FAQ

What is the maximum operating frequency of the R7FA6M5AG3CFB#AA0?

The R7FA6M5AG3CFB#AA0 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This clock speed is achieved via the integrated PLL driven by the main oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The device maintains this performance across its full industrial temperature range (-40°C to +105°C) with appropriate voltage regulation and thermal design. R7FA6M5AG3CFB#AA0 supports dynamic clock scaling to balance performance and power consumption in real-time applications.

Does the R7FA6M5AG3CFB#AA0 support Ethernet connectivity?

Yes, the R7FA6M5AG3CFB#AA0 integrates a fully compliant IEEE 802.3 Ethernet MAC controller (ETHERC) with RMII interface support. It connects directly to external PHY devices and works in conjunction with the Ethernet DMA Controller (EDMAC) for zero-copy packet transfers. The R7FA6M5AG3CFB#AA0 does not include a physical layer transceiver, so an external RMII-compliant PHY (e.g., LAN8742A) is required. This implementation meets industrial Ethernet timing requirements and supports IEEE 1588 precision time protocol when configured with timestamping registers.

What security features are implemented in the R7FA6M5AG3CFB#AA0?

The R7FA6M5AG3CFB#AA0 includes Arm TrustZone for hardware-enforced secure/non-secure world separation, Secure Crypto Engine 9 (SCE9) with AES-128/256, RSA-2048/3072, ECC P-256/P-384, and SHA224/SHA256 acceleration, tamper detection pins, and device lifecycle management. These features enable secure boot, encrypted firmware updates, and protected key storage. R7FA6M5AG3CFB#AA0 also supports secure debug authentication and memory protection unit (MPU) regions for both secure and non-secure code execution - fulfilling PSA Certified Level 2 and SESIP certification prerequisites.

How many CAN FD interfaces does the R7FA6M5AG3CFB#AA0 provide?

The R7FA6M5AG3CFB#AA0 integrates two independent CAN FD controllers compliant with ISO 11898-1, each supporting classical CAN and CAN FD frames up to 5 Mbps. Each channel provides 16 transmit and 16 receive message buffers with configurable acceptance filtering. These interfaces operate independently with separate clock domains and interrupt vectors, enabling simultaneous communication with multiple CAN FD networks - such as vehicle subsystems or industrial fieldbus segments. R7FA6M5AG3CFB#AA0's CAN FD modules support bit-rate switching and flexible data-length payloads up to 64 bytes.

What is the flash memory configuration of the R7FA6M5AG3CFB#AA0?

The R7FA6M5AG3CFB#AA0 contains 1.5 MB of on-chip code flash memory organized in dual banks, enabling background programming and SWAP operations for robust firmware updates. It also includes 8 KB of data flash rated for 100,000 program/erase cycles, and 512 KB of SRAM with configurable error detection (448 KB parity + 64 KB ECC). This memory architecture supports fail-safe over-the-air updates, secure key storage in data flash, and fault-tolerant real-time data buffering. R7FA6M5AG3CFB#AA0's flash controller supports read-while-write capability and secure erase functions.
