Overview
R7FA6T2AD3CFP#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/parity, a 24-bit Sigma-Delta ADC (7-channel), 12-bit ADC (4-channel), segment LCD controller (45 seg × 4 com), and independent power supply RTC. It targets ultra-low-power industrial HMI, portable medical sensors, and battery-backed metering systems requiring high-precision analog acquisition and long-term timekeeping.
For engineers reviewing the R7FA6T2AD3CFP#AA1 datasheet, R7FA6T2AD3CFP#AA1 pinout, R7FA6T2AD3CFP#AA1 application, or R7FA6T2AD3CFP#AA1 equivalent, this device delivers verified sigma-delta resolution for strain gauge or thermocouple interfaces, hardware-accelerated AES-128/256 for secure firmware updates, and low-power asynchronous timers (AGT/AGTW) enabling sub-μA sleep with wake-on-analog-threshold capability.
Technical Context
The R7FA6T2AD3CFP#AA1 implements Armv8-M architecture with Memory Protection Unit (8 regions), debug via SW-DP, and CoreSight MTB trace. Its dual-bank flash supports bank-swap firmware updates without runtime interruption.

It also includes a True Random Number Generator (TRNG) for cryptographic key derivation and nonce generation. These features enable secure boot, firmware authentication, and end-to-end encrypted sensor data transmission without CPU overhead.
How does the 24-bit Sigma-Delta ADC (SDADC24) achieve high accuracy in the R7FA6T2AD3CFP#AA1?
The SDADC24 in the R7FA6T2AD3CFP#AA1 achieves high accuracy through a dedicated PLL clock derived from the 32.768-kHz sub-clock oscillator, isolating conversion timing from main system clock jitter. It supports differential or single-ended inputs across 7 channels, programmable gain amplification, and built-in digital filtering (high-pass and phase-adjustment circuits), delivering effective resolution >20 bits at 3.906 kHz sampling rate.
What LCD driving capabilities does the R7FA6T2AD3CFP#AA1 provide?
The R7FA6T2AD3CFP#AA1 includes a Segment LCD Controller (SLCDC) supporting up to 45 segments and 4 commons (or 41 segments and 8 commons). It offers three voltage-generation methods - internal boosting, capacitor split, and external resistor division - plus selectable waveform A or B output. This eliminates need for external LCD bias ICs and supports direct drive of static or multiplexed displays in battery-powered applications.
Is the RTC in the R7FA6T2AD3CFP#AA1 truly independent of the main power supply?
Yes, the R7FA6T2AD3CFP#AA1 features an independent power supply RTC powered via the VRTC pin, allowing continuous calendar operation (99-year range), alarm triggering, and clock correction even when VCC is absent or in deep sleep.
