Product details
Overview
R7FA6T2AB3CFM#BA0 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/parity, a 24-bit Sigma-Delta ADC (4-channel), 12-bit ADC (2-channel), segment LCD controller (41 seg × 8 com), 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 measurement and secure real-time operation.
For engineers reviewing the R7FA6T2AB3CFM#BA0 datasheet, R7FA6T2AB3CFM#BA0 pinout, R7FA6T2AB3CFM#BA0 application, or R7FA6T2AB3CFM#BA0 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +105°C industrial temperature rating, SDADC24 4-channel differential input capability, SLCDC support for 8-common LCDs, and integrated security features including TRNG and CAC for clock accuracy validation.
Technical Context
The R7FA6T2AB3CFM#BA0 implements the Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling certified functional safety designs. Its analog subsystem integrates two independent A/D converters: the SDADC24 supports programmable gain, 7.813 kHz sampling, and PLL-synchronized clocking from SOSC, while the ADC12 provides 4-channel conversion with internal reference and temperature sensor input.
Power management includes six low-voltage detectors (LVD0–LVD_VRTC), multiple clock sources (HOCO/MOCO/LOCO/SOSC/MOSC), and Event Link Controller (ELC) for autonomous peripheral triggering without CPU intervention. The 32-bit MACL unit supports 24-channel buffered multiply-accumulate operations with independent address access-critical for real-time sensor fusion in edge-node applications.
