Product details
Overview
R7FA6T2AB3CNB#AA0 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 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 R7FA6T2AB3CNB#AA0 datasheet, R7FA6T2AB3CNB#AA0 pinout, R7FA6T2AB3CNB#AA0 application, or R7FA6T2AB3CNB#AA0 equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, functional pin roles, safety-certified features (ECC, CAC, IWDT), and two validated alternative parts for design flexibility in low-power embedded systems.
Technical Context
The R7FA6T2AB3CNB#AA0 implements 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 firmware updates without system interruption, while the 24-bit sigma-delta ADC operates at 3.906–7.813 kHz sampling with programmable gain amplifier and differential input support.
Power management includes seven low-voltage detectors (LVD0–LVD_VRTC), independent RTC powered by VRTC, and clock sources ranging from 32.768 kHz SOSC to 48 MHz HOCO with PLL multiplication. The Event Link Controller (ELC) enables autonomous peripheral-to-peripheral triggering, reducing CPU load in sensor acquisition and display refresh cycles.

FAQ
What is the maximum operating frequency of the R7FA6T2AB3CNB#AA0?
The R7FA6T2AB3CNB#AA0 operates at a maximum frequency of 48 MHz using its Arm Cortex-M23 core. This speed is achievable with the high-speed on-chip oscillator (HOCO) at 48 MHz or via PLL multiplication from the sub-clock oscillator (32.768 kHz). All peripherals-including SDADC24, GPT, and SLCDC-are fully functional at this clock rate, and timing constraints are guaranteed across the −40°C to +105°C operating range.
Does the R7FA6T2AB3CNB#AA0 support hardware-accelerated AES encryption?
Yes, the R7FA6T2AB3CNB#AA0 integrates a dedicated hardware AES engine supporting ECB, CBC, CTR, GCM, CMAC, and CCM modes with 128-bit and 256-bit key lengths. This offloads encryption/decryption from the CPU, enabling secure OTA firmware updates and encrypted sensor data transmission without compromising real-time responsiveness. The TRNG provides cryptographically secure keys for session establishment.
How many SDADC24 input channels does the R7FA6T2AB3CNB#AA0 have?
The R7FA6T2AB3CNB#AA0 features a 24-bit sigma-delta ADC (SDADC24) with four differential input channels (ANIP0/ANIN0 through ANIP3/ANIN3), supporting both differential and single-ended configurations. This matches the "B" variant designation in the RA2A2 part numbering scheme, distinguishing it from the 7-channel "A" variant (e.g., R7FA2A2AD3CFP). Each channel includes programmable gain and digital filtering.
What LCD segment drive capability does the R7FA6T2AB3CNB#AA0 provide?
The R7FA6T2AB3CNB#AA0's Segment LCD Controller (SLCDC) supports up to 45 segment outputs and 4 common outputs-or 41 segments with 8 commons-configurable via register settings. It offers three voltage generation methods (internal boost, capacitor split, external resistor division) and selectable waveforms (A/B) to optimize contrast and power consumption for custom LCD glass designs in industrial and medical displays.
Is the R7FA6T2AB3CNB#AA0 pin-compatible with other RA2A2 MCUs?
Yes, the R7FA6T2AB3CNB#AA0 is pin-compatible with other 100-pin LQFP RA2A2 variants including R7FA2A2AD3CFP and R7FA2A2BD3CFP. All share identical mechanical footprint, power pin locations, and peripheral pin mappings (e.g., SDADC24, SLCDC, SCI, I2C). Firmware portability is further ensured by Renesas' unified FSP (Flexible Software Package) and HAL drivers across the RA2A2 group.
