Product details
Overview
R7FA6T2BD3CNB#AA0 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/parity, 24-bit Sigma-Delta ADC (4-channel), 12-bit ADC (2-channel), independent power supply RTC, and integrated Segment LCD controller for 45-segment × 4-common or 41-segment × 8-common displays. It targets battery-powered industrial HMI, portable medical sensors, and energy metering systems requiring high-precision analog acquisition and secure real-time control.
For engineers reviewing the R7FA6T2BD3CNB#AA0 datasheet, R7FA6T2BD3CNB#AA0 pinout, R7FA6T2BD3CNB#AA0 application, or R7FA6T2BD3CNB#AA0 equivalent, key selection criteria include its 4-channel SDADC24 with programmable gain amplifier, dual-bank flash for safe firmware updates, AES-128/256 encryption with TRNG, and 100-pin LQFP package supporting 67 general-purpose I/Os with 5-V tolerance on 3 pins.
Technical Context
This MCU implements the Armv8-M architecture with Memory Protection Unit (8 regions), CoreSight™ MTB-M23 trace, and SW-DP debug interface. Its analog subsystem integrates two independent A/D converters: a 24-bit Sigma-Delta ADC (SDADC24) with differential input support and selectable sampling rates (3.906–8.333 kHz), and a 12-bit successive-approximation ADC (ADC12) with temperature sensor and internal reference inputs.
Power management includes six low-voltage detectors (LVD0–LVD_VRTC), multiple clock sources (HOCO/MOCO/LOCO/SOSC/MOSC), and dedicated low-power timers (AGT × 8, AGTW × 2). The Event Link Controller (ELC) enables hardware-triggered peripheral chaining without CPU intervention, while the Data Transfer Controller (DTC) supports autonomous memory transfers on interrupt.

FAQ
What is the maximum operating frequency and core architecture of the R7FA6T2BD3CNB#AA0?
The R7FA6T2BD3CNB#AA0 features an Arm Cortex-M23 core compliant with the Armv8-M architecture, operating at a maximum frequency of 48 MHz. It includes an Arm Memory Protection Unit with 8 configurable regions, CoreSight™ MTB-M23 trace, and SW-DP debug interface. This architecture delivers deterministic real-time performance with enhanced security features essential for certified industrial and medical applications. The R7FA6T2BD3CNB#AA0 achieves this speed while maintaining ultra-low power consumption through dynamic clock gating and multiple low-power modes.
How many analog input channels does the R7FA6T2BD3CNB#AA0 support, and what are their types?
The R7FA6T2BD3CNB#AA0 integrates two distinct analog subsystems: a 24-bit Sigma-Delta A/D Converter (SDADC24) with 4 differential or single-ended input channels (ANIP0–ANIP3 / ANIN0–ANIN3), and a 12-bit successive-approximation A/D Converter (ADC12) with 2 input channels (AN000–AN001) plus on-chip temperature sensor output. The SDADC24 supports programmable gain amplification and selectable sampling rates (3.906 kHz or 7.813 kHz), making the R7FA6T2BD3CNB#AA0 suitable for high-precision current/voltage sensing in energy metering and medical instrumentation.
Does the R7FA6T2BD3CNB#AA0 include hardware security features, and which ones are implemented?
Yes, the R7FA6T2BD3CNB#AA0 includes dedicated hardware security features: AES-128/256 encryption engine supporting ECB, CBC, CTR, GCM, CMAC, and CCM cipher modes; True Random Number Generator (TRNG); Clock Frequency Accuracy Measurement Circuit (CAC); Cyclic Redundancy Check (CRC) module; Data Operation Circuit (DOC); and register write protection. These features enable secure boot, encrypted firmware updates, and runtime integrity checking-all implemented in silicon without software overhead. The R7FA6T2BD3CNB#AA0 leverages these to meet IEC 62443 and UL 60730 functional safety requirements.

It provides VL1–VL4 voltage outputs and CAPH/CAPL pins to implement internal voltage boosting, capacitor-split, or external resistor-divider bias methods. Waveform A or B can be selected per segment, and blinking is supported. This eliminates external LCD bias ICs and reduces BOM cost for industrial panel meters and portable medical displays. The R7FA6T2BD3CNB#AA0's SLCDC operates independently of the main CPU clock, ensuring stable display drive during low-power states.
What package type and pin count does the R7FA6T2BD3CNB#AA0 use, and what are its key I/O characteristics?
The R7FA6T2BD3CNB#AA0 uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with 67 general-purpose I/O pins, 3 input-only pins, and 1 output-only pin.
