Product details
Overview
R7FA6T2BD3CFM#BA1 from Renesas is an ultra-low-power 48 MHz Arm® Cortex®-M23 microcontroller with 512-KB dual-bank flash, 48-KB SRAM, 24-bit sigma-delta ADC (4-channel), 12-bit ADC, segment LCD controller, independent-power RTC, and hardware AES/TRNG security. 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 R7FA6T2BD3CFM#BA1 datasheet, R7FA6T2BD3CFM#BA1 pinout, R7FA6T2BD3CFM#BA1 application, or R7FA6T2BD3CFM#BA1 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +105°C operating range, 1.6–5.5 V supply, SDADC24 channel count, SLCDC segment/com configuration, and integrated ECC/SRAM parity for functional safety compliance.
Technical Context
The R7FA6T2BD3CFM#BA1 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight debug support (SW-DP, MTB-M23). Its dual-bank flash enables safe firmware updates via Bank Swap, while the Memory Mirror Function (MMF) decouples link address from physical load location-simplifying bootloader design and field upgrades.
Analog subsystem integration includes two independent A/D converters: a 12-bit SAR ADC (4 ch) for fast control-loop sampling and a 24-bit sigma-delta ADC (4 ch differential/single-ended) with programmable gain amplifier, PLL-derived clocking, and built-in self-diagnosis. The SLCDC supports up to 21 segments × 4 commons or 17 segments × 8 commons with selectable voltage-boosting methods.
