Product details
Overview
R7FA6T2AB3CFP#BA1 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, 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 sensing and metering systems requiring high-precision analog acquisition and long-term timekeeping.
For engineers reviewing the R7FA6T2AB3CFP#BA1 datasheet, R7FA6T2AB3CFP#BA1 pinout, R7FA6T2AB3CFP#BA1 application, or R7FA6T2AB3CFP#BA1 equivalent, key selection criteria include its 4-channel SDADC24 with programmable gain amplifier, 100-pin LQFP package with 67 GPIOs (including 3 input-only and 1 output-only pins), -40°C to +105°C industrial temperature grade, and AES-128/256 security engine with TRNG.
Technical Context
This MCU implements the Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling secure, deterministic real-time operation. Its analog subsystem integrates two independent A/D converters: a 24-bit Sigma-Delta ADC supporting differential inputs and PLL-multiplied clocking for noise-immune metrology, plus a 12-bit SAR ADC for fast control-loop sampling.
Power management includes six low-voltage detectors (LVD0–LVD_VRTC), multiple low-power modes, and dedicated IWDT with independent 15-kHz oscillator for fail-safe recovery. The Event Link Controller (ELC) enables autonomous peripheral triggering without CPU intervention, critical for energy-efficient sensor data acquisition and LCD refresh cycles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
