The R7FA6M4AD3CFB#BA0 integrates Arm TrustZone for hardware-isolated secure/non-secure worlds, Secure Crypto Engine 9 (SCE9) supporting AES-128/256, RSA-2048/4096, ECC, and SHA224/256, plus tamper detection pins, secure pin multiplexing, and device lifecycle management. These features collectively provide root-of-trust capabilities, secure boot, encrypted firmware updates, and runtime protection for sensitive keys and data in the R7FA6M4AD3CFB#BA0.
How many analog-to-digital converter (ADC) channels does the R7FA6M4AD3CFB#BA0 support?
The R7FA6M4AD3CFB#BA0 includes two independent 12-bit successive approximation ADC units (ADC12): Unit 0 supports up to 12 input channels, Unit 1 supports up to 10, with three shared analog input pins (AN000/AN100, AN001/AN101, AN002/AN102), yielding up to 19 total analog input pins. Both units accept internal temperature sensor and reference voltage inputs, enabling precision thermal monitoring and calibration within the R7FA6M4AD3CFB#BA0.
What package type and pin count does the R7FA6M4AD3CFB#BA0 use?
The R7FA6M4AD3CFB#BA0 uses a 144-pin LQFP package (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch, RoHS-compliant and lead-free (Sn only).
