Product details
Overview
R7FA6T2BB3CFL#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, a 24-bit Sigma-Delta ADC (4-channel), and integrated segment LCD controller for low-power industrial HMI applications.
For engineers reviewing the R7FA6T2BB3CFL#AA0 datasheet, R7FA6T2BB3CFL#AA0 pinout, R7FA6T2BB3CFL#AA0 application, or R7FA6T2BB3CFL#AA0 equivalent, this MCU delivers verified low-power operation across -40°C to +105°C, on-chip security (AES-128/256, TRNG), and hardware safety features including CAC, CRC, IWDT, and SDADC24 self-diagnosis - critical for medical, metering, and industrial control designs requiring functional safety compliance.
Technical Context
This MCU implements the Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling secure, deterministic real-time execution. Its dual-bank flash supports Bank Swap for seamless firmware updates without runtime interruption.
The analog subsystem integrates two independent A/D converters: a 12-bit SAR ADC (4 channels) and a 24-bit Sigma-Delta ADC (4 differential/single-ended channels) with programmable gain amplifier, PLL-derived clocking, and built-in self-test capability - optimized for precision sensor signal acquisition in battery-powered equipment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6T2BB3CFP#AA0 | Same core, memory, and peripherals but in 100-pin LQFP (14×14 mm) instead of 100-pin LQFP (14×14 mm, 0.5 mm pitch) - identical pinout and footprint. | No functional difference; differs only in packing (tray vs. tape-and-reel) and marking format. | Select R7FA6T2BB3CFP#AA0 for tray-based procurement or when reel packaging is not required. |
| R7FA2A2BD3CFP#AA0 | RA2A2-series sibling with same 48 MHz M23 core, 512-KB flash, 48-KB SRAM, but only 4-channel SDADC24 and no SLCDC support. | Suitable for non-LCD applications requiring lower-cost analog sensing; lacks segment LCD driver and independent RTC power domain. | Choose R7FA2A2BD3CFP#AA0 when LCD functionality is unnecessary and cost optimization is prioritized over HMI integration. |
