Product details
Overview
R7FA4M3AE2CBQ#BC0 from Renesas Electronics is a 100 MHz Arm Cortex-M33 microcontroller with 768 KB code flash, 8 KB data flash, and 128 KB SRAM (with ECC), designed for secure industrial HMI and connected edge devices requiring USB FS, CAN, SDHI, and capacitive touch. It integrates Secure Crypto Engine 9, Arm TrustZone, and operates from -40°C to +85°C in a 64-pin BGA package.
For engineers reviewing the R7FA4M3AE2CBQ#BC0 datasheet, R7FA4M3AE2CBQ#BC0 pinout, R7FA4M3AE2CBQ#BC0 application, or R7FA4M3AE2CBQ#BC0 equivalent, key selection criteria include its 64-pin FBGA footprint, dual CAN 2.0B support, QSPI interface for external memory, integrated CTSU for touch panels, and hardware-accelerated AES/RSA/SHA256 for firmware integrity and secure boot.
Technical Context
The R7FA4M3AE2CBQ#BC0 implements Armv8-M with TrustZone, enabling secure/non-secure world isolation across flash, SRAM, and peripherals - up to three secure regions in code flash and two in data flash. Its dual CAN modules comply with ISO 11898-1 and support 32 configurable mailboxes with standard/extended addressing.
It features a dual-unit 12-bit ADC (ADC12) with 5 Msps interleaved sampling, two 12-bit DACs (DAC12), and a dedicated Capacitive Touch Sensing Unit (CTSU) supporting up to 20 electrodes. Clock management includes PLL, HOCO/MOCO/LOCO oscillators, and CAC for frequency accuracy verification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
