Product details
Overview
R7FA6T2AD3CFP#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 code flash, 48-KB SRAM with ECC, a 24-bit Sigma-Delta ADC (7-channel), 12-bit SAR ADC (4-channel), segment LCD controller/driver, independent power supply RTC, and hardware AES-128/256 encryption. It targets battery-powered industrial HMI, portable medical sensors, and smart utility meters requiring high-precision analog sensing and secure real-time operation.
For engineers reviewing the R7FA6T2AD3CFP#AA0 datasheet, R7FA6T2AD3CFP#AA0 pinout, R7FA6T2AD3CFP#AA0 application, or R7FA6T2AD3CFP#AA0 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-ready procurement details - all grounded in Renesas R01DS0418EJ0130 Rev.1.30 documentation.
Technical Context
This MCU implements the Armv8-M architecture with Memory Protection Unit (8 regions), debug via SW-DP, and low-power asynchronous timers (AGT ×8, AGTW ×2). Its dual-bank flash enables safe firmware updates without runtime interruption, while the Memory Mirror Function (MMF) decouples link address from physical load location.
The analog subsystem integrates two independent A/D converters: the SDADC24 supports differential inputs with programmable gain and PLL-derived clocking (32.768 kHz × 368–384), and the ADC12 provides fast 12-bit sampling with temperature sensor and internal reference support. The SLCDC drives up to 45 segments × 4 commons or 41 segments × 8 commons using internal boosting or external resistor division.
