Product details
Overview
R7FA6T2BD3CFP#BA1 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, 24-bit Sigma-Delta ADC (4-channel), 12-bit ADC (2-channel), segment LCD controller (45 seg × 4 com), independent power supply RTC, and AES-128/256 + 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 R7FA6T2BD3CFP#BA1 datasheet, R7FA6T2BD3CFP#BA1 pinout, R7FA6T2BD3CFP#BA1 application, or R7FA6T2BD3CFP#BA1 equivalent, this device delivers verified low-power operation down to 1.6 V, integrated SDADC24 with programmable gain amplifier, hardware-accelerated cryptographic functions, and full support for functional safety diagnostics including CAC, CRC, DOC, and IWDT-critical for IEC 61508-compliant embedded systems.
Technical Context
The R7FA6T2BD3CFP#BA1 implements the Armv8-M architecture with Memory Protection Unit (8 regions) and CoreSight™ MTB-M23 trace, enabling secure, deterministic execution in safety-critical environments. Its clock system integrates HOCO (24/32/48/64 MHz), SOSC (32.768 kHz), MOSC (1–20 MHz), and a dedicated PLL for SDADC24 sampling at 7.813/8.333 kHz.
Analog subsystems include two independent A/D converters: ADC12 supports 2-channel single-ended conversion with internal reference and temperature sensor input, while SDADC24 provides 4 differential/single-ended inputs with PGA, digital filtering, and phase adjustment-both feed into the Data Transfer Controller (DTC) for autonomous data movement without CPU intervention.
