Product details
Overview
R7FA6T2AB3CFL#BA0 from Renesas is an ultra-low-power 48 MHz Arm® Cortex®-M23 microcontroller with 512-KB dual-bank flash, 48-KB SRAM, 24-bit Sigma-Delta ADC (4-channel), 12-bit ADC, segment LCD controller, independent power supply RTC, and AES-128/256 security. It targets battery-powered industrial HMI, portable medical sensors, and energy metering systems requiring high-precision analog acquisition and secure firmware updates.
For engineers reviewing the R7FA6T2AB3CFL#BA0 datasheet, R7FA6T2AB3CFL#BA0 pinout, R7FA6T2AB3CFL#BA0 application, or R7FA6T2AB3CFL#BA0 equivalent, this page delivers verified specifications, validated package mapping, confirmed pin functions for LQFP-100, real-world use cases, and two technically documented alternative parts with explicit functional and application-level differences.
Technical Context
The R7FA6T2AB3CFL#BA0 implements the 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.
Analog subsystem integration includes a 24-bit Sigma-Delta ADC with programmable gain amplifier (PGA), differential input support across 4 channels, and dedicated PLL clocking (12.0/12.8 MHz) derived from the 32.768 kHz sub-clock oscillator-ensuring high-resolution measurement stability independent of main system clock jitter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power Arm Cortex-M23 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2A2AD3CFP | Same RA2A2 family, but 7-channel SDADC24, 100-pin LQFP, no 5-V tolerant I/O. | Required for applications needing >4 SDADC24 channels (e.g., multi-phase energy monitoring). | Select R7FA2A2AD3CFP when higher channel count justifies larger footprint and absence of 5-V tolerance is acceptable. |
| R7FA4M1AB3CFB | RA4M1 family, Cortex-M4F core, 48 MHz, 512-KB flash, but no SDADC24 or LCD controller; adds FPU and USB FS. | Suitable for motor control or connectivity-heavy designs where analog precision is secondary to computation or interface bandwidth. | Choose R7FA4M1AB3CFB only if floating-point math or USB host/device is mandatory-and SDADC24/LCD are unnecessary. |
Compared with R7FA6T2AB3CFL#BA0, R7FA2A2AD3CFP offers greater analog channel density at identical package size but lacks 5-V tolerant I/O, while R7FA4M1AB3CFB trades precision analog and HMI peripherals for computational throughput and USB-making it unsuitable for metering or LCD-based HMI without external components.
