Product details
Overview
R7FA6T2AB3CNE#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 hardware AES/TRNG security. It targets battery-powered industrial HMI, portable medical sensors, and smart utility meters requiring high-precision analog measurement and secure real-time operation.
For engineers reviewing the R7FA6T2AB3CNE#AA0 datasheet, R7FA6T2AB3CNE#AA0 pinout, R7FA6T2AB3CNE#AA0 application, or R7FA6T2AB3CNE#AA0 equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +105°C operating range, SDADC24 4-channel configuration, integrated SLCDC supporting up to 45 segments × 4 commons, and dual-bank flash enabling safe firmware updates without external memory.
Technical Context
This MCU implements the Armv8-M architecture with Memory Protection Unit (8 regions), debug via SW-DP, and safety features including ECC on 16 KB of SRAM, CAC for clock accuracy monitoring, and independent watchdog (IWDT) with dedicated 15 kHz oscillator. Its analog subsystem integrates two A/D converters: a 12-bit SAR ADC (4 inputs) and a 24-bit sigma-delta converter (4 differential/single-ended channels) with programmable gain amplifier and internal reference voltage (AVRT).
The system includes Event Link Controller (ELC) for peripheral-to-peripheral event routing without CPU intervention, Data Transfer Controller (DTC) for autonomous data movement, and 6× GPT16 timers plus 8× AGT and 2× AGTW low-power timers - enabling precise motor control, pulse-width measurement, and calendar-based RTC wake-up while maintaining sub-μA sleep current.

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, but 7-channel SDADC24, 100-pin LQFP, identical flash/SRAM/security peripherals | Required where higher-resolution multi-sensor systems (e.g., 7-wire load cell arrays) demand additional SDADC inputs | Select R7FA2A2AD3CFP when full 7-channel SDADC24 capability is needed; pin-compatible but requires layout verification for unused ANIP/ANIN pins |
| R7FA4M2AD3CFP | RA4M2 family, Arm Cortex-M33 @ 100 MHz, 1 MB flash, no SDADC24, adds USB FS, CAN FD, and larger GPIO count | Suitable for applications needing higher compute throughput, connectivity (USB/CAN), or larger code footprint - not for precision analog focus | Choose R7FA4M2AD3CFP when migrating to higher-performance control with communication interfaces; not a drop-in replacement due to different analog subsystem and pinout |
Compared with R7FA2A2BD3CFP (7-channel variant) and R7FA4M2AD3CFP (higher-performance RA4M2), the R7FA6T2AB3CNE#AA0 delivers optimal balance of ultra-low-power operation, 24-bit analog precision, and integrated LCD drive - making it uniquely suited for cost-sensitive, battery-operated HMI and sensor edge nodes where SDADC channel count and power efficiency outweigh raw CPU speed or connectivity needs.

FAQ
What is the maximum sampling rate of the 24-bit SDADC24 in R7FA6T2AB3CNE#AA0?
The 24-bit Sigma-Delta A/D Converter (SDADC24) in R7FA6T2AB3CNE#AA0 supports two configurable sampling rates: 7.813 kHz / 8.333 kHz (high-speed mode) or 3.906 kHz / 4.166 kHz (high-accuracy mode), depending on clock source selection (MOSC or PLL-multiplied SOSC). These rates are confirmed in the R01DS0418EJ0130 datasheet Section 1.1 and Table 1.8.
Does R7FA6T2AB3CNE#AA0 support pin-compatible migration from other RA2A2 devices?
R7FA6T2AB3CNE#AA0 shares the same 100-pin LQFP package and pinout as other RA2A2 100-pin variants like R7FA2A2AD3CFP and R7FA2A2BD3CFP. However, SDADC24 channel count differs (4 vs. 7), so unused ANIP/ANIN pins must be left unconnected or configured as GPIO. Full pin compatibility is maintained for power, clock, debug, and core peripherals.
How does the Memory Mirror Function (MMF) benefit firmware development for R7FA6T2AB3CNE#AA0?
The Memory Mirror Function (MMF) in R7FA6T2AB3CNE#AA0 allows application code to be linked to a fixed virtual address (e.g., 0x0000_0000) while physically loaded into either flash bank - simplifying bootloader design and enabling atomic firmware updates. This avoids address remapping logic and ensures deterministic execution regardless of flash bank usage.
What LCD drive configurations does the SLCDC in R7FA6T2AB3CNE#AA0 support?
R7FA6T2AB3CNE#AA0's Segment LCD Controller (SLCDC) supports two configurations: 45 segment signals × 4 common signals (when 8-com is disabled) or 41 segment signals × 8 common signals (when 8-com is enabled). Drive methods include internal voltage boosting, capacitor split, and external resistor division - all selectable in firmware per application requirements.
Is hardware AES encryption in R7FA6T2AB3CNE#AA0 limited to specific cipher modes or key lengths?
R7FA6T2AB3CNE#AA0 supports AES-128 and AES-256 with ECB, CBC, CTR, GCM, CMAC, and CCM cipher modes - all implemented in dedicated hardware accelerators. Key scheduling, encryption, and authentication (for GCM/CCM) execute independently of the CPU, enabling secure wireless firmware updates and sensor data confidentiality without performance penalty.
