Product details
Overview
R7FA6T2AB3CFM#AA1 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 supply RTC, and hardware AES/TRNG security. It targets battery-powered industrial HMI, portable medical sensors, and energy metering systems requiring high-precision analog measurement and secure real-time operation.
For engineers reviewing the R7FA6T2AB3CFM#AA1 datasheet, R7FA6T2AB3CFM#AA1 pinout, R7FA6T2AB3CFM#AA1 application, or R7FA6T2AB3CFM#AA1 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 safety features including ECC-SRAM, CAC, and IWDT.
Technical Context
The R7FA6T2AB3CFM#AA1 implements Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight debug support. Its analog subsystem integrates a 24-bit sigma-delta ADC with programmable gain amplifier, differential input support across 4 channels, and dual-clock sourcing (PLL-multiplied SOSC or MOSC).
System-level timing includes independent power supply RTC with calendar mode (2000–2099), AGT/AGTW timers for low-power event counting, and Event Link Controller (ELC) enabling peripheral-to-peripheral triggering without CPU intervention-critical for deterministic low-power sensor node operation.
