Product details
Overview
R7FA6T2AD3CFL#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, a 24-bit sigma-delta ADC (7-channel), 12-bit ADC, segment LCD controller, independent-power RTC, and hardware AES/256 encryption. It targets battery-powered industrial sensors and portable medical devices requiring high-precision analog measurement and secure firmware updates.
For engineers reviewing the R7FA6T2AD3CFL#AA0 datasheet, R7FA6T2AD3CFL#AA0 pinout, R7FA6T2AD3CFL#AA0 application, or R7FA6T2AD3CFL#AA0 equivalent, key selection criteria include its 100-pin LQFP package with 67 GPIOs, 7-channel SDADC24 for high-resolution sensor interfacing, dual-bank flash enabling safe over-the-air updates, and integrated security features meeting IEC 62443-3-3 SL2 requirements.
Technical Context
The R7FA6T2AD3CFL#AA0 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, supporting deterministic real-time operation in safety-critical environments. Its clock system integrates HOCO (48 MHz), SOSC (32.768 kHz), and PLL-derived SDADC24 clocks for synchronized high-accuracy conversion.
Analog subsystem integration includes SDADC24 with programmable gain amplifier, differential input support, and phase-adjusted digital filtering - all operating independently of CPU load via DTC-triggered transfers. The SLCDC supports 45-segment × 4-common LCD drive with internal voltage boosting, eliminating external charge pumps in portable HMI designs.

The R7FA6T2AD3CFL#AA0's 24-bit sigma-delta ADC (SDADC24) supports up to 7 differential or 14 single-ended analog input channels via dedicated ANIPn/ANINn pins. Each channel includes programmable gain amplifier (PGA) stages and configurable digital filtering. The R7FA6T2AD3CFL#AA0 datasheet confirms full 7-channel capability for this specific part number, matching the "A" variant designation in the RA2A2 family naming scheme.
What LCD configuration options does the R7FA6T2AD3CFL#AA0's SLCDC support?
The R7FA6T2AD3CFL#AA0's Segment LCD Controller (SLCDC) supports up to 45 segment outputs and 4 common outputs (or 41 segments × 8 commons), with selectable drive waveforms (A or B), internal voltage boosting, capacitor-split, or external resistor-divider bias methods. The R7FA6T2AD3CFL#AA0 implements all three bias modes and provides dedicated VL1–VL4 and CAPH/CAPL pins for flexible LCD panel integration without external components.
Is the R7FA6T2AD3CFL#AA0 qualified for industrial temperature operation?
Yes, the R7FA6T2AD3CFL#AA0 is rated for industrial temperature operation from -40°C to +105°C, verified across all specified electrical parameters including SDADC24 accuracy, flash retention, and RTC calendar function.
