Overview
R7FA6T2AB3CFP#AA1 from Renesas is an Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 512-KB dual-bank flash, 48-KB SRAM with ECC, a 24-bit Sigma-Delta ADC (4-channel), 12-bit ADC (2-channel), and integrated Segment LCD controller for low-power HMI applications in industrial metering and portable medical devices.
For engineers reviewing the R7FA6T2AB3CFP#AA1 datasheet, R7FA6T2AB3CFP#AA1 pinout, R7FA6T2AB3CFP#AA1 application, or R7FA6T2AB3CFP#AA1 equivalent, this device delivers verified low-voltage detection (7-level EXLVDVBAT, 4-level VRTC), independent power-supply RTC, AES-128/256 encryption, and hardware CRC for functional safety–critical designs requiring ASIL-B alignment and long-term supply stability.
Technical Context
The R7FA6T2AB3CFP#AA1 implements an Armv8-M architecture Cortex-M23 core with Memory Protection Unit (8 regions), debug via SW-DP, and dual-bank flash enabling safe firmware updates. Its analog subsystem integrates two independent A/D converters: a 12-bit SAR ADC (2 channels) and a 24-bit Sigma-Delta ADC (4 differential/single-ended channels) with programmable gain amplifier and PLL-derived clocking.
System-level features include Event Link Controller (ELC) for CPU-free peripheral triggering, Data Transfer Controller (DTC) for autonomous memory transfers, and Independent Watchdog Timer (IWDT) with dedicated 15-kHz oscillator-ensuring fail-safe operation in battery-backed or unattended systems.

FAQ
What is the maximum operating frequency of the R7FA6T2AB3CFP#AA1?
The R7FA6T2AB3CFP#AA1 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) or main crystal oscillator (MOSC), and is maintained across the full −40°C to +105°C industrial temperature range. The R7FA6T2AB3CFP#AA1 includes clock trim functionality to stabilize HOCO output under voltage and temperature variation.
Does the R7FA6T2AB3CFP#AA1 support secure boot and cryptographic key storage?
Yes, the R7FA6T2AB3CFP#AA1 supports secure boot through hardware-enforced flash area protection and AES-128/256 encryption with ECB/CBC/CTR/GCM/CMAC/CCM modes. It includes a True Random Number Generator (TRNG) for key derivation and supports key wrapping via the on-chip security engine. The R7FA6T2AB3CFP#AA1 does not include dedicated eFuses but uses option-setting memory and register write protection to enforce boot policy.
How many analog input channels does the R7FA6T2AB3CFP#AA1 provide?
The R7FA6T2AB3CFP#AA1 integrates two independent analog-to-digital converters: a 24-bit Sigma-Delta ADC (SDADC24) with 4 differential or single-ended input channels (ANIP0–ANIP3 / ANIN0–ANIN3), and a 12-bit successive approximation ADC (ADC12) with 2 input channels (AN000–AN001). Both converters share AVCC/AVSS supplies and support internal reference selection, with SDADC24 offering programmable gain amplifier and PLL-derived clocking for noise immunity.
What LCD drive capability does the R7FA6T2AB3CFP#AA1 offer?
The R7FA6T2AB3CFP#AA1 features a Segment LCD Controller/Driver (SLCDC) supporting up to 45 segment outputs and 4 common outputs-or 41 segments with 8 commons-configurable via software. It supports internal voltage boosting, capacitor-split, and external resistor-divider bias methods, and allows waveform A/B selection and blinking control. The R7FA6T2AB3CFP#AA1 drives LCDs directly without external bias ICs, reducing BOM count in metering and medical displays.
Is the R7FA6T2AB3CFP#AA1 pin-compatible with other RA2A2 family members?
The R7FA6T2AB3CFP#AA1 is pin-compatible with other 100-pin LQFP variants in the RA2A2 family, including R7FA2A2AD3CFP and R7FA2A2BD3CFP, sharing identical mechanical footprint, power pin locations, and core peripheral mappings. However, SDADC24 channel count (4 vs. 7), I/O count (67 vs. 73), and LCD segment capacity differ between variants-requiring schematic and layout review before substitution. The R7FA6T2AB3CFP#AA1 retains full software compatibility within the RA2A2 SDK.
