FAQ

What is the maximum operating frequency of the R7FA6M5AG3CFP#BA0?

The R7FA6M5AG3CFP#BA0 features an Arm Cortex-M33 core with a maximum operating frequency of 200 MHz. This speed is achievable under specified conditions: VCC = 2.7–3.6 V and operating temperature range of -40°C to +105°C. The core uses PLL-based clock generation with multiple internal oscillators (HOCO, MOCO, LOCO) and external crystal support (8–24 MHz) to maintain timing accuracy across voltage and temperature variations. The R7FA6M5AG3CFP#BA0 achieves this performance while maintaining low power consumption through dynamic clock gating and multiple low-power modes.

Does the R7FA6M5AG3CFP#BA0 support CAN FD, and how many channels are available?

Yes, the R7FA6M5AG3CFP#BA0 supports CAN with Flexible Data-rate (CAN FD) and includes two independent CAN FD controllers. Each channel supports ISO 11898-1 compliance, classical CAN frames, and CAN FD frames up to 5 Mbps. Each controller provides 16 transmit buffers and 16 receive buffers, enabling high-throughput, deterministic communication in automotive and industrial networks. The R7FA6M5AG3CFP#BA0 implements CAN FD with bit-rate switching, CRC-17 for FD frames, and automatic retransmission - all handled in hardware without CPU intervention.

What security features does the R7FA6M5AG3CFP#BA0 integrate beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5AG3CFP#BA0 integrates the Secure Crypto Engine 9 (SCE9), which provides hardware-accelerated symmetric (AES-128/256), asymmetric (RSA-2048, ECC-P256, DSA), and hash (SHA224/256, GHASH) operations. It includes tamper detection pins, secure key management with protected storage, power analysis resistance, and device lifecycle management. The R7FA6M5AG3CFP#BA0 also supports secure boot with immutable root-of-trust, runtime integrity checking via Cyclic Redundancy Check (CRC) calculator, and secure firmware updates using dual-bank flash SWAP functionality - all enforced by TrustZone-isolated execution environments.

What is the package type and pin count of the R7FA6M5AG3CFP#BA0?

The R7FA6M5AG3CFP#BA0 uses a 100-pin LQFP package (PLQP0100KB-B), measuring 14 mm × 14 mm with 0.5 mm pitch. It provides 75 general-purpose I/O pins, 14 of which are 5-V tolerant, along with dedicated power (VCC/VSS/VBATT), clock (XTAL/EXTAL/XCIN/XCOUT), reset (RES), debug (SWDIO/SWCLK/SWO), and peripheral interface pins. This package is rated for -40°C to +105°C operation and is compatible with standard PCB assembly processes. The R7FA6M5AG3CFP#BA0's pinout is documented in Table 1.15 of the R01DS0366EJ0150 datasheet, with function multiplexing managed via register-controlled pin configuration.

How much SRAM and flash memory does the R7FA6M5AG3CFP#BA0 include?

The R7FA6M5AG3CFP#BA0 includes 512 KB of on-chip SRAM with configurable error detection: 64 KB protected by Error Correction Code (ECC) and 448 KB protected by parity. It also provides 1.5 MB of dual-bank code flash memory supporting background programming, SWAP operations, and read-while-write capability - essential for robust firmware updates. Additionally, it integrates 8 KB of data flash memory rated for 100,000 program/erase cycles, intended for parameter storage and calibration data. These memory resources are accessible across both secure and non-secure worlds under TrustZone control, with MPU enforcement preventing unauthorized access in the R7FA6M5AG3CFP#BA0.
