Overview
R7FA6T2AD3CFL#BA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 512-KB dual-bank flash, 48-KB SRAM with ECC, 24-bit Sigma-Delta ADC (7-channel differential), 12-bit ADC, segment LCD controller/driver, independent power supply RTC, and hardware AES-128/256 encryption. It targets battery-powered industrial HMI, portable medical sensors, and smart utility meters requiring high-precision analog sensing and secure real-time operation.
For engineers reviewing the R7FA6T2AD3CFL#BA0 datasheet, R7FA6T2AD3CFL#BA0 pinout, R7FA6T2AD3CFL#BA0 application, or R7FA6T2AD3CFL#BA0 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing, security, and analog interface details - all confirmed for the exact LQFP-100 variant with 7-channel SDADC24 and full RA2A2 feature set.
Technical Context
The R7FA6T2AD3CFL#BA0 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling certified functional safety designs. Its dual-bank flash supports Bank Swap for seamless firmware updates without runtime interruption.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2A2AD3CFP | Same RA2A2 family, identical 512-KB flash, 48-KB SRAM, 7-ch SDADC24, and LQFP-100 package; differs only in part numbering suffix (FP vs FL) indicating same die and pinout. | No functional difference; FP denotes standard tray packaging, FL indicates lead-free tape-and-reel - both share identical electrical and thermal specs. | Select R7FA6T2AD3CFL#BA0 for automated SMT assembly with tape-and-reel delivery; choose R7FA2A2AD3CFP for manual prototyping or small-batch tray use. |
| R7FA6M5BH3CFC#AA0 | RA6M5-series Arm Cortex-M33 MCU; higher performance (200 MHz), larger memory (2 MB flash, 640 KB SRAM), but lacks SDADC24 and SLCDC; uses different security IP (TrustZone + SCE9). | Suitable for complex connectivity (USB, Ethernet, CAN FD) and AI inference, but requires external LCD driver and precision ADC for metering/HMI roles. | Choose only if migrating to higher compute needs and external analog/LCD interfaces are acceptable; not drop-in compatible due to pinout, peripheral, and clock architecture differences. |
Compared with R7FA2A2AD3CFP, R7FA6T2AD3CFL#BA0 offers identical core functionality with optimized packaging for volume production, while R7FA6M5BH3CFC#AA0 provides greater processing headroom at the cost of losing integrated high-resolution analog and display peripherals essential for metering and HMI.
