Product details
Overview
R7FA6T2BD3CFL#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 RTC, and hardware AES/TRNG 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 R7FA6T2BD3CFL#BA0 datasheet, R7FA6T2BD3CFL#BA0 pinout, R7FA6T2BD3CFL#BA0 application, or R7FA6T2BD3CFL#BA0 equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, validated pin functions for SDADC24 and SLCDC, real-world use cases in low-power sensing and display control, and two confirmed alternative parts with documented functional and channel-count differences.
Technical Context
The R7FA6T2BD3CFL#BA0 implements an Armv8-M architecture Cortex-M23 core with Memory Protection Unit (8 regions), debug via SW-DP, and integrated safety features including ECC on 16 KB of SRAM, CAC clock accuracy monitoring, and independent watchdog (IWDT) with dedicated 15 kHz oscillator. Its analog subsystem centers on a programmable-gain 24-bit Sigma-Delta ADC supporting differential inputs at 7.813 kHz sampling rate using PLL-multiplied 32.768 kHz clock.
System-level integration includes Event Link Controller (ELC) for CPU-free peripheral triggering, Data Transfer Controller (DTC) for autonomous data movement, and Memory Mirror Function (MMF) enabling seamless bank-swap firmware updates. The segment LCD controller supports up to 45 segments × 4 commons or 41 segments × 8 commons with selectable voltage-boosting methods and waveform A/B output.

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, 7-channel SDADC24, identical 100-pin LQFP package and pinout. | Supports higher-channel-count analog sensing (e.g., multi-phase energy metering, multi-sensor industrial nodes). | Select when >4 SDADC24 channels are required; otherwise R7FA6T2BD3CFL#BA0 offers optimal cost/power for 4-channel use cases. |
| R7FA4M2AD3CFP | RA4M2 family part; Cortex-M33 core, 200 MHz, 1 MB flash, but no SDADC24 or SLCDC; uses different peripheral set and pinout. | Targets high-performance motor control or connectivity-heavy applications where analog precision and LCD drive are secondary. | Choose only if migrating to higher compute throughput and external display/LCD drivers are acceptable; not pin-compatible or functionally equivalent. |
Compared with R7FA2A2AD3CFP, R7FA6T2BD3CFL#BA0 reduces analog channel count and cost while retaining identical security, RTC, and low-power features; versus R7FA4M2AD3CFP, it trades raw performance for integrated analog and display peripherals essential in resource-constrained sensing endpoints.

FAQ
What is the maximum operating frequency and core architecture of the R7FA6T2BD3CFL#BA0?
The R7FA6T2BD3CFL#BA0 operates at a maximum frequency of 48 MHz and is built on the Arm Cortex-M23 core implementing the Armv8-M architecture. It includes an 8-region Memory Protection Unit (MPU), SW-DP debug interface, and supports TrustZone security extensions. This architecture enables deterministic real-time performance with hardware-enforced memory isolation critical for certified industrial firmware.
Does the R7FA6T2BD3CFL#BA0 support hardware-accelerated cryptography?
Yes, the R7FA6T2BD3CFL#BA0 integrates a hardware AES engine supporting ECB, CBC, CTR, GCM, CMAC, and CCM modes with 128-bit and 256-bit keys, plus a True Random Number Generator (TRNG). These peripherals operate independently of the CPU, enabling secure boot, encrypted communication, and key derivation without exposing secrets in software or degrading real-time responsiveness.
How many channels does the 24-bit Sigma-Delta ADC support on the R7FA6T2BD3CFL#BA0?
The R7FA6T2BD3CFL#BA0 features a 24-bit Sigma-Delta ADC (SDADC24) with 4 differential input channels (ANIP0–ANIP3 / ANIN0–ANIN3). This configuration is explicitly defined in the RA2A2 product matrix and distinguishes it from the 7-channel variant (e.g., R7FA2A2AD3CFP); no software or configuration can extend this to more than 4 physical SDADC24 channels.
What LCD driving capabilities does the R7FA6T2BD3CFL#BA0 provide?
The R7FA6T2BD3CFL#BA0 integrates a Segment LCD Controller/Driver (SLCDC) supporting up to 45 segment outputs × 4 common outputs or 41 segments × 8 commons. It offers three configurable drive methods-internal voltage boosting, capacitor-split, and external resistor division-and supports waveform A/B selection and blinking control, eliminating need for external LCD bias ICs.
Is the R7FA6T2BD3CFL#BA0 pin-compatible with other RA2A2 family members?
The R7FA6T2BD3CFL#BA0 shares the same 100-pin LQFP package (PLQP0100KB-B) and pinout with R7FA2A2AD3CFP and R7FA2A2BD3CFP, making it pin-compatible within the RA2A2 100-pin variants. However, functional differences exist-such as SDADC24 channel count and SLCDC segment count-so PCB layout is reusable, but firmware must account for peripheral availability.
