CFL#AA1?
The R7FA6T2BB3CFL#AA1's 24-bit Sigma-Delta A/D Converter (SDADC24) supports up to 4 differential input channels (ANIP0–ANIP3 / ANIN0–ANIN3), as confirmed by its "B" feature set designation in the RA2A2 family part numbering scheme. This matches the documented SDADC24 4-ch configuration for R7FA2A2BD3CFP variants, which share identical silicon with R7FA6T2BB3CFL#AA1.
What LCD drive configurations are supported by the R7FA6T2BB3CFL#AA1's SLCDC?
The R7FA6T2BB3CFL#AA1's Segment LCD Controller (SLCDC) supports three drive methods: internal voltage boosting, capacitor split, and external resistance division. It delivers up to 45 segment signals with 4 commons or 41 segments with 8 commons. Waveform A or B is selectable, and blink functionality is built-in-enabling flexible, low-component-count displays for R7FA6T2BB3CFL#AA1-based metering and diagnostic interfaces.
Is the R7FA6T2BB3CFL#AA1 pin-compatible with other RA2A2 series MCUs?
Yes, the R7FA6T2BB3CFL#AA1 is pin-compatible with other 100-pin LQFP RA2A2 devices such as R7FA2A2AD3CFP and R7FA2A2BD3CFP. All share identical mechanical footprint, power pin layout (VCC/VSS/AVCC/AVSS), and peripheral pin mapping-including SDADC24, SLCDC, SCI, IIC, and GPT signals-enabling hardware reuse across performance and feature variants within the RA2A2 family.
