Product details
Overview
R7FA4M3AD2CBQ#BC0 from Renesas is a 100 MHz Arm Cortex-M33 microcontroller with 512 KB code flash, 8 KB data flash, and 128 KB SRAM (with ECC), designed for secure industrial HMI and connected edge nodes requiring USB FS, CAN, SDHI, and capacitive touch. It operates from 2.7–3.6 V across –40°C to +85°C.
For engineers reviewing the R7FA4M3AD2CBQ#BC0 datasheet, R7FA4M3AD2CBQ#BC0 pinout, R7FA4M3AD2CBQ#BC0 application, or R7FA4M3AD2CBQ#BC0 equivalent, key selection considerations include its 64-pin BGA package, TrustZone-enabled security architecture, dual CAN interfaces, integrated CTSU for touch UI, and QSPI support for external memory expansion.
Technical Context
The R7FA4M3AD2CBQ#BC0 implements Armv8-M with TrustZone, enabling hardware-isolated secure/non-secure worlds. Its Secure Crypto Engine 9 accelerates AES, RSA, ECC, SHA256, and GHASH, while tamper detection pins and lifecycle management enforce device integrity.
It integrates dual 12-bit ADCs (5 Msps interleaved), dual 12-bit DACs, temperature sensor, RTC with VBATT backup, six AGT timers, four GPT32 channels, and event-driven peripherals via ELC-enabling deterministic real-time control without CPU overhead.
