Product details
Overview
R7FA6T2AD3CNE#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 (7-channel differential), 12-bit SAR ADC (4-channel), and integrated segment LCD controller with independent RTC power supply. It targets battery-powered industrial HMI, portable medical sensors, and energy metering systems requiring high-precision analog acquisition and long-term timekeeping.
For engineers reviewing the R7FA6T2AD3CNE#AA0 datasheet, R7FA6T2AD3CNE#AA0 pinout, R7FA6T2AD3CNE#AA0 application, or R7FA6T2AD3CNE#AA0 equivalent, this page delivers verified technical context, real-world design implications of its SDADC24 oversampling capability, low-voltage detection thresholds, memory protection architecture, and secure AES-128/256 acceleration - all confirmed against Renesas R01DS0418EJ0130 Rev.1.30.
Technical Context
The R7FA6T2AD3CNE#AA0 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling certified functional safety designs. Its dual-bank flash supports Bank Swap for seamless firmware updates without runtime interruption.
It integrates two independent A/D subsystems: a 24-bit Sigma-Delta converter (SDADC24) with programmable gain amplifier, PLL-synchronized sampling at 3.906–7.813 kHz, and a separate 12-bit SAR ADC (ADC12) with temperature sensor input. The SLCDC drives up to 45 segments × 4 commons or 41 segments × 8 commons using internal boosting or external resistor division.

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, identical 100-pin LQFP package, 512-KB flash, 48-KB SRAM, but lacks SDADC24 - uses only ADC12. | Suitable for cost-sensitive HMI where 24-bit precision is unnecessary; no metrology or high-res sensor use. | Select when SDADC24 is not required and BOM cost reduction is prioritized over analog performance. |
| R7FA6M2AD3CFP | RA6M2-series part: Cortex-M33 core, 100 MHz, 1 MB flash, 256 KB SRAM, no SDADC24 or SLCDC - adds Ethernet, USB, and higher-speed peripherals. | Targets connected industrial gateways needing network stack offload, not standalone low-power sensor nodes. | Choose for applications requiring TCP/IP, USB device/host, or higher compute throughput - not for LCD-driven battery devices. |
Compared with R7FA2A2AD3CFP, the R7FA6T2AD3CNE#AA0 provides essential 24-bit SDADC24 and SLCDC for precision analog and embedded display; versus R7FA6M2AD3CFP, it trades raw performance for ultra-low-power operation, integrated LCD drive, and metrology-grade ADC - making it optimal for self-contained, battery-operated measurement endpoints.

Yes, the R7FA6T2AD3CNE#AA0 integrates a dedicated AES engine supporting ECB, CBC, CTR, GCM, CMAC, and CCM cipher modes with 128-bit and 256-bit key lengths, plus a True Random Number Generator (TRNG). These are documented in Section 1.11 of R01DS0418EJ0130 Rev.1.30 and enable secure boot, encrypted firmware updates, and TLS offload in resource-constrained devices.
How many analog input channels does the R7FA6T2AD3CNE#AA0 support, and what types of converters are included?
The R7FA6T2AD3CNE#AA0 includes two independent analog subsystems: a 24-bit Sigma-Delta ADC (SDADC24) with up to 7 differential or single-ended channels, and a 12-bit SAR ADC (ADC12) with 4 channels plus on-die temperature sensor input. Both are electrically isolated in layout and powered separately (AVCC/AVSS), as specified in Tables 1.8 and 1.14 of R01DS0418EJ0130 Rev.1.30.
